text: Radio telescopes may need to be extremely large in order to receive signals with high signal-to-noise ratio. Also since angular resolution is a function of the diameter of the "objective" in proportion to the wavelength of the electromagnetic radiation being observed,  radio telescopes have to be much larger in comparison to their optical counterparts. For example, a 1-meter diameter optical telescope is two million times bigger than the wavelength of light observed giving it a resolution of roughly 0.3 arc seconds, whereas a radio telescope "dish" many times that size may, depending on the wavelength observed, only be able to resolve an object the size of the full moon (30 minutes of arc).

text: A high quality image requires a large number of different separations between telescopes. Projected separation between any two telescopes, as seen from the radio source, is called a baseline. For example, the Very Large Array (VLA) near Socorro, New Mexico has 27 telescopes with 351 independent baselines at once, which achieves a resolution of 0.2 arc seconds at 3 cm wavelengths. Martin Ryle's group in Cambridge obtained a Nobel Prize for interferometry and aperture synthesis. The Lloyd's mirror interferometer was also developed independently in 1946 by Joseph Pawsey's group at the University of Sydney. In the early 1950s, the Cambridge Interferometer mapped the radio sky to produce the famous 2C and 3C surveys of radio sources. An example of a large physically connected radio telescope array is the Giant Metrewave Radio Telescope, located in Pune, India. The largest array, the Low-Frequency Array (LOFAR), is currently being constructed in western Europe, consisting of about 20,000 small antennas in 48 stations distributed over an area several hundreds of kilometers in diameter, and operates between 1.25 and 30 m wavelengths. VLBI systems using post-observation processing have been constructed with antennas thousands of miles apart.  Radio interferometers have also been used to obtain detailed images of the anisotropies and the polarization of the Cosmic Microwave Background, like the CBI interferometer in 2004.

text: During the next three years the telescope room was closed to the public while the work proceeded. Only the balcony was available and observations were carried out with small instruments. The telescope was completed in 1950 and described as "the first of its kind in the world." Unfortunately, it was purely for photographic work, which rather contradicted the above assurance.However, matters took a different course. The expansion of the city north and west and the development of sodium and mercury street-lighting hampered the work of stellar photography, so in February, 1951  Bruce and Professor Freundlich suggested that the pilot telescope be transferred to St. Andrews University Observatory, eleven miles (18 km) to the south, for better conditions and proximity to the workshops. The Mills would then receive in exchange the 10-inch (25 cm.) Cooke refracting telescope formerly used as a student training instrument and now surplus to requirements. At first the Town Council refused, and there was much correspondence in the local press, and indignation among local amateurs, that the University should interfere with the affairs of a public institution.  Professor W.H.M. Greaves, had succeeded Professor Sampson as Astronomer Royal for Scotland, was called upon to advise on the matter.  In view of the scientific benefits of the move, and lack of interest shown by University College, Dundee, he recommended that the transfer take place. This was done at the University's expense, and on the understanding that the two telescopes were on mutual loan.The  refractor had to be modified slightly to fit the Mills dome, and the dew-cap cannot safely be used.  However, it proved to be a much superior instrument for public viewing to the old Newtonian reflector. Originally built in 1871 it was, at one time, privately owned by Walter Goodacre, president of the British Astronomical Association (B. A. A. ), who lived in the village of Four Marks, near Winchester. The telescope was used there by many famous amateurs involved in the work of the B. A. A. and was always described by them as "the excellent 10-inch Cooke refractor".  It is particularly good for observing fine lunar and planetary detail and although not basically designed for photographic work, the lens is so good that, with modern cameras, good photographs can be taken. The Observatory has also acquired a number of smaller telescopes over the years.

text: Isaac Newton built his reflecting telescope as a proof for his theory that white light is composed of a spectrum of colours. He had concluded that the lens of any refracting telescope would suffer from the dispersion of light into colours (chromatic aberration). The telescope he constructed used mirrors as the objective which bypass that problem. To create the primary mirror Newton used a custom composition of metal consisting of six parts copper to two parts tin, an early composition of speculum metal. He devised means for shaping and grinding the mirror and may have been the first to use a pitch lap to polish the optical surface. He chose a spherical shape for his mirror instead of a parabola to simplify construction: he had satisfied himself that the chromatic, and not the spherical aberration, formed the chief faults of refracting telescopes. He added to his reflector what is the hallmark of the design of a "Newtonian telescope", a secondary "diagonal" mirror near the primary mirror's focus to reflect the image at 90° angle to an eyepiece mounted on the side of the telescope. This unique addition allowed the image to be viewed with minimal obstruction of the objective mirror. He also made all the tube, mount, and fittings.

text: In 1980, it was used as part of the new MERLIN array with a series of smaller radio telescopes controlled from Jodrell Bank. With baselines of up to 217 km (135 mi), this gave a resolution around 0.05 arcminutes. An upgraded version of this became a national facility in 1992. It has also been used in Very Long Baseline Interferometry, with telescopes across Europe (the European VLBI Network), giving a resolution of around 0.001 arcseconds. Around half of the telescope's observing time is now spent doing interferometry with other telescopes. It is planned that the telescope will work as part of an interferometer with the Radioastron (Russian) and VLBI Space Observatory Programme (Japanese) orbital radio satellites, providing yet larger baselines and higher resolutions.

text: A space observatory is any instrument, such as a telescope, in outer space which is used for observation of distant planets, galaxies, and other outer space objects. In 1946, American theoretical astrophysicist Lyman Spitzer was the first to conceive the idea of a telescope in outer space, a decade before the Soviet Union launched the first artificial satellite, Sputnik into orbit. Spitzer's proposal called for a large telescope that would not be hindered by Earth's atmosphere. After lobbying in the 1960s and 1970s for such a system to be built, Spitzer's vision ultimately materialized into the world's first space-based optical telescope, Hubble Space Telescope, which was launched on April 20, 1990 by the Space Shuttle Discovery (STS-31).

text: The telescope was located on the grounds of Observatory House, Herschel's house in Slough, between 1789 and 1840. The first observation with the telescope was on 19 February 1787, when Herschel pointed the then-incomplete telescope towards the Orion nebula, which he observed by crawling into the telescope and using a hand-held eyepiece: "The apparatus for the 40-foot telescope was by this time so far completed that I could put the mirror into the tube and direct it to a celestial object; but having no eye-glass fixed, not being acquainted with the focal length which was to be tried, I went into the tube, and laying down near the mouth of it I held the eye-glass in my hand, and soon found the place of the focus. The object I viewed was the nebula in the belt of Orion, and I found the figure of the mirror, though far from perfect, better than I had expected. It showed four small stars in the nebula and many more. The nebula was extremely bright."

text: Following Heinrich Hertz's establishment of the existence of electromagnetic radiation in the late 1880s, a variety of terms were initially used for the phenomenon, with early descriptions of the radiation itself including "Hertzian waves", "electric waves", and "ether waves", while phrases describing its use in communications included "spark telegraphy", "space telegraphy", "aerography" and, eventually and most commonly, "wireless telegraphy". However, "wireless" included a broad variety of related electronic technologies, including electrostatic induction, electromagnetic induction and aquatic and earth conduction, so there was a need for a more precise term referring exclusively to electromagnetic radiation.

The telescoping cylinder incorporates a piston rod nested within a series of hollow stages of increasing diameter.  Upon actuation, the piston rod and each succeeding stage "telescopes" out as a segmented piston.  The main benefit of this design is the allowance for a notably longer stroke than would be achieved with a single-stage cylinder of the same collapsed (retracted) length.  One cited drawback to telescoping cylinders is the increased potential for piston flexion due to the segmented piston design.  Consequently, telescoping cylinders are primarily utilized in applications where the piston bears minimal side loading.

text: The first person to use a telescope to observe the night sky and record his observations was the Italian scientist Galileo Galilei in 1609. When he turned the telescope toward some of the nebulous patches recorded by Ptolemy, he found they were not a single star, but groupings of many stars. For Praesepe, he found more than 40 stars. Where previously observers had noted only 6-7 stars in the Pleiades, he found almost 50. In his 1610 treatise Sidereus Nuncius, Galileo Galilei wrote, "the galaxy is nothing else but a mass of innumerable stars planted together in clusters." Influenced by Galileo's work, the Sicilian astronomer Giovanni Hodierna became possibly the first astronomer to use a telescope to find previously undiscovered open clusters. In 1654, he identified the objects now designated Messier 41, Messier 47, NGC 2362 and NGC 2451.

text: His importance in the context of Indian art scene is much beyond a simplistic cultural exchange. On the international art scene, he represents the region as a whole, and he shares a deep connection with the country. The artist had his very first international solo in New Delhi with Nature Morte in 2004. Looking back at those times, he had once stated: “India was my launch pad. I didn’t consider myself a professional artist till that show in 2004. It changed my approach.” He has not looked back since then, and has now become a poster boy for the Indian art gallery circuit. One edition of his work "Red Carpet-1" was auctioned at Sotheby’s New York on 16 May 2008, for a record price of 623,000 USD, highest price ever paid for a work of art produced by a Pakistani.

text: The proposal for a larger aircraft-mounted telescope was officially presented in 1984 and called for a Boeing 747 to carry a three-meter telescope. The preliminary system concept was published in 1987 in a Red Book. It was agreed that Germany would contribute 20% of the total cost and provide the telescope. However, the reunification of Germany and budget cuts at NASA led to a five-year slide in the project. NASA then contracted the work out to the Universities Space Research Association (USRA), and in 1996, NASA and DLR (the German Space Agency or Deutsches Zentrum fur Luft- und Raumfahrt) signed a memorandum of understanding to build and operate SOFIA.

text: A refracting telescope (also called a refractor) is a type of optical telescope that uses a lens as its objective to form an image (also referred to a dioptric telescope). The refracting telescope design was originally used in spy glasses and astronomical telescopes but is also used for long focus camera lenses. Although large refracting telescopes were very popular in the second half of the 19th century, for most research purposes the refracting telescope has been superseded by the reflecting telescope which allows larger apertures. A refractor's magnification is calculated by dividing the focal length of the objective lens by that of the eyepiece.

text: Performing astronomy from ground-based observatories on Earth is limited by the filtering and distortion of electromagnetic radiation (scintillation or twinkling) due to the atmosphere. Some terrestrial telescopes can reduce atmospheric effects with adaptive optics. A telescope orbiting Earth outside the atmosphere is subject neither to twinkling nor to light pollution from artificial light sources on Earth. As a result, the angular resolution of space telescopes is often much smaller than a ground-based telescope with a similar aperture.

text: Atmosphere and Telescope Simulators are used because time in science-worthy class telescopes are generally expensive and difficult to obtain. Telescope facilities are often uncomfortable for operators working on site long periods of time. Researchers have expressed the need for a laboratory tool which could provide better and cheaper accessibility than a real telescope, and better characterization than computer simulations. A LED based illumination system in which five Galilean collimation systems have been used is reported on. It is part of a turbulence simulator for the evaluation of on ground telescopes instrumentation developed by INTA (optics) and LIDAX (opto-mechanics)  for the IAC called IACATS.

text: Ethanimine is an organonitrogen compound classified as an imine.  It is not well known terrestrially, but has been detected in abundance towards Sagittarius B2 (Sgr B2), a dense interstellar cloud in between stars towards the galactic center of the Milky Way. The distance between the Sgr B2 cloud and center of galaxy is 100 pc (1 pc=3.26l y). Ethanimine is mainly found in hot cores of ISM clouds; in case of Sgr B2, the region would be the Sgr B2 N and Sgr B2 M. The radio telescopes such as the Green Bank Telescope and NRAO (measures radio frequency light lambda ranging from 1–300 GHz) are able to detect organic molecules such as ethanimines because its internal energy transition, more specifically the rotational transition is within the radio frequency of 14085 MHz=140.8 GHz.

text: A possible supernova was first noticed during an observation in June 2015 by ASAS-SN’s twin 14-cm telescopes in Chile; the team gave it the designation ASASSN-15lh. The supernova appeared as a transient dot of light on an image and was confirmed with additional observations from other telescopes. The spectrum of ASASSN-15lh was provided by the 2.5-meter du Pont Telescope in Chile. The Southern African Large Telescope was used to determine the redshift, and hence the distance and luminosity. The Swift space telescope also contributed observations. On 24 July, the event formally received the supernova designation SN 2015L from the Central Bureau of Astronomical Telegrams.

text: During his early years, Marconi had an interest in science and electricity and in the early 1890s he began working on the idea of "wireless telegraphy"—i.e., the transmission of telegraph messages without connecting wires as used by the electric telegraph. This was not a new idea; numerous investigators and inventors had been exploring wireless telegraph technologies and even building systems using electric conduction, electromagnetic induction and optical (light) signalling for over 50 years, but none had proven technically and commercially successful. A relatively new development came from Heinrich Hertz, who demonstrated beginning in 1888 that one could produce and detect electromagnetic radiation—now generally known as radio waves, at the time more commonly called "Hertzian waves" or "aetheric waves".

text: Animals have been known to perceive the infrasonic waves going through the earth by natural disasters and can use these as an early warning. A recent example of this is the 2004 Indian Ocean earthquake and tsunami. Animals were reported to flee the area hours before the actual tsunami hit the shores of Asia. It is not known for sure that this is the cause; some have suggested that it may have been the influence of electromagnetic waves, and not of infrasonic waves, that prompted these animals to flee.

text: With the development of fast Internet in the last part of the 20th century along with advances in computer-controlled telescope mounts and CCD cameras 'Remote Telescope' astronomy is now a viable means for amateur astronomers not aligned with major telescope facilities to partake in research and deep sky imaging. This enables the imager to control a telescope a large distance away in a dark location. The observers can image through the telescopes using CCD cameras. Imaging can be done regardless of the location of the user or the telescopes they wish to use. The digital data collected by the telescope is then transmitted and displayed to the user by means of the Internet. An example of a digital remote telescope operation for public use via the Internet is The Bareket Observatory.

text: As the interest in transients has intensified because study of them helps astrophysicists to understand the mechanisms which produced our universe, telescopes with larger fields of view are coming into use. These, such as the Palomar Transient Factory, the Gaia (spacecraft) and the LSST, are able to spot many more such occurrences. The ability of modern instruments to observe in wavelengths invisible to the human eye (radio waves, infrared, ultraviolet, x-ray) increases the amount of information that may be obtained when a transient is studied. The proposed ULTRASAT satellite will observe a field of more than 200 square degrees continuously in the ultraviolet range. This wavelength is particularly important for detecting supernovae within minutes of their occurrence.

text: The final was contested by England and Australia. Just before half time, England led 21-0 through tries from Andrew Harriman, Lawrence Dallaglio and Tim Rodber, all converted by Nick Beal. Michael Lynagh scored a try before haf time, but failed to convert his own try. In the second half Australia hit back strongly and first David Campese and then Semi Taupeaafe scored further tries, the latter also converted by Michael Lynagh. However, time ran out on the Australians and it was England captain "Prince" Andrew Harriman who was presented with the Melrose Cup by the Princess Royal.  Adedayo Adebayo, a member of that victorious side later recalled how surprising the victory had been to the players involved in it. He said "We were basically a scratch side. We got together for the first time as a team the week before, played one practice match and went on to win! But there were a lot of quality players in that side and looking back that's why we were able to wing it slightly - the talent came through. Looking back though we had no expectations of winning at the start. We didn't know how far we would go. It just happened."

text: Bob Nave, keyboardist for the Lemon Pipers in the late 1960s (whose big hit was the song "Green Tambourine"), was a late-night DJ for WOXR in the early 1970s. Other early to mid-1970s on-air personalities for the station included Rick Sellers, Ray Smith and Ed Pharr. Nave's program featured a brief comedy program known as "The Purple Nurd," produced by four high school students from Fairfield, Ohio who billed themselves as HPW Squared Productions.

text: By the early 1960s, Mount Stromlo had developed into one of the leading facilities for observational astronomy in the southern hemisphere. However, Bok appreciated the limitations of the site of Mount Stromlo due to weather and increasing light pollution, and he initiated a site-testing program which stretched across the country. In 1962, Siding Spring Mountain was chosen for the creation of a world-class telescope facility. As Siding Spring grew, Bok threw his support behind a new project: what would become Australia's largest optical telescope, the  Anglo-Australian Telescope.

text: Leuschner Observatory is home to a single  radio telescope. The telescope was one of the prototypes for the Allen Telescope Array that were tested at Leuschner, and has since been used in the undergraduate radio astronomy lab. The telescope operates between 1320–1740 MHz and uses an 8192 element spectrometer with spectral resolution of about 1.5 kHz and a 12 MHz bandwidth. The operating range allows for it to be used to observe the 21-cm hydrogen line as well as hydroxyl lines from astrophysical masers.

text: The design is named after Dobson because he is credited for being the first person to have combined all these construction techniques in a single telescope design. He was reluctant to take credit, however, pointing out that he built it that way because it was all he needed. In his own words, he jokes that he was "too retarded" to build a more sophisticated telescope with an equatorial telescope mount. With its simplicity of construction and use, the Dobsonian has become a very popular design today, particularly for large amateur telescopes.

text: The transit method also makes it possible to study the atmosphere of the transiting planet. When the planet transits the star, light from the star passes through the upper atmosphere of the planet. By studying the high-resolution stellar spectrum carefully, one can detect elements present in the planet's atmosphere.  A planetary atmosphere (and planet for that matter) could also be detected by measuring the polarisation of the starlight as it passed through or is reflected off the planet's atmosphere.

text: The beginning of the 20th century saw construction of the first of the "modern" large research reflectors, designed for precision photographic imaging and located at remote high altitude clear sky locations such as the 60-inch Hale telescope of 1908, and the  Hooker telescope in 1917, both located at Mount Wilson Observatory. These and other telescopes of this size had to have provisions to allow for the removal of their main mirrors for re-silvering every few months. John Donavan Strong, a young physicist at the California Institute of Technology, developed a technique for coating a mirror with a much longer lasting aluminum coating using thermal vacuum evaporation. In 1932, he became the first person to "aluminize" a mirror; three years later the  and  telescopes became the first large astronomical telescopes to have their mirrors aluminized. 1948 saw the completion of the  Hale reflector at Mount Palomar which was the largest telescope in the world up until the completion of the massive  BTA-6 in Russia twenty-seven years later. The Hale reflector introduced several technical innovations used in future telescopes, including hydrostatic bearings for very low friction, the Serrurier truss for equal deflections of the two mirrors as the tube sags under gravity, and the use of Pyrex low-expansion glass for the mirrors. The arrival of substantially larger telescopes had to await the introduction of methods other than the rigidity of glass to maintain the proper shape of the mirror.

text: Between 1972 and 1973, the telescope was used for "a detailed survey of the radio sources in a limited area of the sky … up to the sensitivity limit of the instrument". Among the objects catalogued was the first gravitational lens, which was confirmed optically in 1979 after its position was found to coincide with a pair of faint blue stars by using the Mark I as an interferometer with the Mark II. The telescope was also involved in the detection of the first Einstein ring in 1998, in conjunction with observations made with the Hubble Space Telescope.

text: The Newtonian telescope is a type of reflecting telescope invented by the British scientist Sir Isaac Newton (1642–1727), using a concave primary mirror and a flat diagonal secondary mirror. Newton’s first reflecting telescope was completed in 1668 and is the earliest known functional reflecting telescope. The Newtonian telescope's simple design makes it very popular with amateur telescope makers.

text: The California Extremely Large Telescope (CELT) was a proposal for an extremely large telescope design first proposed in the 1990s by a consortium of Californian Universities. The design was for a segmented 30 m diameter astronomical telescope. The CELT had a positive reception and continued to be developed, and was renamed The Thirty Meter Telescope around 2003-4. The CELT was one of the earlier and more successful proposals for extremely large telescopes.

text: Largest does not always equate to being the best telescopes, and overall light gathering power of the optical system can be a poor measure of a telescope's performance. Space-based telescopes, such as the Hubble Space Telescope, take advantage of being above the Earth's atmosphere to reach higher resolution and greater light gathering through longer exposure time. Location in the northern or southern hemisphere of the Earth can also limit what part of the sky can be observed.

text: The telescope is more a discovery of optical craftsmen than an invention of a scientist. The lens and the properties of refracting and reflecting light had been known since antiquity and theory on how they worked were developed by ancient Greek philosophers, preserved and expanded on in the medieval Islamic world, and had reached a significantly advanced state by the time of the telescope's invention in early modern Europe. But the most significant step cited in the invention of the telescope was the development of lens manufacture for spectacles, first in Venice and Florence in the thirteenth century, and later in the spectacle making centers in both the Netherlands and Germany. It is in the Netherlands in 1608 where the first recorded optical telescopes (refracting telescopes) appeared. The invention is credited to the spectacle makers Hans Lippershey and Zacharias Janssen in Middelburg, and the instrument-maker and optician Jacob Metius of Alkmaar.

text: The album cover of Motivation Radio features Hillage standing on a shoreline holding a Statocaster guitar, with a large radio telescope in the background further along the bay. The radio telescope in question is the radio telescope at Parkes Observatory in New South Wales, Australia, superimposed on top of a shoreline picture. Hillage's father bought him the Stratocaster on the cover because Steve went to a public school - the City of London School - and "did quite well" on his O levels and won a scholarship, meaning that his father did not have to pay fees any more and bought him the guitar. Hillage recalled that "We found it through Exchange & Mart or Melody Maker - one or the other, I don't know." American art director Bob Cato is credited on the album sleeve for "design and photography."

text: Since the Earth is constantly rotating, telescopes and equipment are rotated in the opposite direction to follow the apparent motion of the stars overhead (called diurnal motion).  This is accomplished by using either equatorial or computer-controlled altazimuth telescope mounts to keep celestial objects centered while the earth rotates. All telescope mount systems suffer from induced tracking error due to imperfect motor drives and mechanical sag of the telescope. Tracking errors are corrected by keeping a selected aiming point, usually a bright guide star, centered during the entire exposure. Sometimes (as in the case of comets) the object to be imaged is moving, so the telescope has to be kept constantly centered on that object. This guiding is done through a second co-mounted telescope called a "guide scope" or via some type of "off-axis guider", a device with a prism or optical beam splitter that allows the observer to view the same image in the telescope that is taking the picture. Guiding was formerly done manually throughout the exposure with an observer standing at (or riding inside) the telescope making corrections to keep a cross hair on the guide star. Since the advent of computer-controlled systems this is accomplished by an automated systems in professional and even amateur equipment.

text: The main aim for the telescope when constructed was to use it in conjunction with the Lovell Telescope as a fully steerable interferometer to determine the sizes of radio sources. It was not known what size the radio sources would be, and so the optimal telescope separation was not known (the separation is inversely proportional to the resolution of the interferometer). As a result, the telescope was built such that it could be completely disassembled and reassembled on a new site within 6 months.

text: Once the Space Telescope project had been given the go-ahead, work on the program was divided among many institutions. Marshall Space Flight Center (MSFC) was given responsibility for the design, development, and construction of the telescope, while Goddard Space Flight Center was given overall control of the scientific instruments and ground-control center for the mission. MSFC commissioned the optics company Perkin-Elmer to design and build the Optical Telescope Assembly (OTA) and Fine Guidance Sensors for the space telescope. Lockheed was commissioned to construct and integrate the spacecraft in which the telescope would be housed.

text: Team scientists used 137 different microorganism species, including extremophiles that were isolated from Earth's most extreme environments, and cataloged how each life form uniquely reflects sunlight in the visible and near-infrared to the short-wavelength infrared (0.35–2.5 µm) portions of the electromagnetic spectrum. This database of individual reflection 'fingerprints' (spectrum) might be used by astronomers as biosignatures to find large colonies of microscopic life on distant exoplanets. A combination of organisms would produce a mixed spectrum, also cataloged,  of light bouncing off the planet. The goal of the catalog is to provide astronomers with a baseline comparison to help scientists interpret the data that will come back from telescopes like WFIRST and E-ELT.

text: In 2008, the TMT corporation selected two semi-finalists for further study, Mauna Kea and Cerro Amazones. In July 2009, Mauna Kea was selected. Once TMT selected Mauna Kea, the project began a regulatory and community process for approval. Mauna Kea is ranked as one of the best sites on Earth for telescope viewing and is home to 13 other telescopes built at the summit of the mountain, within the Mauna Kea Observatories grounds. Telescopes generate money for the big island, with millions of dollars in jobs and subsidies gained by the state. The TMT would be one of the most expensive telescopes ever created.

text: The SAFARI imaging spectrometer is the European ‘nerve center’ of Japanese infrared telescope SPICA (Space Infra-Red Telescope for Cosmology and Astrophysics telescope) and is being developed under the leadership of SRON Netherlands Institute for Space Research. SAFARI is an infrared camera with about 6,000 pixels that can make real ‘photos’ of the sky in three adjacent wavelength areas. Using a Fourier transform spectroscopy (FTS) detailed spectral information is obtained, allowing astronomers to determine the chemical composition of the observed celestial sources. TNO is developing the mechanism of this FTS.

text: The Balmer series is characterized by the electron transitioning from n ≥ 3 to n = 2, where n refers to the radial quantum number or principal quantum number of the electron. The transitions are named sequentially by Greek letter: n = 3 to n = 2 is called H-α, 4 to 2 is H-β, 5 to 2 is H-γ, and 6 to 2 is H-δ. As the first spectral lines associated with this series are located in the visible part of the electromagnetic spectrum, these lines are historically referred to as "H-alpha", "H-beta", "H-gamma" and so on, where H is the element hydrogen.

text: With its 70-meter antenna diameter, it is among the largest single dish radio telescopes in the world. It has an advantage in comparison with other large radio telescopes in the fact that the complex includes powerful transmitters that allow active space experiments. Powerful electromagnetic beams can be accurately targeted and the signals received can be analyzed. For this reason, the Yevpatoria RT-70 radio telescope is one of only two in the world that are able to transmit messages to extraterrestrial civilizations. Radio telescopes are highly sensitive detectors of signals from outer space.

text: Each of the three spectrometers was tuned to measure the absorption in a specific range of colors. Each of these ranges includes dozens of dark absorption lines produced by either carbon dioxide or molecular oxygen. The amount of light absorbed in each spectral line increases with the number of molecules along the optical path. OCO's spectrometers measure the fraction of the light absorbed in each of these lines with very high precision. This information was then to be analyzed to determine the number of molecules along the path between the top of the atmosphere and the surface.

text: Again there are technical issues relating to spin, but in several important cases, including electrically charged particles and particles interacting via nuclear forces, the solution to the problem is to impute physical reality to the gauge function θ(x). We say that if the function θ oscillates, it represents a new type of quantum-mechanical wave, and this new wave has its own momentum p = h/λ, which turns out to patch up the discrepancies that otherwise would have broken conservation of momentum. In the context of electromagnetism, the particles A and B would be charged particles such as electrons, and the quantum mechanical wave represented by θ would be the electromagnetic field. (Here we ignore the technical issues raised by the fact that electrons actually have spin 1/2, not spin zero. This oversimplification is the reason that the gauge field θ comes out to be a scalar, whereas the electromagnetic field is actually represented by a vector consisting of V and A.) The result is that we have an explanation for the presence of electromagnetic interactions: if we try to construct a gauge-symmetric theory of identical, non-interacting particles, the result is not self-consistent, and can only be repaired by adding electric and magnetic fields that cause the particles to interact.

text: In "out of bounds" areas, many maps have hollow objects that the player can move through freely. These objects usually are in the distance and are for decoration. The floor or terrain can also be hollow. The floor can appear the same as a normal floor, but moving over it will cause the player to fall as if it does not exist. Depending on the game, after falling a certain distance the player will freeze, die, respawn on the map again or just keep falling. Two good examples are the Nintendo 64 games The Legend of Zelda: Ocarina of Time and The Legend of Zelda: Majora's Mask. In the former, there is a section of "wall" at the entrance to the water temple that will allow players to fall through the ground. Eventually players respawn rather than the game crashing. In the latter, there is a 3-day cycle (after which the moon will fall) that can be surpassed by going to the observatory and looking out the telescope on the last minutes of the final day. If you look out the telescope while the timer is counting down and exit the telescope when the timer hits 0, (if you're lucky) the timer will be gone and you can continue the game without it. The glitch is removed when you play the Song of Time.

text: The Fibre-fed Échelle Spectrograph (FIES) on the Canary Islands' Nordic Optical Telescope was operated in October 2009, using Doppler spectroscopy to gather information that would accompany the gathered photometric observations. The High Resolution Échelle Spectrometer (HIRES) at the W.M. Keck Observatory was also utilized. Use of the WIYN Observatory for speckle imaging found that the host star of KOI-98 was actually a close-knit binary star, which complicated the analysis. A November 2009 operation of the ARIES instrument on the MMT Observatory and the July 2010 use of the PHARO near-infrared camera on the Palomar Observatory's  200 inch Hale telescope used adaptive optics to confirm WIYN's findings. Although suspected as a planet early on, KOI-98 was not included when Kepler-4b, Kepler-5b, Kepler-6b, Kepler-7b, and Kepler-8b were published, as further investigation was still required.

text: The problems with seating the second RSU set the spacewalkers back in the timeline by approximately two hours, but after Altman asked Massimino and Good how they felt, they replied they were doing well and felt fine to continue. Flight controllers on the ground evaluated the consumables for the two spacesuits, and decided that if Massimino recharged his suit's oxygen in the airlock, the pair could safely continue with the battery installation. After moving to the battery unit site, Good and Massimino removed one of the original battery modules from Bay 2 of the telescope, and replaced it with a new unit. The batteries provide power to the telescope when it passes into the Earth's shadow and its solar arrays are not exposed to the sun. The spacewalk officially ended at 20:45 UTC, for a time of seven hours, fifty-six minutes. It was the twentieth spacewalk to service Hubble, bringing the total time in EVA servicing the telescope to one hundred forty-four hours and twenty-six minutes.

text: The native resolution of an interferometer depends not on the size of the individual telescopes (as with a traditional single telescope), but on their separation. Pairs of telescopes with large separations provide sensitivity to small-scale structure, while short spacings are sensitive to large-scale structure on the sky. The 8 SZA telescopes are small enough to be placed very close together, which provides maximum sensitivity to the (large-scale) SZ signal from clusters.  When the SZA is combined with the other telescopes in the CARMA array, which have longer separations and are sensitive to finer angular scales, it can form a complete picture of galaxy clusters at very high resolution.

text: The BTA-6 (Большой Телескоп Альтазимутальный, or Large Altazimuth Telescope), with first light in 1975, was for several years the world's largest single primary mirror optical reflecting telescope. The BTA-6's primary mirror has a diameter of 6 metres (236 inches) and is housed in a 48 m (157.5 ft) diameter dome at an altitude of 2,070 m (6,791 ft).  It held the record from its completion until 1993, when it was surpassed by the Keck 1 telescope, Hawaii. Telescopes of comparable or larger size have subsequently employed flexible or segmented mirrors, and the BTA-6 remained the world's largest rigid-mirror telescope until the advent of spin-casting technology (which produced, for example, the single 8.4-meter primary mirror of the Large Binocular Telescope in the late 1990s). Its altazimuth mounting dictates the need for a field derotation mechanism to maintain the orientation of the field of view.

text: In 2014, Sullivan was honored in the Time 100 list. According to John Glenn, "Kathy is not just an ivory-tower scientist. She was part of NASA's first class of female astronauts, selected in 1978, and went on to fly three shuttle missions. She is the first American woman to walk in space and served aboard the mission that deployed the Hubble Space Telescope. That role in helping humanity look outward has not prevented her from looking homeward. The planet is suffering increasingly severe upheavals, at least partly a result of climate change — droughts, floods, typhoons, tornadoes. I believe my good friend Kathy is the right person for the right job at the right time."

text: Observatory's first radio telescope was a parabolic antenna of  diameter, which was donated by the Marmara Research Center (MAM) of Scientific and Technological Research Council of Turkey (TÜBİTAK). The radio telescope, then called MRT-2, was initially purchased from the Institute of Radio Astronomy in Kharkiv, Ukraine with the financial help of UNIDO in 1996. Built to operate in the radio frequency range of 85-115 GHz, it was intended for the acquisition of carbon monoxide data in the Milky Way. In 1997, the telescope became inoperable, and the Ukrainian technicians were unavailable for its reparature. After some unsuccessful attempts to fix the radio telescope at site, it was handed over in 2000 to Erciyes University, where its rehabilation was carried out between 2001-2002.

text: Ingalls's primary interests were in the areas of astronomy and telescope construction. After reading an article by Russell W. Porter on telescope making, he arranged a visit by Porter to New York in June 1925, out of which came an article later that year in Scientific American. The article was so well received that Ingalls began a series of columns on amateur telescope making, some written in collaboration with Porter. Ingalls and Porter became close friends and the two men remained at the center of the American amateur telescope making community for the next thirty years. A number of articles from the columns, together with illustrations by Porter, were published in book form as Amateur Telescope Making, the first volume of which appeared in 1926, followed by volumes 2 and 3 in 1937 and 1953.  These books helped to create lasting public interest in observational astronomy. The books have come to be called "the bible of telescope making".

text: However, if someone decides to look at the same situation outside of the frame— which rarely happens because people are always convinced that common sense does not require justification— that person will have a completely different understanding of what is in the frame, and feel that common sense no longer makes sense. Continuing the corset example, in our present time it is common sense that corsets are unhealthy and will do more harm than good to a female body. This is why the majority of people these days don’t wear corsets. And when we look back to the old frame from the 19th century, we think that fashion sense of that time is strange. This is the outcome of shifted frames.

text: In 1963 Gascoigne published an article in the journal Nature titled "Towards a Southern Commonwealth Observatory".Gascoigne was then given a significant opportunity that became the focus of the remainder of his paid academic career: to help establish one of the world's largest optical telescopes, at Siding Spring. In the early 1960s, the Australian and British governments proposed a partnership to build a joint optical telescope facility, and Gascoigne was among the experts involved. Former Mount Stromlo director and now head of the Greenwich observatory, Richard Woolley, was prominent in supporting the project from the British end. In 1967, the two governments formally agreed to collaborate on the construction of a large telescope, to be known as the Anglo-Australian Telescope (AAT). Given the existing infrastructure of the ANU's Siding Spring Observatory, the site was readily agreed as the location for the AAT. Gascoigne was one of the four members of the Technical Committee established to guide the telescope's development. He provided leadership on the design and optics of the new telescope, and was made the chief commissioning astronomer in 1974.

text: The RAPTOR system (Rapid Telescopes for Optical Response) is a specialized suite of telescopes designed to detect and track transient objects, including gamma-ray bursts and near-earth objects. RAPTOR was built by a Los Alamos team headed by astrophysicist Tom Vestrand. The system consists of six robotic observatories—RAPTOR-A, -S, -P, -K, and -T are located at Fenton Hill and RAPTOR-B is located at the Los Alamos Neutron Science Center,  away. The telescopes are all networked and controlled by a centralized computer system. The older RAPTOR telescopes, RAPTORs A,B,S and P each consist of a wide-field telescope and a narrow-field telescope. They are mounted on platforms that can swivel to any point in the sky in less than 3 seconds, making them the fastest moving telescopes ever built. Each wide-field telescope has a nominal field of view of 38 by 38 degrees, which equates to being able to cover the sky in eleven patches. Each telescope is actually two telescopes giving stereoscopic vision. There is a zoom mechanism built into each telescope as well. While in monitoring mode, RAPTOR takes two consecutive 30-second exposures through its two wide-field telescopes and analyzes the resulting digital images. If it sees an interesting event, RAPTOR zooms in for a closer look with the two narrow-field telescopes.

text: Radio and submillimeter telescopes use much larger dishes or antennae, which do not have to be made as precisely as the mirrors used in optical telescopes. The Arecibo Observatory uses a 305 m dish, which is the world largest single-dish radio telescope fixed to the ground. The Green Bank Telescope has the world's largest steerable single radio dish with 100 m in diameter. There are largest radio arrays, composed of multiple dishes which have better image resolution but less sensitivity.

text: The main instrument at each TCCON site is a Bruker IFS 125HR (HR for high resolution, ~0.02 cm) or occasionally 120HR Fourier transform spectrometer. Sunlight is directed into the spectrometer by solar tracking mirrors and other optics. The spectrometers measure the absorption of direct sunlight by atmospheric trace gases primarily in the near infrared region. This remote sensing technique produces a precise and accurate measurement of the total column abundance of the trace gas. The main limitation to this technique is that measurements can not be recorded when it is not sunny (i.e. there are no measurements available at nighttime or when there is heavy cloud cover).

text: In electromagnetics, an evanescent field, or  evanescent wave, is an oscillating electric and/or magnetic field which does not propagate as an electromagnetic wave but whose energy is spatially concentrated in the vicinity of the source (oscillating charges and currents). Even when there in fact is an electromagnetic wave produced (e.g., by a transmitting antenna) one can still identify as an evanescent field the component of the electric or magnetic field that cannot be attributed to the propagating wave observed at a distance of many wavelengths (such as the far field of a transmitting antenna).

text: A 14/60 4-door 4-light saloon was road tested by The Times. Head clearance was described as moderate but it was felt there was good width and leg room for two persons in the back seat and the doorways gave "reasonable entrance". Interior fittings included three electric lights, 2-way visors, a sliding roof, three handy ashtrays, an instrument board with large dial clock and speedometer, a telescopic spring steering wheel, wholly automatic chassis lubrication, a jacking system and a windscreen which could be wound out to give a direct view.

Interior fittings included three electric lights, 2-way visors, a sliding roof, three handy ashtrays, an instrument board with large dial clock and speedometer, a telescopic spring steering wheel, wholly automatic chassis lubrication, a jacking system and a windscreen which could be wound out to give a direct view.

text: Even though the nebula has a relatively bright integrated magnitude of 7, it is spread over so large an area that the surface brightness is quite low, so the nebula is notorious among astronomers as being difficult to see. However, an observer can see the nebula clearly in a telescope using an OIII filter (a filter isolating the wavelength of light from doubly ionized oxygen), as almost all light from this nebula is emitted at this wavelength. An  telescope equipped with an OIII filter shows the delicate lacework apparent in photographs, and with an OIII filter almost any telescope could conceivably see this nebula.  Some argue that it can be seen without any optical aid except an OIII filter held up to the eye.

text: The 2.2-metre telescope has been in operation at La Silla since early 1984, and is on indefinite loan to ESO from the Max Planck Society ( or MPG). Telescope time is shared between MPG and ESO observing programmes, while the operation and maintenance of the telescope are ESO's responsibility. However, due to a new agreement between the Max Planck Institute for Astronomy (MPIA) and ESO, the instrument is operated by MPG until the end of September 2016. The telescope hosts three instruments: the 67-million pixel Wide Field Imager with a field of view as large as the full Moon, which has taken many amazing images of celestial objects; GROND, the Gamma-Ray Burst Optical/Near-Infrared Detector, which chases the afterglows of the most powerful explosions in the Universe, known as gamma-ray bursts; and the high-resolution spectrograph, FEROS, used to make detailed studies of stars. MPG's 2.2-metre telescope in La Silla also has a twin brother located at the Calar Alto Observatory in southern Spain.

text: During the 1840s, he had the Leviathan of Parsonstown built, a 72-inch  (6 feet/1.83 m) telescope at Birr Castle, Parsonstown, County Offaly.  The  telescope replaced a  telescope that he had built previously.He had to invent many of the techniques he used for constructing the Leviathan, both because its size was without precedent and because earlier telescope builders had guarded their secrets or had simply failed to publish their methods. Details of the metal, casting, grinding and polishing of the 3-ton 'speculum' were presented in 1844 at the Belfast Natural History Society. Rosse's telescope was considered a marvellous technical and architectural achievement, and images of it were circulated widely within the British commonwealth. Building of the Leviathan began in 1842 and it was first used in 1845; regular use waited another two years, due to the Great Irish Famine. It was the world's largest telescope, in terms of aperture size, until the early 20th century. Using this telescope Rosse saw and catalogued a large number of nebulae (including a number that would later be recognised as galaxies).

text: Mr. Woodruff has over 45 years experience designing optical systems for United States space program missions. He has made significant contributions to projects ranging from Skylab, Nimbus, Apollo-Soyuz, Galileo, SIRTF/Spitzer, microgravity science, the Hubble Space Telescope (HST), and Next Generation Space Telescope (NGST), Terrestrial Planet Finder (TPF), Beyond Einstein, Exo-planet detection, Kepler, as well as others. He has wide and varied experience in the definition of optical space-borne telescopes and instruments. His technical specialties are optical physic, optics design, and optical system engineering. He has served in various technical roles in optical design, system engineering, system test, and system calibration in the development of more than 20 flight hardware instruments, so one or more of his designs have been operational in space continuously for nearly 40 years. Among his accomplishments, two activities standout: 1) He helped fix the Hubble Space Telescope spherical aberration flaw and 2) He conceived and generated the optical concept and design for the Kepler mission. He is the author or co-author of well over 25 published or presented papers. He is also an Associate of Center for Astrophysics and Space Astronomy (CASA) of the University of Colorado in Boulder, CO. Recently he retired from Lockheed Martin as a Technical Fellow in the position of Chief Scientist for Optical Systems.

text: Another difficulty is that a liquid metal mirror can only be used in zenith telescopes, i.e., that look straight up, so it is not suitable for investigations where the telescope must remain pointing at the same location of inertial space (a possible exception to this rule may exist for a mercury mirror space telescope, where the effect of Earth's gravity is replaced by artificial gravity, perhaps by rotating the telescope on a very long tether, or propelling it gently forward with rockets). Only a telescope located at the North Pole or South Pole would offer a relatively static view of the sky, although the freezing point of mercury and the remoteness of the location would need to be considered. A very large telescope already exists at the South Pole, but the North Pole is located in the Arctic Ocean.

text: Closer to the visible range of the electromagnetic spectrum is the ultraviolet. The draft ISO standard on determining solar irradiances (ISO-DIS-21348) describes the ultraviolet as ranging from ~10 nm to ~400 nm. That portion closest to X-rays is often referred to as the "extreme ultraviolet" (EUV or XUV). When an EUV photon is absorbed, photoelectrons and secondary electrons are generated by ionization, much like what happens when X-rays or electron beams are absorbed by matter.

text: A Ritchey–Chrétien telescope (RCT or simply RC) is a specialized variant of the Cassegrain telescope that has a hyperbolic primary mirror and a hyperbolic secondary mirror designed to eliminate off-axis optical errors (coma). The RCT has a wider field of view free of optical errors compared to a more traditional reflecting telescope configuration. Since the mid 20th century, a majority of large professional research telescopes have been Ritchey–Chrétien configurations; some well-known examples are the Hubble Space Telescope, the Keck telescopes and the ESO Very Large Telescope.

text: A green rim is present in every sunset, but it is too thin to be seen with a naked eye.The best time to observe the green rim is about 10 minutes before sunset time. However the solar disc is too bright at that time to use magnification such as binoculars or telescopes to look directly at the Sun. Of course a telescope or binoculars image can be projected on a sheet of paper for viewing. When the Sun gets closer to the horizon, the green rim gets fainter because  of atmospheric reddening.Although a green rim is present in every sunset, and a green flash is rare because it requires a mirage to be present, it is actually more common for people to have seen a green flash than the green rim.

text: ASU is also involved with NASA in the field of space exploration. In order to meet the needs of NASA programs, ASU built the LEED Gold Certified, 298,000-square-foot Interdisciplinary Science and Technology Building IV (ISTB 4) at a cost of $110 million in 2012. The building includes space for the School of Earth and Space Exploration (SESE) and includes labs and other facilities for the Ira A. Fulton Schools of Engineering. One of the main projects at ISTB 4 includes the OSIRIS-REx Thermal Emission Spectrometer (OTES). Although ASU built the spectrometers aboard the Martian rovers Spirit and Opportunity, OTES will be the first major scientific instrument completely designed and built at ASU for a NASA space mission. Phil Christensen, the principal investigator for the Mars Global Surveyor Thermal Emission Spectrometer (TES), is a Regents' Professor at ASU. He also serves as the principal investigator for the Mars Odyssey THEMIS instruments, as well as co-investigator for the Mars Exploration Rovers. ASU scientists are responsible for the Mini-TES instruments aboard the Mars Exploration Rovers. The Center for Meteorite Studies, which is home to rare Martian meteorites and exotic fragments from space, and the Mars Space Flight Facility are both located on ASU's Tempe campus.

text: GOTO telescopes have become more popular since the 1980s as technology has improved and prices have been reduced.  With these computer-driven telescopes, the user typically enters the name of the item of interest and the mechanics of the telescope point the telescope towards that item automatically.  They have several notable advantages for amateur astronomers intent on research.  For example, GOTO telescopes tend to be faster for locating items of interest than star hopping, allowing more time for studying of the object.  GOTO also allows manufacturers to add equatorial tracking to mechanically simpler alt-azimuth telescope mounts, allowing them to produce an overall less expensive product. GOTO telescopes usually have to be calibrated using alignment stars in order to provide accurate tracking and positioning. However, several telescope manufacturers have recently developed telescope systems that are calibrated with the use of built-in GPS, decreasing the time it takes to set up a telescope at the start of an observing session.

text: Each Keck Observatory telescope sits on an altazimuth mount. Most current 8–10 m class telescopes use altazimuth designs due to the reduced structural requirements compared to older equatorial designs. This mounting style provides the greatest strength and stiffness for the least amount of steel, which, for Keck Observatory, totals about 270 tons per telescope. The total weight of each telescope is more than 300 tons. Two of the proposed designs for the next generation 30 and 40 m telescopes use the same basic technology pioneered at Keck Observatory, a hexagonal mirror array coupled with an altazimuth mounting.

text: The telescope was designed from the start to be operated in real time, rather than by remote control. This required that it would be launched into a geosynchronous orbit – that is, one with a period equal to one sidereal day of 23h 56m. A satellite in such an orbit remains visible from a given point on the Earth's surface for many hours at a time, and can thus transmit to a single ground station for a long period of time. Most space observatories in Earth orbit, such as the Hubble Space Telescope, are in a low orbit in which they spend most of their time operating autonomously because only a small fraction of the Earth's surface can see them at a given time. Hubble, for example, orbits the Earth at an altitude of approximately 600 km, while a geosynchronous orbit has an average altitude of 36,000 km.

text: Newton's second telescope was made in 1671; it had a mirror of 2 inches diameter and a focal length of between 6.25" and 6.3".  He made two mirrors and chose the best one for the telescope.  He did not keep this telescope long, but presented it to the Royal Society for examination.  An account of this telescope just after its presentation in December 1671 described it as being about 7 inches long and about 2.25 inches in diameter.  The image was viewed through a hole in the side of the tube "about the size of a great pins head".  The tube was one piece and the mirror was moved up from the bottom in order to focus it. It was mounted on a ball and socket mount. This second telescope stayed with the society and by 1731 it had disintegrated to the point of only the two metal mirrors remaining.  It then subsequently disappeared.  It is certain that this is not the telescope that the Royal Society now hold in their possession as this mirror contained silver and the third telescope mirror contains no silver but has the addition of arsenic. This was something which Newton proposed as an improvement on his second telescope mirror as he found that the metal was too soft due to the silver.

text: Hubble is the only telescope designed to be serviced in space by astronauts.  After launch by  in 1990, four subsequent Space Shuttle missions repaired, upgraded, and replaced systems on the telescope, including all five of the main instruments.  A fifth mission was canceled on safety grounds following the Columbia disaster (2003). However, after spirited public discussion, NASA administrator Mike Griffin approved one final servicing mission, completed in 2009. The telescope is operating , and could last until 2030–2040. Its scientific successor, the James Webb Space Telescope (JWST), is scheduled for launch in 2018.

text: The region of the spectrum where a particular observed electromagnetic radiation falls, is reference frame-dependent (due to the Doppler shift for light), so EM radiation that one observer would say is in one region of the spectrum could appear to an observer moving at a substantial fraction of the speed of light with respect to the first to be in another part of the spectrum. For example, consider the cosmic microwave background. It was produced, when matter and radiation decoupled, by the de-excitation of hydrogen atoms to the ground state. These photons were from Lyman series transitions, putting them in the ultraviolet (UV) part of the electromagnetic spectrum. Now this radiation has undergone enough cosmological red shift to put it into the microwave region of the spectrum for observers moving slowly (compared to the speed of light) with respect to the cosmos.

text: Evans took up supernova hunting around 1955, but his first adequate instrument was a 10-inch (25 cm) Newtonian telescope he had assembled only about 1968. He made his first official supernova discovery in 1981 and found nine more before using larger telescopes. While living in Coonabarabran, New South Wales he used his own 16 inch (40 cm) telescope. From early 1995 to mid-1997 he also had limited access to the Siding Spring  Telescope at Siding Spring Observatory (he was allocated about 110 nights, half of which were suitable for observing), resulting in about 10,000 galaxy observations, another three visual supernovae discoveries, and an additional four supernovae spotted on photographs made at the observatory.

text: The Catalina Real-Time Transient Survey is a collaboration using three telescopes looking for optical transients.  The same telescopes are used as in the Catalina Sky Survey. They are Mt. Lemmon Survey, Catalina Sky Survey, and Siding Spring Survey.  When transients are detected they are alerted on a short time scale so that others can observe the event as well using  VOEventNet and SkyAlert.  It has detected supernovae, cataclysmic variables, blazars, active galactic nuclei and flares.

text: COAST, the Cambridge Optical Aperture Synthesis Telescope, is a multi-element optical astronomical interferometer with baselines of up to 100 metres, which uses aperture synthesis to observe stars with angular resolution as high as one thousandth of one arcsecond (producing images with much higher resolution than can be obtained using individual telescopes such as the Hubble Space Telescope). The principal limitation is that COAST can only image bright stars. COAST was the first long-baseline interferometer to obtain high-resolution images of the surfaces of stars other than our sun (although the surfaces of other stars had previously been imaged at lower resolution using Aperture Masking Interferometry on the William Herschel Telescope).

text: In MASINT, the active signal source can be anywhere in the electromagnetic spectrum, from radio waves to X-rays, limited only by the propagation of the signal from the source. X-ray sources, for example, must be in very close proximity to the target, while lasers can illuminate a target from a high satellite orbit. While this discussion has emphasized the electromagnetic spectrum, there are also both active (e.g., sonar) and passive (e.g., hydrophone and microbarograph) acoustic sensors.

text: The ABS telescope images the sky at a frequency of 145 GHz (2 mm wavelength), in the microwave region of the electromagnetic spectrum, where the CMB emission is at its maximum. It is sensitive to both the intensity and polarization of the CMB. The CMB is expected to be weakly polarized, and the ABS instrument is designed to measure this very faint signal. The camera consists of 240 polarization-sensitive pixels, with two transition-edge-sensor (TES) bolometers per pixel. This TES array is cooled to a temperature of 0.3 Kelvin to reduce thermal noise in the detectors. The optics consist of two 60-cm mirrors that are kept at a temperature of 4 K.

text: There are many amateur astronomical techniques and activities associated with deep-sky objects. Some of these objects are bright enough to find and see in binoculars and small telescopes. But the faintest objects need the light-gathering power of telescopes with large objectives, and since they are invisible to the naked eye, can be hard to find. This has led to increased popularity in GoTo telescopes that can find DSOs automatically, and large reflecting telescopes, such as Dobsonian style telescopes, with wide fields of view well suited for such observing. Observing faint objects needs dark skies, so these relatively portable types of telescopes also lend themselves to the majority of amateurs who need to travel outside light polluted urban locations. To cut down light pollution and enhance contrast observers employ "nebular filters" designed to admit certain wavelength and block others.

text: The scientific instruments consisted of an ion chamber and Geiger-Müller tube to measure total radiation flux, a proportional radiation counter telescope to measure high energy radiation, a scintillation counter to monitor low-energy radiation, a scintillation spectrometer to study the Earth's (and possible lunar) radiation belts, a VLF receiver for natural radio waves, a transponder to study electron density, and part of the flux-gate and search coil magnetometers mounted on the instrument platform. A plasma probe was mounted on the sphere to measure energy and momentum distribution of protons above a few kilovolts to study the radiation effect of solar flares. The micrometeorite detector and sun scanner were mounted on the sphere as well. The only difference between Pioneer P-31 and the earlier Pioneer P-30 was the addition of a solid state detector sensitive to low energy protons on the satellite and an STL-designed rubidium frequency standard experiment placed on a pod attached to the booster. The total mass of the science package including electronics and power supply was roughly 60 kg. Total cost of the mission was estimated at 9 - 10 million dollars.

text: Regular orbital boosts are also needed by the Hubble Space Telescope, though on a longer time scale, due to its much higher altitude. However, orbital decay is also a limiting factor to the length of time the Hubble can go without a maintenance rendezvous, the most recent performed successfully by STS-125, with space shuttle Atlantis launching May 11, 2009, though newer telescopes are in much higher orbits or in some cases in solar orbit, so orbital boosting may not be needed.

text: Already as a student was Rubens fascinated by electromagnetic radiation as theoretically described by Maxwell and experimentally demonstrated by Hertz. Through the influence of Kundt he had become interested in understanding the optical properties of different materials. In his doctoral work he showed that reflection of light increases with increasing wavelengths into the infrared region. As a related result he could present an experimental verification of Maxwell's theory for electromagnetic waves in different media. This effort also turned into a demonstration of the validity of these equations for infrared radiation. Rubens succeeded in this for wavelengths up to 10 μm.

text: In 1946, a technique called astronomical interferometry was developed. Astronomical radio interferometers usually consist either of arrays of parabolic dishes or two-dimensional arrays of omni-directional antennas. All of the telescopes in the array are widely separated and are usually connected together using coaxial cable, waveguide, optical fiber, or other type of transmission line. Interferometry increases the total signal collected, but its primary purpose is to vastly increase the resolution through a process called Aperture synthesis. This technique works by superposing (interfering) the signal waves from the different telescopes on the principle that waves that coincide with the same phase will add to each other while two waves that have opposite phases will cancel each other out. This creates a combined telescope that is equivalent in resolution (though not in sensitivity) to a single antenna whose diameter is equal to the spacing of the antennas furthest apart in the array.

text: Cutbacks in funding hit Canada's premier astronomical research organization the Herzberg Institute of Astrophysics hard. Money could not be found to resurface the Algonquin Park Radio Telescope and it along with the solar telescope near Ottawa were closed in 1986. However that same year, the HIA did establish the Canadian Astronomy Data Centre (CADC) which created special software for the archiving of astronomical date. In 1987, the HAI took a 25 percent stake in the 15-m James Clerk Maxwell Telescope (submillimetre radio) and in the nineties a 15 percent stake in the optical 8 metre Gemini Telescope, which became operational in 1999. Headquarters for the HIA moved from Ottawa to Victoria in 1995. In the 21st century, the Institute designed instruments for its international telescope programme, including the Gemini multi-object spectrograph, the JCMT auto-correlation spectrometer and imaging system and the CFHT adaptive optics bonnette. Of note is the initiation of the CFHT Legacy Survey in 2003. Using the telescope's wide field Megacam the survey consists of three studies, "Very Wide", "Wide", and "Deep", and investigates a number of phenomena including the nature of dark matter and dark energy. The University of Calgary is participating in the development of the software to be used for data acquisition and image production at the Atacama Large Millimeter Array Telescope under construction in the Atacama Desert in Chile. First light is expected in 2011.

text: Photoacoustic spectroscopy is the measurement of the effect of absorbed electromagnetic energy (particularly of light) on matter by means of acoustic detection. The discovery of the photoacoustic effect dates to 1880 when Alexander Graham Bell showed that thin discs emitted sound when exposed to a beam of sunlight that was rapidly interrupted with a rotating slotted disk. The absorbed energy from the light causes local heating and through thermal expansion a pressure wave or sound. Later Bell showed that materials exposed to the non-visible portions of the solar spectrum (i.e., the infrared and the ultraviolet) can also produce sounds.

text: The South Pole Telescope (SPT) is a 10 meter (394 in) diameter telescope located at the Amundsen–Scott South Pole Station, Antarctica. The telescope is designed for observations in the microwave, millimeter-wave, and submillimeter-wave regions of the electromagnetic spectrum, with the particular design goal of measuring the faint, diffuse emission from the cosmic microwave background (CMB). The first major survey with the SPT–designed to find distant, massive, clusters of galaxies through their interaction with the CMB, with the goal of constraining the dark energy equation of state–was completed in October 2011.  In early 2012, a new camera was installed on the SPT with even greater sensitivity and the capability to measure the polarization of incoming light.  This camera is designed to measure the so-called "B-mode" or "curl" component of the polarized CMB, leading to constraints on the mass of the neutrino and the energy scale of inflation.

text: The Hubble Space Telescope was launched in April 1990, but gave flawed images. It had been designed at MSFC, but used a primary mirror that had spherical aberration due to incorrect grinding and polishing by the contractor. The defect was found when the telescope was in orbit. The design was such that repairs were possible, and three maintenance missions were flown in Shuttles during the 1990s. Another servicing mission (STS-109) was flown on March 1, 2002. Each mission resulted in considerable improvements, with the images receiving worldwide attention from astronomers as well as the public.

text: None of the three telescopes was constructed, although several design studies were carried out and some scale models were made. This was partly due to the changing political climate over the time (the period was from a Labour Party government under Harold Wilson to a Conservative Party one under Margaret Thatcher), and partly to the financial constraints of astronomical research in the UK at the time. Also, at a vital time, it became necessary to upgrade the Lovell Telescope to the Mark IA, which subsequently overran in terms of cost.

text: The range of frequencies in the electromagnetic spectrum that makes up the radio spectrum is very large. This means that the types of antennas that are used as radio telescopes vary widely in design, size, and configuration. At wavelengths of 30 meters to 3 meters (10 MHz - 100 MHz), they are generally either directional antenna arrays similar to "TV antennas" or large stationary reflectors with moveable focal points. Since the wavelengths being observed with these types of antennas are so long, the "reflector" surfaces can be constructed from coarse wire mesh such as chicken wire. At shorter wavelengths parabolic "dish" antennas predominate. The angular resolution of a dish antenna is determined by the ratio of the diameter of the dish to the wavelength of the radio waves being observed. This dictates the dish size a radio telescope needs for a useful resolution. Radio telescopes that operate at wavelengths of 3 meters to 30 cm (100 MHz to 1 GHz) are usually well over 100 meters in diameter. Telescopes working at wavelengths shorter than 30 cm (above 1 GHz) range in size from 3 to 90 meters in diameter.

Radio telescopes that operate at wavelengths of 3 meters to 30 cm (100 MHz to 1 GHz) are usually well over 100 meters in diameter. Telescopes working at wavelengths shorter than 30 cm (above 1 GHz) range in size from 3 to 90 meters in diameter.

text: In 2000, astronomers began considering the potential of telescopes larger than 20 meters in diameter. Two technologies were considered; segmented mirrors like that of the Keck Observatory and the use of a group of 8-meter mirrors mounted to form a single unit. The US National Academy of Sciences made a suggestion that a 30-meter telescope should be the focus of US astronomy interests and recommended it to be built within the decade. The University of California, along with Caltech began development of a 30-meter telescope that same year. The California Extremely Large Telescope (CELT) began development along with the Giant Magellan Telescope, the Giant Segmented Mirror Telescope (GSMT) and the Very Large Optical Telescope (VLOT). These studies would eventually become the Thirty Meter Telescope. The TMT would have nine times the collecting area of the older Keck telescope using slightly smaller mirror segments in a vastly larger group. Another telescope of a large diameter in the works is the European Extremely Large Telescope (E-ELT) being built in northern Chile.

text: The completion of all the major objectives, as well as some that were not considered vital, upgraded the telescope to its most technologically advanced state since its launch nineteen years ago, and made it more powerful than ever. The upgrades will also help Hubble to see deeper into the universe, and farther into the past, closer to the time of the Big Bang. Hubble's importance to science is not just seen in the dramatic images it provides, but also in the volume of work it has generated – an average of fourteen scientific articles are published each week based on data gathered from the telescope. Officially, the upgrades should extend Hubble's life through 2014, but Hubble Space Telescope Senior Scientist David Leckrone noted prior to the mission that if all of the mission's objectives were successful, the telescope could easily last longer than that. The next large telescope scheduled to be launched is the James Webb Space Telescope in 2018, which is infrared-only, so to have Hubble, which has ultraviolet, visible, and near-infrared capabilities, still operational after 2018 would be of great benefit to the scientific community.

text: In the earliest uses of lenses, chromatic aberration was reduced by increasing the focal length of the lens where possible.  For example, this  could result in extremely long telescopes such as the very long aerial telescopes of the 17th century. Isaac Newton's theories about white light being composed of a spectrum of colors led him to the conclusion that uneven refraction of light caused chromatic aberration (leading him to build the first reflecting telescope, his Newtonian telescope, in 1668).

text: Electromagnetic waves are typically described by any of the following three physical properties: the frequency f, wavelength λ, or photon energy E. Frequencies observed in astronomy range from  (1 GeV gamma rays) down to the local plasma frequency of the ionized interstellar medium (~1 kHz). Wavelength is inversely proportional to the wave frequency, so gamma rays have very short wavelengths that are fractions of the size of atoms, where as wavelengths on the opposite end of the spectrum can be as long as the universe. Photon energy is directly proportional to the wave frequency, so gamma ray photons have the highest energy (around a billion electron volts), while radio wave photons have very low energy (around a femtoelectronvolt). These relations are illustrated by the following equations:

text: In 2011 a dedicated search for suitable KBOs using ground telescopes was started by mission scientists. Large ground telescopes with wide-field cameras, notably the twin 6.5-meter Magellan Telescopes in Chile, the 8.2-meter Subaru Observatory in Hawaii, and the Canada–France–Hawaii Telescope were used to search for potential targets. Through the citizen-science project, the public helped to scan telescopic images for possible suitable mission candidates by participating in the Ice Hunters project. The ground-based search resulted in the discovery of about 143 KBOs of potential interest, but none of these were close enough to the flight path of New Horizons. Only the Hubble Space Telescope was deemed likely to find a suitable target in time for a successful KBO mission. On June 16, 2014, time on Hubble was granted. Hubble has a much greater ability to find suitable KBOs than ground telescopes. The probability that a target for New Horizons would be found was estimated beforehand at about 95%.

text: In his Ultra high frequency (UHF) experiments, Hertz transmitted and received radio waves over short distances and showed that the properties of radio waves were consistent with Maxwell’s electromagnetic theory. He demonstrated that radio radiation had all the properties of waves (now called electromagnetic radiation), and discovered that the electromagnetic equations could be reformulated into a partial differential equation called the wave equation.

text: Type I diamond has nitrogen (N) atoms as the main impurity, at a concentration of up to 1%. If the N atoms are in pairs or larger aggregates, they do not affect the diamond's color; these are Type Ia. About 98% of gem diamonds are type Ia: these diamonds belong to the Cape series, named after the diamond-rich region formerly known as Cape Province in South Africa, whose deposits are largely Type Ia. If the nitrogen atoms are dispersed throughout the crystal in isolated sites (not paired or grouped), they give the stone an intense yellow or occasionally brown tint (type Ib); the rare canary diamonds belong to this type, which represents only ~0.1% of known natural diamonds. Synthetic diamond containing nitrogen is usually of type Ib. Type Ia and Ib diamonds absorb in both the infrared and ultraviolet region of the electromagnetic spectrum, from 320 nm. They also have a characteristic fluorescence and visible absorption spectrum (see Optical properties).

text: In 1891, Patrick Alexander ordered the telescope from the well-known Victorian telescope makers Thomas and Howard Grubb of Dublin with all the usual fittings associated with a professional instrument of the time. It is not entirely clear where the telescope was first installed, accounts vary. It is probable that the telescope was first erected at one of Patrick Alexander's several private workshops in Bath: either 'DeMontalat Wood' or 'The Mount'. The telescope was a substantial instrument, which together with its mounting, must have weighed several tons. The telescope was fully equipped for astronomical observations and Patrick became a fellow member of the Royal Astronomical Society up until 1921. Although he enjoyed showing his telescope to friends and distinguished visitors, any interest he had in astronomy was overshadowed by his other aviation related passions — especially ballooning; the telescope was probably a scientific toy. Barry Bellinger suggests that the telescope was used to track pilot balloons released into the air, before releasing any main balloons; however, a telescope of this size and type seems ill-suited to such a task.

text: Hercules has no first or second magnitude stars. However, it does have several stars above magnitude 4. Alpha Herculis, traditionally called Rasalgethi, is a triple star system, partly resolvable in small amateur telescopes, 359 light-years from Earth. The primary is an irregular variable star; it is a bright giant with a minimum magnitude of 4 and a maximum magnitude of 3. It has a diameter of roughly 400 solar diameters. The secondary, a spectroscopic binary that orbits the primary every 3600 years, is a blue-green hued star of magnitude 5.6. Its common name means "the kneeler's head". Beta Herculis, also called Kornephoros, is the brightest star in Hercules. It is a yellow giant of magnitude 2.8, 148 light-years from Earth. Its traditional name means "club-bearer". deltoide 5512 is a double star divisible in small amateur telescopes. The primary is a blue-white star of magnitude 3.1, and is 78 light-years from Earth. The optical companion is of magnitude 8.2. Gamma Herculis is also a double star divisible in small amateur telescopes. The primary is a white giant of magnitude 3.8, 195 light-years from Earth. The optical companion, widely separated, is 10th magnitude. Zeta Herculis is a binary star that is becoming divisible in medium-aperture amateur telescopes, as the components widen to their peak in 2025. The system, 35 light-years from Earth, has a period of 34.5 years. The primary is a yellow-tinged star of magnitude 2.9 and the secondary is an orange star of magnitude 5.7.

text: Unusually for a radio telescope, the primary reflector is an off-axis segment of a paraboloid. This is the same design used in familiar home satellite television (e.g., DirecTV) dishes. The asymmetric reflector allows the telescope's focal point and feed horn to be located at the side of the dish, so that it and its retractable support boom do not obstruct the incoming radio waves, as occurs in conventional radio telescope designs with the feed located on the telescope's beam axis.

text: Pip begins spying on her new neighbors with her telescope, and taking pictures of the Marshall's around town. She tries with her telescope to look inside the shed to discover the cause of the strange noises but fails. She also sees Sally's teenage brother "Wayne Marshall" dance stripping in his room by himself with a biker helmet on his head that he never takes off while playing rock music from his stereo. The next day Pip walks by the Marshalls' house and begins throwing tennis balls over the fence. After throwing several balls over the fence "Granny Marshall", who seems to be floating on air, gives Pip the ball back. Pip walks around to the front of the house then walks through the gate into the Marshall's back yard. Pip sees the huge tomatoes growing in bushes alongside the fence and takes one just as Sally comes outside. Before Sally talks to Pip she gives her dad a full glass of lemonade that he drinks in a matter of seconds. When Sally takes the glass back she says "Hi" to Pip, and they have a short conversation. Sally asks Pip if she would like to hang out but Pip says she can't, but maybe another time. Pip then leaves with the tomato in hand. Meanwhile Ben is at the playground because Pip is mad that he kissed her. He then gives Rhonnie the pictures she took in exchange for Pip's walkman in hopes that she will forgive him.

text: Radio waves were first identified in German physicist Heinrich Hertz's 1887 series of experiments to prove James Clerk Maxwell's electromagnetic theory.  Hertz used spark-excited dipole antennas to generate the waves and micrometer spark gaps attached to dipole and loop antennas to detect them.  These primitive devices are more accurately described as radio wave sensors, not "receivers", as they could only detect radio waves within about 100 feet of the transmitter, and were not used to attempt communication but were instead used as part of an experiment to verify a theoretical proof.

text: The Suffa RT-70 radio telescope is an RT-70 radio telescope under construction at the Suffa Radio Observatory on the Suffa plateau, Uzbekistan.  Construction began in the late 80's, but was put on hold when the USSR fell.  As of 2008, construction had resumed, with an updated emphasis on millimeter-wave band observations at 100–300 GHz. Construction was scheduled to be completed in 2012, but information on the current status of the observatory is spotty as of 2013.

text: In 2009, NASA's Kepler spacecraft was completing the last of tests on its photometer, the instrument it uses to detect transit events, in which a planet crosses in front of and dims its host star for a brief and roughly regular period of time. In this last test, Kepler observed  stars in the Kepler Input Catalog, including Kepler-7; the preliminary light curves were sent to the Kepler science team for analysis, who chose obvious planetary companions from the bunch for follow-up at observatories. Kepler-7 was not one of these original candidates. After a resting period of 1.3 days, Kepler began a nonstop 33.5-day period in which it observed  targets uninterrupted until June 15, 2009, when the collected data was downloaded and tested for false positives. Kepler-7's candidate was not found to be one of these false positives, such as an eclipsing binary star that may generate a light curve that mimics that of transiting planetary companions. Kepler-7 was then observed using Doppler spectroscopy using the Fibre-fed Echelle Spectrograph at the Canary Islands' Nordic Optical Telescope for ten nights in October 2009, taken with respect to the star HD 182488 to compensate for possible telescope error. Speckle imaging of the star was taken at WIYN Observatory in Arizona to check for close companions; when none were found, the High Resolution Echelle Spectrometer instrument at the W.M. Keck Observatory on Hawaii, the Harlan J. Smith Telescope at the McDonald Observatory in Texas, the PRISM camera at the Lowell Observatory, and the Faulkes Telescope North at the Haleakala Observatory on Maui were also used to analyze Doppler spectroscopy of the planetary candidate. The radial velocity observations confirmed that a planetary body was responsible for the dips observed in Kepler-7's light curve, thus confirming it as a planet.

text: As is the case for visible light telescopes, space is the ideal place for infrared telescopes. In space, images from infrared telescopes can achieve higher resolution, as they do not suffer from blurring caused by the Earth's atmosphere, and are also free from absorption caused by the Earth's atmosphere. Current infrared telescopes in space include the Herschel Space Observatory, the Spitzer Space Telescope, and the Wide-field Infrared Survey Explorer. Since putting telescopes in orbit is expensive, there are also airborne observatories, such as the Stratospheric Observatory for Infrared Astronomy and the Kuiper Airborne Observatory. These observatories place telescopes above most, but not all, of the atmosphere, which means there is absorption of infrared light from space by water vapor in the atmosphere.

text: When initial assessments were being made for the feasibility of restoring the observatory, both the telescope and observatory were in a poor condition as a result of years of neglect and an arson attempt by some local children. The telescope is made predominantly from brass and thus suffered minimal corrosion and damage. Most importantly the lens of the telescope survived unscathed allowing for restoration. This was carried out at first by several dedicated parents and governors of the school, amongst them Syd Little. Soon after the basic restoration ideas were raised for a larger project allowing the teaching of astronomy on a larger scale. After getting clearance from the original owners of the telescope to go ahead with the project, Rossall was given funds from the Lawrence House Trust, an educational charity, to go forward with their plans. The centre had an official opening on 26 September 2006 with Old Rossallian and former Astronomer Royal Sir Francis Graham Smith in attendance. The centre's motto is 'Astronomy For All' meaning that it offers courses to Rossall Students but also at a small cost to the general public. Courses also range from beginner to advanced to ensure that anybody who wishes to study Astronomy can do so.

text: Huygens eyepieces consist of two plano-convex lenses with the plane sides towards the eye separated by an air gap. The lenses are called the eye lens and the field lens. The focal plane is located between the two lenses. It was invented by Christiaan Huygens in the late 1660s and was the first compound (multi-lens) eyepiece. Huygens discovered that two air spaced lenses can be used to make an eyepiece with zero transverse chromatic aberration. These eyepieces work well with the very long focal length telescopes (in Huygens day they were used with single element long focal length non-achromatic refracting telescopes, including very long focal length aerial telescopes). This optical design is now considered obsolete since with today's shorter focal length telescopes the eyepiece suffers from short eye relief, high image distortion, chromatic aberration, and a very narrow apparent field of view. Since these eyepieces are cheap to make they can often be found on inexpensive telescopes and microscopes. Because Huygens eyepieces do not contain cement to hold the lens elements, telescope users sometimes use these eyepieces in the role of "solar projection", i.e. projecting an image of the Sun onto a screen. Other cemented eyepieces can be damaged by the intense, concentrated light of the Sun.

text: Most modern professional telescopes use a guide star. An autoguider is pointed to a sufficiently luminous star that lies near the object being observed and, if the pointing begins to drift, the error can be detected and the movement corrected. This is most accurate when the corrections are applied by a computer, but amateur telescopes often have manual correction (requiring the observer to continuously follow the star by eye for the exposure period, which may be a significant length of time).

text: Submillimetre astronomy or submillimeter astronomy (see spelling differences) is the branch of observational astronomy that is conducted at submillimetre wavelengths (i.e., terahertz radiation) of the electromagnetic spectrum. Astronomers place the submillimetre waveband between the far-infrared and microwave wavebands, typically taken to be between a few hundred micrometres and a millimetre. It is still common in submillimetre astronomy to quote wavelengths in 'microns', the old name for micrometre.

text: According to NASA, the Roentgensatellit (ROSAT) was a joint German, U.S. and British X-ray astrophysics project. ROSAT carried a German-built imaging X-ray Telescope (XRT) with three focal plane instruments: two German Position Sensitive Proportional Counters (PSPC) and the US-supplied High Resolution Imager (HRI). The X-ray mirror assembly was a grazing incidence four-fold nested Wolter I telescope with an 84-cm diameter aperture and 240-cm focal length. The angular resolution was less than 5 arcsecond at half energy width (the "angle within which half of the electromagnetic radiation" is focused). The XRT assembly was sensitive to X-rays between 0.1 and 2 keV (one thousand Electronvolt).

text: The NIMS instrument was sensitive to 0.7-to-5.2-micrometre wavelength IR light, overlapping the wavelength range of the SSI. The telescope associated with NIMS was all reflective (using only mirrors and no lenses) with an aperture of 229 mm. The spectrometer of NIMS used a grating to disperse the light collected by the telescope. The dispersed spectrum of light was focused on detectors of indium antimonide and silicon. The NIMS weighed 18 kilograms and used 12 watts of power on average.

text: The Large Binocular Telescope (LBT) is an optical telescope for astronomy located on  Mount Graham, in the Pinaleno Mountains of southeastern Arizona, United States.  It is a part of the Mount Graham International Observatory. The LBT is currently one of the world's most advanced optical telescopes; using two 8.4 m (27 ft) wide mirrors, with centres 14.4m apart, it has the same light-gathering ability as an 11.8 m (39 ft) wide single circular telescope and detail of a 22.8 m (75 ft) wide one. Its mirrors individually are the joint second-largest optical telescope in continental North America, behind the Hobby–Eberly Telescope in West Texas; it is also the largest monolithic, or , in an optical telescope. Strehl ratios of 60–90% in the infrared H band and 95% in the infrared M band have been achieved by the LBT.

text: Low was named to serve as facility scientist for NASA's Space Infrared Telescope Facility, later renamed the Spitzer Space Telescope. The effort had been delayed by cost overruns, until Low had an inspiration at a 1993 retreat for the project's scientists; the passive cooling technique could be used - rather than place the entire telescope in a bath of liquid helium to cool the unit to temperatures near absolute zero, the unit could be exposed to the vacuum of space to radiate most of its heat while the detectors themselves were the only components cooled using liquid helium, a design change that allowed the Spitzer project to go ahead towards its launch in 2003.  Timothy Hawarden has been recognized by NASA for the development of the passive cooling technique, which has also been included in other space probes, such as the James Webb Space Telescope, a partial successor to the Hubble Space Telescope, that will search for the oldest objects in the universe.

text: Gasholders were constructed of a variety of materials, brick, stone, concrete, steel, or wrought iron. The holder or floating vessel is the storage reservoir for the gas, and it serves the purpose of equalizing the distribution of the gas under pressure, and ensures a continuity of supply, while gas remains in the holder. They are cylindrical like an inverted beaker and work up and down in the tank. In order to maintain a true vertical position, the vessel has rollers which work on guide-rails attached to the tank sides and to the columns surrounding the holder. Gasholders may be either single or telescopic in two or more lifts. When it is made in the telescopic form, its capacity could be increased to as much as four times the capacity of the single-lift holder for equal dimensions of tank. The telescopic versions were found to be useful as they conserved ground space and capital.

text: Electron-capture dissociation (ECD) was developed in 1998 to fragment large proteins for mass spectrometric analysis. Because ECD requires a large amount of near-thermal electrons (<0.2eV), originally it was used exclusively with Fourier transform ion cyclotron resonance mass spectrometry (FTICR), the most expensive form of MS instrumentation. Less costly options such as quadrupole time-of-flight (Q-TOF), quadrupole ion trap (QIT) and linear quadrupole ion trap (QLT) instruments used the more energy-intensive collision-induced dissociation method (CID), resulting in random fragmentation of peptides and proteins. In 2004 Syka et al. announced the creation of ETD, a dissociation method similar to ECD, but using a low-cost, widely available commercial spectrometer. The first ETD experiments were run on a QLT mass spectrometer with an electrospray ionization (ESI) source.

text: The pointing of the telescope is fine tuned at the beginning of each season by using a coaligned optical telescope to observe a large number of stars covering a wide range of azimuths and elevations. A least-squares fit to the pointing errors is used to define 5 pointing parameters (offsets of the azimuth and elevation encoders, effective longitude and latitude, and the small nonperpendicularity of the azimuth and elevation axes). Because the relatively large beam of the telescope makes continuum observations of planets inconvenient, pointing is checked weekly by radio continuum observations of the limb of the sun. Although during the observing season (fall, winter, and spring) the sun transits below the elevation of most CO observations, it is the only practical astronomical source for pointing checks. At elevations used for observations, the root mean square pointing errors of the telescope were less than about 1', about 1/9 beamwidth.

text: A camera may work with the light of the visible spectrum or with other portions of the electromagnetic spectrum. A still camera is an optical device which creates a single image of an object or scene and records it on an electronic sensor or photographic film. All cameras use the same basic design: light enters an enclosed box through a converging lens/convex lens and an image is recorded on a light-sensitive medium(mainly a transition metal-halide). A shutter mechanism controls the length of time that light can enter the camera. Most photographic cameras have functions that allow a person to view the scene to be recorded, allow for a desired part of the scene to be in focus, and to control the exposure so that it is not too bright or too dim. A display, often a liquid crystal display (LCD), permits the user to view scene to be recorded and settings such as ISO speed, exposure, and shutter speed.

text: Many types of telescope fold or divert the optical path with secondary or tertiary mirrors. These may be integral part of the optical design (Newtonian telescope, Cassegrain reflector or similar types), or may simply be used to place the eyepiece or detector at a more convenient position. Telescope designs may also use specially designed additional lenses or mirrors to improve image quality over a larger field of view.

text: In 1666 Isaac Newton, based on his theories of refraction and color, perceived that the faults of the refracting telescope were due more to a lens's varying refraction of light of different colors than to a lens's imperfect shape. He concluded that light could not be refracted through a lens without causing chromatic aberrations, although he incorrectly concluded from some rough experiments that all refracting substances would diverge the prismatic colors in a constant proportion to their mean refraction. From these experiments Newton concluded that no improvement could be made in the refracting telescope. Newton's experiments with mirrors showed that they did not suffer from the chromatic errors of lenses, for all colors of light the angle of incidence reflected in a mirror was equal to the angle of reflection, so as a proof to his theories Newton set out to build a reflecting telescope. Newton completed his first telescope in 1668 and it is the earliest known functional reflecting telescope.  After much experiment, he chose an alloy (speculum metal) of tin and copper as the most suitable material for his objective  mirror. He later devised means for grinding and polishing them, but chose a spherical shape for his mirror instead of a parabola to simplify construction. He added to his reflector what is the hallmark of the design of a "Newtonian telescope", a secondary "diagonal" mirror near the primary mirror's focus to reflect the image at 90° angle to an eyepiece mounted on the side of the telescope. This unique addition allowed the image to be viewed with minimal obstruction of the objective mirror. He also made all the tube, mount, and fittings. Newton's first compact reflecting telescope had a mirror diameter of 1.3 inches and a focal ratio of f/5. With it he found that he could see the four Galilean moons of Jupiter and the crescent phase of the planet Venus. Encouraged by this success, he made a second telescope with a magnifying power of 38x which he presented to the Royal Society of London in December 1672. This type of telescope is still called a Newtonian telescope.

text: For much of the history of observational astronomy, almost all observation was performed in the visual spectrum with optical telescopes. While the Earth's atmosphere is relatively transparent in this portion of the electromagnetic spectrum, most telescope work is still dependent on seeing conditions and air transparency, and is generally restricted to the night time. The seeing conditions depend on the turbulence and thermal variations in the air. Locations that are frequently cloudy or suffer from atmospheric turbulence limit the resolution of observations. Likewise the presence of the full Moon can brighten up the sky with scattered light, hindering observation of faint objects.

text: The American astronomer and lens designer James Gilbert Baker first proposed a Cassegrain design for Bernhard Schmidt's Schmidt camera in 1940. The optical shop at Mount Wilson Observatory manufactured the first one during World War II as part of their research into optical designs for the military. As in the Schmidt camera this design uses a spherical primary mirror and a Schmidt corrector plate to correct for spherical aberration. In this Cassegrain configuration the convex secondary mirror acts as a field flattener and relays the image through the perforated primary mirror to a final focal plane located behind the primary. Some designs include additional optical elements (such as field flatteners) near the focal plane. The first large telescope to use the design was the James Gregory Telescope of 1962 at the University of St Andrews.

text: In the 1980s the aperture synthesis interferometric imaging technique was extended to visible light and infrared astronomy by the Cavendish Astrophysics Group, providing the first very high resolution images of nearby stars.  In 1995 this technique was demonstrated on an array of separate optical telescopes for the first time, allowing a further improvement in resolution, and allowing even higher resolution imaging of stellar surfaces. Software packages such as BSMEM or MIRA are used to convert the measured visibility amplitudes and closure phases into astronomical images. The same techniques have now been applied at a number of other astronomical telescope arrays, including the Navy Prototype Optical Interferometer, the Infrared Spatial Interferometer and the IOTA array. A number of other interferometers have made closure phase measurements and are expected to produce their first images soon, including the VLTI, the CHARA array and Le Coroller and Dejonghe's Hypertelescope prototype. If completed, the MRO Interferometer with up to ten movable telescopes will produce among the first higher fidelity images from a long baseline interferometer. The Navy Optical Interferometer took the first step in this direction in 1996, achieving 3-way synthesis of an image of Mizar; then a first-ever six-way synthesis of Eta Virginis in 2002; and most recently "closure phase" as a step to the first synthesized images produced by geostationary satellites.

text: NCRA has set up a unique facility for radio astronomical research using the metrewavelengths range of the radio spectrum, known as the Giant Metrewave Radio Telescope (GMRT), it is located at a site about 80 km north of Pune. GMRT consists of 30 fully steerable gigantic parabolic dishes of 45m diameter each spread over distances of up to 25 km. GMRT is one of the most challenging experimental programmes in basic sciences undertaken by Indian scientists and engineers. GMRT is a unique instrument which opens up the sky at the Metrewave range of the Electromagnetic spectrum and using the technique of Aperture synthesis allows to make high sensitive maps of the sky. The instrument is at par with other radio telescopes in the world like the VLA in terms of resolution. It compliments VLA at the metre-wavelengths.

text: CFBDSIR 1458+10 B was discovered in 2011 by Liu et al. with laser guide star (LGS) adaptive optics (AO) system of the 10 m Keck II Telescope on Mauna Kea, Hawaii, using infra-red camera NIRC2 (the observations were made on 2010 May 22 and 2010 July 8 (UT)). In 2011 Liu et al. published a paper in The Astrophysical Journal where they presented discovery of CFBDSIR 1458+10 system component B (the only discovery presented in the article). Also they presented a near-infrared (J-band) trigonometric parallax of the system, measured using WIRCam on the Canada-France-Hawaii Telescope (CFHT), Mauna Kea, in seven epochs during the 2009—2010; and spectroscopy with the X-Shooter spectrograph at the European Southern Observatory's Very Large Telescope (VLT) Unit Telescope 2 (UT2) in Chile (the observations have been performed from May 5 to July 9, 2010), that allowed to calculate the temperature (and other physical parameters) of the two brown dwarfs.

text: The UK ATC was formed in 1998 in Edinburgh from the technology departments of the Royal Observatory, Edinburgh (ROE), and the Royal Greenwich Observatory, Cambridge (RGO). Its initial "customers" were the then new Gemini Observatory, the former ROE observatories in Hawaii (the James Clerk Maxwell Telescope (JCMT) and the United Kingdom Infrared Telescope (UKIRT)), and a former RGO observatory, the Isaac Newton Group on La Palma, Canary Islands. More recently, collaboration with the European Southern Observatory (ESO) and for the James Webb Space Telescope (JWST) have gained importance. Major projects and collaborations include:

First we wanted to extend the range of our observations far back in time to the earliest days of the Universe, and this required a large increase in both sensitivity and resolution. With greater resolution we hoped that we might be able to draw radio maps of individual radio sources with sufficient detail to give some indication of the physical processes which brought them into being."

text: During the 1970s, the telescope was used in conjunction with the Mark III to develop phase stable long baseline interferometers, leading to the development of MERLIN. The telescope was used as an interferometer with the Lovell Telescope to provide more accurate positions for radio sources found from a survey done in 1972 and 1973; the position of one radio source was found to coincide with a pair of faint blue stars, and after optical observations were made it was found to be the first gravitational lens. The majority of the current observational time of the Mark II is spent either on MERLIN or VLBI observations.

text: The seven optical telescopes at Bayfordbury campus allow students to observe detailed images of objects in space. They can be equipped with a variety of research-grade CCD cameras, high resolution spectrographs or high frame-rate video cameras. Moreover, the five newest telescopes are also able to be operated remotely, and students and staff can request observations via the internet and have images taken automatically when the weather allows. The 4.5-metre radio telescope and 3-dish 115-metre baseline interferometer allow a completely different view of the universe. These are connected to 21 cm line receivers, to detect the neutral hydrogen in the galaxy and extragalactic radio sources.

text: Space telescopes such as the Hubble Space Telescope has signified a new era of detailed observations of faint objects from afar in all of the electromagnetic spectrum. This includes faint objects in the Solar system, such as Neptune. Adaptive optics technology has also allowed for detailed observations of faint objects from ground-based telescopes and this technology has been used since 1997 to obtain scientific information on Neptune and its atmosphere. These image recordings now exceed the capability of HST by far and in some instances even the Voyager images, such as Uranus. Ground-based observations are however always limited in their registration of electromagnetic waves of certain wavelengths, due to the inevitable atmospheric absorption, in particular of high energy waves.

text: Radio waves are a type of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than infrared light.  Radio waves have frequencies as high as 300 GHz to as low as 3 kHz, though some definitions describe waves above 1 or 3 GHz as microwaves, or include waves of any lower frequency. At 300 GHz, the corresponding wavelength is , and at 3 kHz is . Like all other electromagnetic waves, they travel at the speed  of light. Naturally occurring radio waves are generated by lightning, or by astronomical objects.

text: Before the advent of telescopic photography, eight moons of Saturn were discovered by direct observation using optical telescopes. Saturn's largest moon, Titan, was discovered in 1655 by Christiaan Huygens using a  objective lens on a refracting telescope of his own design. Tethys, Dione, Rhea and Iapetus (the "Sidera Lodoicea") were discovered between 1671 and 1684 by Giovanni Domenico Cassini. Mimas and Enceladus were discovered in 1789 by William Herschel. Hyperion was discovered in 1848 by W.C. Bond, G.P. Bond and William Lassell.

text: A small structure on the south side of the summit of Schultz Peak and referred to by some as a shepherd's cabin was actually built by Lowell Observatory in 1927 to house a telescope.  The site was selected by Dr. V. M. Slipher, Director of Lowell Observatory, for a pair of Bristlecone Pine trees oriented in a north-south line so that they could be cut and pressed into service as supports for the Polar Axle of the telescope.  The Polar Axle and telescopes were constructed by the Stanley Sykes of Lowell Observatory, and the cabin housing the telescope was constructed by Ramon Vilma (spelling?), a local stonemason <Personal Communication with Dr. H. L. Giclas>.  The structure had a corrugated metal roof that could be rolled off to expose the telescope for observations.  The Polar Axle was taken by truck on the then-new Weatherford Road to Schultz Saddle, then by mule to the Schultz Peak summit, and the two telescopes used there were hauled up in the same way.  The telescopes were a  reflector and a  reflector.  The observing site also had a small dormitory partially cut into the hillside east of the telescope, but only an indistinct depression remains.  From 1927 until 1932 this was the highest astronomical observing site on Planet Earth.  This distinction passed to the Swiss in 1932 when they commissioned a slightly higher observing site on the Jungfrau.  The original purpose of the site was to make spectroscopic observations of planets, stars, and nebulae to exploit the increased atmospheric transmission - especially in ultraviolet and infrared wavelengths - at high altitude.  A similar telescope and roll-off structure was constructed at the Mars Hill campus of Lowell Observatory so that spectroscopic observations made at the two sites could be compared.  The telescope at Mars Hill is still in service and now mounts a  reflector.  Today it is used by Dr. G. W. Lockwood to collect long-term data on variability of Solar Radiation and it has a fascinating history in its own right <http://www2.lowell.edu/users/wes/index.htm>.  The telescopes and Polar Axle from the Schultz Peak site still exist, and one of the bearing assemblies from the original roll-off roof has been retrieved from Schultz Peak as a possible future museum exhibit.

text: Since the atmosphere is opaque for most of the electromagnetic spectrum, only a few bands can be observed from the Earth's surface. These bands are visible – near-infrared and a portion of the radio-wave part of the spectrum. For this reason there are no X-ray or far-infrared ground-based telescopes as these have to be observed from orbit. Even if a wavelength is observable from the ground, it might still be advantageous to place a telescope on a satellite due to astronomical seeing.

text: The planet was claimed to be detected by astronomers in the Lick–Carnegie Exoplanet Survey, led by principal investigator Steven S. Vogt, professor of astronomy and astrophysics at the University of California, Santa Cruz, and co-investigator R. Paul Butler of the Carnegie Institution of Washington. The discovery was made using radial velocity measurements, combining 122 observations obtained over 11 years from the High Resolution Echelle Spectrometer (HIRES) instrument of the Keck 1 telescope with 119 measurements obtained over 4.3 years from the High Accuracy Radial Velocity Planet Searcher (HARPS) instrument of the European Southern Observatory's 3.6 m telescope at La Silla Observatory.

text: Before the invention of telescopes, events such as these that were visible to the naked eye, from within or near the Milky Way Galaxy, were very rare, and sometimes hundreds of years apart. However, such events were recorded in antiquity, such as the supernova in 1054 observed by Chinese, Japanese and Arab astronomers, and the event in 1572 known as "Tychos's Supernova" after Tycho Brahe, who studied it until it faded after two years. Even though telescopes made it possible to see more distant events, their small fields of view – typically less than 1 square degree – meant that the chances of looking in the right place at the right time were low.

text: In April 1640, Neile was elected Member of Parliament for Ripon in the Short Parliament. During the interregnum he was living at White Waltham, Berkshire where he studied astronomy and built telescopes. Sir Christopher Wren was using Neile's telescope at White Waltham in 1655 and in 1658 Neile gave a 35-foot telescope to Gresham College. He was one of the twelve founder members of the Royal Society and in 1661 the Society "desired him to continue his employment of the artificer for making glasses for perspectives".

text: The technique was developed in the 1960s, but was largely replaced in the 1970s and 1980s by spectroscopic redshifts, using spectroscopy to observe the frequency (or wavelength) of characteristic spectral lines, and measure the shift of these lines from their laboratory positions.  The photometric redshift technique has come back into mainstream use since 2000, as a result of large sky surveys conducted in the late 1990s and 2000s which have detected a large number of faint high-redshift objects, and telescope time limitations mean that only a small fraction of these can be observed by spectroscopy.

text: Hewitt was born in Washington, D.C. on September 4, 1958 to parents Warren E. Hewitt, a retired international lawyer from the State Department, and Gertrud (Graedel) Hewitt.  She attended Bryn Mawr College where she graduated magna cum laude with a degree in economics in 1980.  Hewitt took an astronomy class her sophomore year, which sparked her interest in science.  She attended the Massachusetts Institute of Technology for graduate school.  During her graduate studies, she began studying gravitational lensing using the Very Large Array radio telescope.  She preferred using a radio telescope, as gravitational lenses emit a large amounts of radio waves, making them easier to discern with a radio telescope than with an optical telescope.  Hewitt obtained a Ph.D. in physics in 1986.  Some sources erroneously state that she received her Ph. D. in 1988.

text: The music video was directed by Chris Applebaum. The main premise of the video was centered around the conclusion of the movie A Walk to Remember. It showed Moore in Heaven and Shane West looking through a telescope at her. The movie featured the couple stargazing and Moore's character Jamie Sullivan believed that when she would look through a telescope at the stars she can see into Heaven. Landon Carter (West's character) looks through the telescope and can see a now passed Jamie in Heaven. As the video comes to a climax, there is an explosion and stars shoot from behind Moore. The video also shows West looking at random video clips of him and Moore. The home video was the summer that Moore and West's characters spent together before she died. The video was not a huge success on MTV like her prior video "Crush". The music video is included on A Walk to Remember DVD as an extra content. It was also included as a multi-media track on the 2003 special expanded edition of the film's soundtrack. However, the song is not yet included in her Vevo channel.

text: Thaddeus and his colleagues designed a radio telescope custom-built for the task of mapping the entire Milky Way in CO. The 1.2 meter Millimeter-Wave Telescope was designed with a relatively small dish and consequently a relatively large beamwidth of about 1/8 degree, which can be likened to a wide-angle lens. With this new instrument, it suddenly became possible to map large stretches of sky in relatively small amounts of time. The telescope is nicknamed "The Mini" because of its unusually small size. Together, "The Mini" and its twin in Chile have obtained what is by far the most extensive, uniform, and widely used Galactic survey of interstellar carbon monoxide (CO).

text: NASA officials decided to move up part of the servicing mission that had been scheduled for June 2000 after three of the telescope's six gyroscopes failed. Three gyroscopes must be working to meet the telescope's very precise pointing requirements, and the telescope's flight rules dictated that NASA consider a "call-up" mission before a fourth gyroscope failed. Four new gyros were installed during the first servicing mission (STS-61) in December 1993 and all six gyros were working during the second servicing mission (STS-82) in February 1997. Since then, a gyro failed in 1997, another in 1998 and a third in 1999. The Hubble team believed they understood the cause of the failures, although they could not be certain until the gyros were returned from space. Having fewer than three working gyroscopes would have precluded science observations, although the telescope would have remained safely in orbit until a servicing crew arrived.

text: Noise-equivalent temperature (NET) is a measure of the sensitivity of a detector of thermal radiation in the infrared, terahertz or microwave portions of the electromagnetic spectrum.   It is the amount of incident signal temperature that would be needed to match the internal noise of the detector such that the signal-to-noise ratio is equal to one.  Often the spectrum of the NET is reported as a temperature per root bandwidth.  A detector that measures power is often interested in the analogous noise-equivalent power (NEP).  If a relation between intensity and temperature is well defined over the pass band, as in the case of a blackbody, then the NET simply scales with the NEP.

text: In the early 1970s, O'Leary and other gay liberation activists did not actively include all transsexuals and transvestites in proposed gay rights legislation, largely due to the belief that this would make basic legislation too difficult to pass at the time. O'Leary later regretted her stance against the drag queens attending in 1973: "Looking back, I find this so embarrassing because my views have changed so much since then. I would never pick on a transvestite now." "It was horrible. How could I work to exclude transvestites and at the same time criticize the feminists who were doing their best back in those days to exclude lesbians?"

text: Between 1886 and 1889 Hertz would conduct a series of experiments that would prove the effects he was observing were results of Maxwell's predicted electromagnetic waves. Starting in November 1887 with his paper "On Electromagnetic Effects Produced by Electrical Disturbances in Insulators", Hertz would send a series of papers to Helmholtz at the Berlin Academy, including papers in 1888 that showed transverse free space electromagnetic waves traveling at a finite speed over a distance. In the apparatus Hertz used, the electric and magnetic fields would radiate away from the wires as transverse waves. Hertz had positioned the oscillator about 12 meters from a zinc reflecting plate to produce standing waves. Each wave was about 4 meters long. Using the ring detector, he recorded how the wave's magnitude and component direction varied. Hertz measured Maxwell's waves and demonstrated that the velocity of these waves was equal to the velocity of light. The electric field intensity, polarity and reflection of the waves were also measured by Hertz. These experiments established that light and these waves were both a form of electromagnetic radiation obeying the Maxwell equations. Hertz also described the "Hertzian cone", a type of wave-front propagation through various media.

text: The Hubble Space Telescope (HST) is a space telescope that was launched into low Earth orbit in 1990, and remains in operation. Although not the first space telescope, Hubble is one of the largest and most versatile, and is well known as both a vital research tool and a public relations boon for astronomy. The HST is named after the astronomer Edwin Hubble, and is one of NASA's Great Observatories, along with the Compton Gamma Ray Observatory, the Chandra X-ray Observatory, and the Spitzer Space Telescope.

text: Born in Melbourne, Australia, Cowan completed his studies in Sydney. His first published works were Nine Poems (Mauritius, 1964) and A Rambling Man (Sydney, 1966). In the 1960s he travelled and worked in Mauritius, Vancouver, New York, Paris and London. For some years he lived in Marrakech, and in Libya, studying the Berber and Tuareg peoples. Returning to Australia in 1973, he decided to view his homeland as a foreign country. He made journeys throughout the continent, sometimes on horseback, exploring early European culture and its imprint on the land.  This led to a succession of books, The Mountain Men, The River People, and Starlight's Trail.

text: The Lovell Telescope  is a radio telescope at Jodrell Bank Observatory, near Goostrey, Cheshire in the north-west of England. When construction was finished in 1957, the telescope was the largest steerable dish radio telescope in the world at 76.2 m (250 ft) in diameter;it is now the third largest, after the Green Bank telescope in West Virginia, United States, and the Effelsberg telescope in Germany.It was originally known as the "250 ft telescope" or the Radio Telescope at Jodrell Bank, before becoming the Mark I telescope around 1961 when future telescopes (the Mark II, III, and IV) were being discussed. It was renamed to the Lovell Telescope in 1987 after Sir Bernard Lovell, and became a Grade I listed building in 1988. The telescope forms part of the MERLIN and European VLBI Network arrays of radio telescopes.

text: Radio – transmission of signals by modulation of electromagnetic waves with frequencies below those of visible light. Electromagnetic radiation travels by means of oscillating electromagnetic fields that pass through the air and the vacuum of space. Information is carried by systematically changing (modulating) some property of the radiated waves, such as amplitude, frequency, phase, or pulse width. When radio waves pass an electrical conductor, the oscillating fields induce an alternating current in the conductor. This can be detected and transformed into sound or other signals that carry information.

text: A duplex communication system is a system composed of two connected parties or devices which can communicate with one another in both directions. The term duplex is used when describing communication between two parties or devices. Duplex systems are employed in nearly all communications networks, either to allow for a communication "two-way street" between two connected parties or to provide a "reverse path" for the monitoring and remote adjustment of equipment in the field.An Antenna is basically a small length of a qwert conductor that is used to radiate or receive electromagnetic waves.It acts as a conversion device.At the transmitting end it converts high frequency current into electromagnetic waves.At the receiving end it transforms electromagnetic waves into electrical signals that is fed into the input of the receiver. several types of antenna are used in communication.

text: The sensitivity of Earth-based infrared telescopes is significantly limited by water vapor in the atmosphere, which absorbs a portion of the infrared radiation arriving from space outside of selected atmospheric windows. This limitation can be partially alleviated by placing the telescope observatory at a high altitude, or by carrying the telescope aloft with a balloon or an aircraft. Space telescopes do not suffer from this handicap, and so outer space is considered the ideal location for infrared astronomy.

text: There have been three main phases in the observation and exploration of Saturn. The first era was ancient observations (such as with the naked eye), before the invention of the modern telescopes. Starting in the 17th century progressively more advanced telescopic observations from Earth have been made. The other type is visitation by spacecraft, either by orbiting or flyby. In the 21st century observations continue from the Earth (or Earth-orbiting observatories) and from the Cassini orbiter at Saturn.

text: The phase velocity of an electromagnetic wave, when traveling through a medium, can routinely exceed c, the vacuum velocity of light. For example, this occurs in most glasses at X-ray frequencies. However, the phase velocity of a wave corresponds to the propagation speed of a theoretical single-frequency (purely monochromatic) component of the wave at that frequency. Such a wave component must be infinite in extent and of constant amplitude (otherwise it is not truly monochromatic), and so cannot convey any information.Thus a phase velocity above c does not imply the propagation of signals with a velocity above c.

text: Two additional telescopes were added in Phase 2 of the project, along with their radio links to Jodrell Bank. While it was originally proposed that one of the telescopes would be sited at Jodrell Bank and the other at Darnhall, the pair were finally sited at Pickmere (also known as Tabley) and Darnhall. The two telescopes were the same as that at Knockin. Construction on both telescopes started on 9 April 1979, and was completed by 31 October 1979. The Pickmere telescope was connected into MTRLI for the first time on 20 July 1980, followed by the Darnhall telescope on 16 December 1980. The second phase was formally completed on the 31 December 1981, and had cost £3,142,210.

text: ASCA carried four large-area X-ray telescopes. At the focus of two of the telescopes is a gas imaging spectrometer (GIS), while a solid-state imaging spectrometer (SIS) is at the focus of the other two. The GIS is a gas-imaging scintillation proportional counter and is based on the GSPC that flew on the second Japanese X-ray astronomy mission TENMA. The two identical charge-coupled device (CCD) cameras were provided for the two SISs by a hardware team from MIT, Osaka University and ISAS.

text: The ARIESXXI radio telescope is an alt-azimuthal design with a rotating head above an azimuthal bearing or turning head.  It has full 360-degree movement in azimuth and horizon to horizon coverage in elevation (180 degrees total or slightly less?). As previously mentioned the telescope is Nasmyth-Cassegrain model that consists of a parabolic primary reflector and a hyperbolic secondary reflector that brings the dual system to a focus some 11 metres below, within the structure of the telescope housing, via a beam-guide. The optical configuration of the tertiary Nasmyth system is such that the focus is always maintained in the same place as the flat Nasmyth mirrors track the movement of the principle axis of the dual reflector to ensure a constant illumination of the receivers. This allows the receiver antennas to remain fixed in position and greatly simplifies the opto-mechanical design of the receiver suite.

text: In the following years, the telescope was used to track a variety of space probes. Between 11 March and 12 June 1960, it tracked the Pioneer 5 probe. The telescope was also used to send commands to the probe, including the one to separate the probe from its carrier rocket and the ones to turn on the more powerful transmitter when the probe was eight million miles away. It also received data from the probe, being the only telescope in the world capable of doing so at the time. In February 1966, Jodrell Bank was asked by the Soviet Union to track the USSR unmanned moon lander Luna 9 and recorded on its facsimile transmission of photographs from the moon's surface. The photos were sent to the British press and published before the Soviets themselves had made the photos public.

The telescope was also used to send commands to the probe, including the one to separate the probe from its carrier rocket and the ones to turn on the more powerful transmitter when the probe was eight million miles away. It also received data from the probe, being the only telescope in the world capable of doing so at the time. In February 1966, Jodrell Bank was asked by the Soviet Union to track the

text: For many years, the Moon has been recognized as an excellent site for telescopes. It is relatively nearby; astronomical seeing is not a concern; certain craters near the poles are permanently dark and cold, and thus especially useful for infrared telescopes; and radio telescopes on the far side would be shielded from the radio chatter of Earth. The lunar soil, although it poses a problem for any moving parts of telescopes, can be mixed with carbon nanotubes and epoxies and employed in the construction of mirrors up to 50 meters in diameter. A lunar zenith telescope can be made cheaply with ionic liquid.

answers: infrared telescopes;

text: The sizes of both moons are calculated with the assumption that they have the same infrared albedo as Haumea, which is reasonable as their spectra show them to have the same surface composition. Haumea's albedo has been measured by the Spitzer Space Telescope: from ground-based telescopes, the moons are too small and close to Haumea to be seen independently. Based on this common albedo, the inner moon, Namaka, which is a tenth the mass of Hiʻiaka, would be about 170 km in diameter.

text: The Submillimeter Array (SMA) consists of eight  diameter radio telescopes arranged as an interferometer for submillimeter wavelength observations. It is the first purpose-built submillimeter interferometer, constructed after successful interferometry experiments using the pre-existing  James Clerk Maxwell Telescope and  Caltech Submillimeter Observatory as an interferometer. All three of these observatories are located at Mauna Kea Observatory on Mauna Kea, Hawaii, and can be operated together as a ten element interferometer in the 230 and 345 GHz bands (eSMA, for extended Submillimeter Array). The baseline lengths presently in use range from , and up to  for eSMA operations. The radio frequencies accessible to this telescope range from 180 to 700 GHz which includes rotational transitions of dozens of molecular species as well as continuum emission from interstellar dust grains. Although the array is capable of operating both day and night, most of the observations take place at nighttime when the atmospheric phase stability is best.

text: Some psychologists suggest telescoping errors are due to the heuristics used to answer dating and frequency questions. When asked questions about frequency, people often answer using phrases like "all the time" and "everyday" and therefore don't account for exceptions. Depending on the events in question, this could lead to an over or under estimation of the occurrence of an event, and be perceived as telescoping. This over reporting is a result of telescoping because telescoping causes participants include events beyond the period. Therefore, heuristics may be responsible for some of the telescoping errors.

text: The main result of loop quantum gravity is the derivation of a granular structure of space at the Planck length.  This is derived from following considerations: In the case of electromagnetism, the quantum operator representing the energy of each frequency of the field has a discrete spectrum. Thus the energy of each frequency is quantized, and the quanta are the photons. In the case of gravity, the operators representing the area and the volume of each surface or space region likewise have discrete spectrum. Thus area and volume of any portion of space are also quantized, where the quanta are elementary quanta of space.  It follows, then, that spacetime has an elementary quantum granular structure at the Planck scale, which cuts off the ultraviolet infinities of quantum field theory.

text: Comets can be gone but not considered lost, even though they may not be expected back for hundreds or even thousands of years. With more powerful telescopes it has become possible to observe comets for longer periods of time after perihelion. For example, Comet Hale–Bopp was observable with the naked eye about 18 months after its approach in 1997. It is expected to remain observable with large telescopes until perhaps 2020, by which time it will be nearing 30th magnitude.

text: 1865: James Clerk Maxwell publishes his landmark paper A Dynamical Theory of the Electromagnetic Field, in which Maxwell's equations demonstrated that electric and magnetic forces are two complementary aspects ofelectromagnetism. He shows that the associated complementary electric and magnetic fields of electromagnetism travel through space, in the form of waves, at a constant velocity of 3.0 × 10 m/s. He also proposes that light is a form of electromagnetic radiation and that waves of oscillating electric and magnetic fields travel through empty space at a speed that could be predicted from simple electrical experiments. Using available data, he obtains a velocity of 310,740,000 m/s and states "This velocity is so nearly that of light, that it seems we have strong reason to conclude that light itself (including radiant heat, and other radiations if any) is an electromagnetic disturbance in the form of waves propagated through the electromagnetic field according to electromagnetic laws."

text: Phasor approach refers to a method which is used for vectorial representation of  sinusoidal waves like alternative currents and voltages or electromagnetic waves. The amplitude and the phase of the waveform is transformed into a vector where the phase is translated to the angle between the phasor vector and X axis and the amplitude is translated to vector length or magnitude.In this concept the representation and the analysis becomes very simple and the addition of two wave forms is realized by their vectorial summation.

text: Meniscus correctors are used as full aperture correctors, most commonly in a Maksutov telescope sub type called the Gregory or “spot” Maksutov–Cassegrain telescope. They are also used in the Bouwers meniscus telescope. There are Maksutov variations that use the same principle but place the meniscus lens as a sub-aperture corrector near the focus of the objective. There are other sub-aperture meniscus corrector catadioptric telescopes such as the Argunov–Cassegrain telescope and the Klevtsov–Cassegrain telescope.

text: Telescopic Handlers are like forklift trucks that have a telescoping extendable boom like a crane. Early telescopic handlers only lifted in one direction and did not rotate, however, several of the manufacturers have designed telescopic handlers that rotate 360 degrees through a turntable and these machines look almost identical to the Rough Terrain Crane. These new 360 degree telescopic handler/crane models have outriggers or stabiliser legs that must be lowered before lifting, however their design has been simplified so that they can be more quickly deployed. These machines are often used to handle pallets of bricks and install frame trusses on many new building sites and they have eroded much of the work for small telescopic truck cranes. Many of the worlds Armed forces have purchased telescopic handlers and some of these are the much more expensive fully rotating types. Their off road capability and their on site versatility to unload pallets using forks, or lift like a crane makes them a valuable piece of machinery.

text: Classical waves transfer energy without transporting matter through the medium (material). For example, waves in a pond do not carry the water molecules from place to place; rather the wave's energy travels through the water, leaving the water molecules in place. Additionally, charged particles, such as electrons and protons create electromagnetic fields when they move, and these fields transport the type of energy known as electromagnetic radiation, or light. A changing magnetic field will induce a changing electric field and vice versa—the two are linked. These changing fields form electromagnetic waves. Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.

text: The Pushchino Radio Astronomy Observatory has four notable radio telescopes (RT 22), each with mirrors at 22 meters. Constructed in 1959 these are fully steerable, and are designed to operate in millimeter and centimeter range of wavelength. Added to the equipage is the DKR 1000, a  wide-band  radio telescope instrument, on-line in 1964, operating  in the meter wavelength range. The DKR 1000 has arms that are 40 by 1000 meters. In 1973, another telescope was added to this set. The nomenclature is Large Phased Array with the designation BSA/LPI, operating in the meter wavelength range. The DKR 1000 and BSA/LPI, are currently the largest radio telescopes in the world, which operate in the meter range.

Of similar magnitude, Uranus and Vesta had most probably been seen but could not be recognized as planets because they appear so faint even at maximum brightness that their motion could not be detected. Uranus, when discovered in 1781, was the first planet discovered using technology (a telescope) rather than being spotted by the naked eye.

text: Electromagnetic spectrum refers to the full range of all frequencies of electromagnetic radiation and also to the characteristic distribution of electromagnetic radiation emitted or absorbed by that particular object. Devices used to measure an electromagnetic spectrum are called spectrograph or spectrometer. The visible spectrum is the part of the electromagnetic spectrum that can be seen by the human eye. The wavelength of visible light ranges from 390 to 700 nm. The absorption spectrum of a chemical element or chemical compound is the spectrum of frequencies or wavelengths of incident radiation. The emission spectrum refers to the spectrum of radiation emitted due to an atom or molecule making a transition from a higher to a lower energy state.

text: The Company was originally founded in Dublin by Thomas Grubb as the Grubb Telescope Company in 1833. Thomas Grubb was joined in 1864 by his son Howard who built on the company's reputation for quality optical instruments. Grubb was also known for building accurate electrically driven clock drives for equatorial mounted telescopes. Some of the telescopes produced in the 19th century include the "Great Melbourne Telescope" - a 48-inch-diameter (1.2 m) reflecting telescope with speculum primary mirror, the 27-inch refractor for the Vienna Observatory (1878), the 10-inch refractor at Armagh Observatory (1882), the 28-inch refractor at the Royal Observatory, Greenwich - the UK's largest refractor (1893), and the 10-inch refractor at Coats Observatory, Paisley (1898). In 1887 Grubb's firm built seven normal astrographs for the Carte du Ciel international photographic star catalogue project, 13 inch refracting telescopes all designed to produce uniform photographic plates.

text: Bernard Lovell built the Transit Telescope at Jodrell Bank in the late 1940s. This was a -diameter radio telescope that could only point directly upwards; the next logical step was to build a telescope that could look at all parts of the sky so that more sources could be observed, as well as for longer integration times. Although the Transit Telescope had been designed and constructed by the astronomers that used it, a fully steerable telescope would need to be professionally designed and constructed; the first challenge was to find an engineer willing to do the job. This turned out to be Charles Husband, whom Lovell first met on 8 September 1949.

text: There is some evidence against the boundary model. A study by Lee and Brown in 2004 looked at how four different groups dated news events under different conditions. They found that the different boundaries had no effect on date estimation, and the existence of a boundary had no effect on date estimation. This study suggests that telescoping is not due solely to boundaries.

text: A green rim is present at every sunset but it is too thin to be seen with the naked eye. Often a green rim changes to a green flash and back again during the same sunset. The best time to observe a green rim is about 10 minutes before sunset. That is too early to use any magnification like binoculars or a telescope to look directly at the Sun without potential harm to the eyes. (Of course, a magnified image might be projected onto a sheet of paper for safe viewing.) As the sun gets closer to the horizon, the green rim becomes fainter due to atmospheric reddening. According to the above, it is probably correct to conclude that although a green rim is present during every sunset, a green flash is rarer because of the required mirage.

text: Light consists of electromagnetic radiation of different wavelengths. Therefore, when the elements or their compounds are heated either on a flame or by an electric arc they emit energy in the form of light. Analysis of this light, with the help of a spectroscope gives us a discontinuous spectrum. A spectroscope or a spectrometer is an instrument which is used for separating the components of light, which have different wavelengths. The spectrum appears in a series of lines called the line spectrum. This line spectrum is called an atomic spectrum when it originates from an atom in elemental form. Each element has a different atomic spectrum. The production of line spectra by the atoms of an element indicate that an atom can radiate only a certain amount of energy. This leads to the conclusion that bound electrons cannot have just any amount of energy but only a certain amount of energy.

text: The primary payload, the Gamma Ray Observatory (GRO), was deployed on flight day 3. GRO's high-gain antenna failed to deploy on command; it was finally freed and manually deployed by Ross and Apt during an unscheduled contingency space walk, the first since April 1985. The following day, the two astronauts performed the first scheduled space walk since November 1985 to test means for astronauts to move themselves and equipment about while maintaining the then-planned Space Station Freedom. GRO science instruments were Burst and Transient Source Experiment (BATSE), Imaging Compton Telescope (COMPTEL), Energetic Gamma Ray Experiment Telescope (EGRET) and Oriented Scintillation Spectrometer Experiment (OSSE). GRO was the second of NASA's four Great Observatories. The Hubble Space Telescope, deployed during Mission STS-31 in April 1990, was the first. GRO was launched on a two-year mission to search for the high-energy celestial gamma ray emissions, which cannot penetrate Earth's atmosphere. At about 35,000 pounds, GRO was the heaviest satellite to be deployed into low-Earth orbit from the Shuttle. It was also designed to be the first satellite that could be refueled in orbit by Shuttle crews. Five months after deployment, NASA renamed the satellite the Arthur Holly Compton Gamma Ray Observatory, or Compton Observatory, after the Nobel Prize-winning physicist who did important work in gamma ray astronomy.

text: HIP 79431 b is located in orbit around a star whose metallicity had been challenging to be assessed due to the uncertainties within the molecular data line however it has not been typical for M Dwarfs to have strong emissions from the core data lines. This led to the inclusion of the HIP 79431 star to the KECK program in April 2009 as part of the exoplanet studies for low mass stars. During this study, 13 Doppler measurements of the star were done over a 6-month period using the High Resolution Echelle Spectrometer (HIRES). The exposure times used in its observation was 600 seconds which yielded a signal-to-noise ratio of just under 100. Each program observation required the use of iodine absorption lines in order to model the wavelength scale as well as the instrumental profile of the telescope and spectrometer optics. The Doppler experiments derived radial velocities fit the Keplerian model showing an unambiguous signal and orbital parameters which best fit planetary gravitational pull, this revealed the presence of the planet HIP 79431 b. However, there is no evidence that any additional planets was found.

text: Far infrared observations including submillimeter astronomy have revealed a number of sources at cosmological distances. With the exception of a few atmospheric windows, most of infrared light is blocked by the atmosphere, the observations generally take place from balloon or space-based instruments. Current observational experiments in the infrared include NICMOS, the Cosmic Origins Spectrograph, the Spitzer Space Telescope, the Keck Interferometer, the Stratospheric Observatory For Infrared Astronomy, and the Herschel Space Observatory. The next large space telescope planned by NASA, the James Webb Space Telescope will also explore in the infrared.

text: Aderin-Pocock has worked on many projects, from private industry to government contracts to academic research. She began in the Ministry of Defence and the Defence Evaluation and Research Agency on missile warning systems. She then worked on hand-held instruments to detect landmines. Aderin-Pocock moved back to Imperial College London in 1999 with a fellowship from the Science and Technology Facilities Council to work with the group developing a high-resolution spectrograph for the Gemini telescope in Chile, which probes the heart of stars by converting the starlight gathered by huge telescopes into the spectrum of colours, and then analyses them to work out what's happening billions of miles away.

text: The same academy of Cimento in Florence was involved in another disputation to compare Divini’s and Campani’s instruments in 1664. First tests were not favourable to either of them, notwithstanding the paragoni had been carefully arranged by Matteo and Giuseppe Campani brothers to put Divini at as much of a disadvantage as possible. In the paragone of April, 30th 1664 Divini used a telescope manufactured by him with a very complex optical system and previously sold to the nephew of Pope Alexander VII, Cardinal Flavio Chigi, for a very high price. Since Divini's instruments was in the possession of Cardinal Chigi, the Campani brothers were able to make all the arrangements and substitutions without notifying Divini beforehand. Then Divini arrived in the test place to find his telescope arranged on chairs and was not allowed to check the conditions of the lenses or to make any changes on it,  while Campani's telescope was beautifully mounted. Divini's telescope gave a worse performance of Campani's, but Divini, rather than making excuses, admitted that Campani's instrument was better than his and begged to be allowed to make the Cardinal a better telescope to replace the manifestly defective one. This easy victory and the humiliation of Divini initiated Campani to the success. The academy of Cimento and Prince Leopold was eager to know if Campani's telescopes were, indeed, better than those of Divini that had served them so well in Florence. So they inquired that the previous paragone in Rome was unfair and commanded specially designed experiments based on the reading of texts at a distance. The first of these does not permitted to establish the winner because the competitors used different telescopes; as Campani refuted to do the experiment in Florence, the test was done in different places and times (autumn 1964), Campani moved a lamp closer to the sheet to be read, whose letters could be recognized also by insight as being made of known words and famous phrases. The Accademia of Cimento devised better criteria, more similar to nowadays ophthalmic characters tables, but in the subsequent paragoni, in the late 1664, no one's telescope was definitely declared as best performer. In 1665 the Grand Duke Ferdinand II and Prince Leopold acquired a number of Campani and new Divini telescopes and subjected them to tests of their own in astronomical observations. Sometimes no clear advantage accrued either to Campani or Divini, until in July a 50-palm Campani telescope made for Cardinal Borromeo resulted to be much better than all other telescopes of similar length. Divini did not take Campani's victory well, arguing a freak or bare luck. Both the antagonists proposed to the Accademia del Cimento an impartial test based on the manufacturing of the best objective lenses with given curvature starting from the same piece of glass  divided in two parts. In this way their skills as lens-makers could have been assessed, but Prince Leopold did not act on the proposal: the dispute was over and Campani was the undisputed winner. Despite the undeniable merits of Divini's telescopes, it was just one of Campani's telescopes that won the day. Rather than this single defeat, they were mainly Cassini’s discoveries that promoted the products by Campani, up to the end of the century. Divini, resigned to leave the top position of his art to the antagonist, wrote with pride in 1666: "my glasses have lost nothing in these paragoni, in fact after the contest and even today I have new orders from Florence" (from letter to C. A. Manzini). There are also witnesses that as late as in 1671 lenses were commissioned to both Campani and Divini from the great Observatoire de Paris, directed by Cassini.

text: An electromagnetic wave consists of two waves that are oscillations of the electric and magnetic fields. An electromagnetic wave travels in a direction that is at right angles to the oscillation direction of both fields. In the 19th century, James Clerk Maxwell showed that, in vacuum, the electric and magnetic fields satisfy the wave equation both with speed equal to that of the speed of light. From this emerged the idea that light is an electromagnetic wave. Electromagnetic waves can have different frequencies (and thus wavelengths), giving rise to various types of radiation such as radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and Gamma rays.

text: At nearly  distant, Kepler-186f is too far and its star too faint for current telescopes or the next generation of planned telescopes to determine its mass or whether it has an atmosphere. However, the discovery of Kepler-186f demonstrates conclusively that there are other Earth-sized planets in habitable zones. The Kepler spacecraft focused on a single small region of the sky but next-generation planet-hunting space telescopes, such as TESS and CHEOPS, will examine nearby stars throughout the sky. Nearby stars with planets can then be studied by the upcoming James Webb Space Telescope and future large ground-based telescopes to analyze atmospheres, determine masses and infer compositions. Additionally the Square Kilometer Array would significantly improve radio observations over the Arecibo Observatory and Green Bank Telescope.

text: Based only on uncertain descriptions of the first practical telescope, invented by Hans Lippershey in the Netherlands in 1608, Galileo, in the following year, made a telescope with about 3x magnification. He later made improved versions with up to about 30x magnification. With a Galilean telescope the observer could see magnified, upright images on the earth—it was what is commonly known as a terrestrial telescope or a spyglass. He could also use it to observe the sky; for a time he was one of those who could construct telescopes good enough for that purpose. On 25 August 1609, he demonstrated one of his early telescopes, with a magnification of about 8 or 9, to Venetian lawmakers. His telescopes were also a profitable sideline for Galileo selling them to merchants who found them useful both at sea and as items of trade. He published his initial telescopic astronomical observations in March 1610 in a brief treatise entitled Sidereus Nuncius (Starry Messenger).

text: Before the advent of modern mass-produced telescopes the price of even a modest instrument was often beyond the means of an aspiring amateur astronomer. Building your own was the only economical method to obtain a suitable telescope for observing. There were many published works that helped spark an interest in building telescopes such as Irish telescope maker Rev. W. F. A. Ellison's 1920 book "The Amateur's Telescope".

text: Automated Patrol Telescope (APT) is operated by the University of NSW (UNSW) is a wide-field CCD imaging telescope. The 0.5m telescope has a 5 degree field of view and can be operated remotely or in a fully automatic mode. The telescope has an optical design that more resembles that of a Schmidt camera, but has a 3-element lens to achieve a wide, corrected field of view. The APT was developed by extensively modifying the optical, mechanical and electronic systems of a Baker-Nunn satellite tracking instrument. The Baker-Nunn telescope had been located at Woomera in South Australia during the 1960's, and afterward was stationed at Orroral Valley near Canberra. The camera was donated by the Smithsonian Institution to UNSW in 1982.

text: In late 1668 Isaac Newton built his first reflecting telescope. He chose an alloy (speculum metal) of tin and copper as the most suitable material for his objective  mirror. He later devised means for shaping and grinding the mirror and may have been the first to use a pitch lap to polish the optical surface. He chose a spherical shape for his mirror instead of a parabola to simplify construction; even though it would introduce spherical aberration, it would still correct chromatic aberration. He added to his reflector what is the hallmark of the design of a Newtonian telescope, a secondary diagonally mounted mirror near the primary mirror's focus to reflect the image at a 90° angle to an eyepiece mounted on the side of the telescope. This unique addition allowed the image to be viewed with minimal obstruction of the objective mirror. He also made the tube, mount, and fittings. Newton's first version had a primary mirror diameter of  and a focal ratio of f/5. He found that the telescope worked without colour distortion and that he could see the four Galilean moons of Jupiter and the crescent phase of the planet Venus with it. Newton's friend Isaac Barrow showed a second telescope to a small group from the Royal Society of London at the end of 1671. They were so impressed with it that they demonstrated it to Charles II in January 1672. Newton was admitted as a fellow of the society in the same year.

text: The idea that curved mirrors behave like lenses dates back at least to Alhazen's 11th century treatise on optics, works that had been widely disseminated in Latin translations in early modern Europe.  Soon after the invention of the refracting telescope, Galileo, Giovanni Francesco Sagredo, and others, spurred on by their knowledge of the principles of curved mirrors, discussed the idea of building a telescope using a mirror as the image forming objective. There were reports that the Bolognese Cesare Caravaggi had constructed one around 1626 and the Italian professor Niccolò Zucchi, in a later work, wrote that he had experimented with a concave bronze mirror in 1616, but said it did not produce a satisfactory image. The potential advantages of using parabolic mirrors, primarily reduction of spherical aberration with no chromatic aberration, led to many proposed designs for reflecting telescopes. The most notable being James Gregory, who published an innovative design for a ‘reflecting’ telescope in 1663. It would be ten years (1673), before the experimental scientist Robert Hooke was able to build this type of telescope, which became known Gregorian telescope.

text: There is a zone of the atmosphere in which ozone absorbs some 98% of non-ionizing but dangerous UV-C and UV-B. This so-called ozone layer, starts at about  and extends upward. Some of the ultraviolet spectrum that does reach the ground (the part that begins above energies of 3.1 eV, a wavelength less than 400 nm) is non-ionizing, but is still biologically hazardous due to the ability of single photons of this energy to cause electronic excitation in biological molecules, and thus damage them by means of unwanted reactions. An example is the formation of pyrimidine dimers in DNA, which begins at wavelengths below 365 nm (3.4 eV), which is well below ionization energy. This property gives the ultraviolet spectrum some of the dangers of ionizing radiation in biological systems without actual ionization occurring. In contrast, visible light and longer-wavelength electromagnetic radiation, such as infrared, microwaves, and radio waves, consists of photons with too little energy to cause damaging molecular excitation, and thus this radiation is far less hazardous per unit of energy.

text: Faraday's and Ampère's work showed that a time-varying magnetic field acted as a source of an electric field, and a time-varying electric field was a source of a magnetic field. Thus, when either field is changing in time, then a field of the other is necessarily induced. Such a phenomenon has the properties of a wave, and is naturally referred to as an electromagnetic wave. Electromagnetic waves were analysed theoretically by James Clerk Maxwell in 1864. Maxwell developed a set of equations that could unambiguously describe the interrelationship between electric field, magnetic field, electric charge, and electric current. He could moreover prove that such a wave would necessarily travel at the speed of light, and thus light itself was a form of electromagnetic radiation. Maxwell's Laws, which unify light, fields, and charge are one of the great milestones of theoretical physics.

text: Due to problems with the mirrors and because the telescope was unwieldy, the telescope did not prove to be a substantial improvement over smaller telescopes. The weather was rarely suitable for the telescope, and most objects observed by Herschel were also visible in his smaller telescopes. The final observation made by the telescope was in 1815.

text: The spacing of the molybdenum and silicon layers on each telescope's mirror is the primary determinant of the telescope's photon energy response function. The ALEXIS multilayer mirrors also employ a "wavetrap" feature to significantly reduce the mirror's reflectance for He II 304 Angstrom geocoronal radiation which can be a significant background source for space borne EUV telescopes. These mirrors, produced by Ovonyx, Inc., are highly curved yet have been shown to have very uniform multilayer coatings and hence have very uniform EUV reflecting properties over their entire surfaces. The efforts in designing, producing and calibrating the ALEXIS telescope mirrors have been previously described in Smith et al., 1990.

text: The waterhole, or water hole, is an especially quiet band of the electromagnetic spectrum between 1,420 and 1,666 megahertz, corresponding to wavelengths of 21 and 18 centimeters respectively.  It is a popular observing frequency used by radio telescopes in radio astronomy.   The term was coined by Bernard Oliver in 1971. The strongest hydroxyl radical spectral line radiates at 18 centimeters, and hydrogen at 21 centimeters. These two molecules, which combined form water, are widespread in interstellar gas, and their presence radiates radio noise at these frequencies.  Therefore, the spectrum between these frequencies form a "quiet" channel in the interstellar radio noise background.  Bernard M. Oliver theorized that the waterhole would be an obvious band for communication with extraterrestrial intelligence, hence the name, which is a form of pun: in English, a watering hole is a vernacular reference to a common place to meet and talk. Several programs involved in the search for extraterrestrial intelligence, including SETI@home, search in the waterhole radio frequencies.

text: The majority of IRTF users prefer to use IRTF remotely.  Observers can use IRTF from any location with a high speed internet connection, such as their office or home, anywhere around the world.  The observer controls the instrument via a VNC session, just as they would at the summit, and communicates with the telescope operator via phone, Polycom, or Skype.  The observer calls in and logs in for their time allocation.  Remote observing has several advantages.  Remote observing spares the observer the time and cost of traveling from their home institution to Hawaii.  In the past, when observers traveled to the telescope, the telescope was scheduled in full nights.  With remote observing, observers only need to submit a request for the amount of time they need, when they need it, instead of asking for whole nights.  Since the observers do not travel to Hawaii, they can also request to use the telescope more frequently.  This has enabled the IRTF to support many programs where frequent observations of targets are necessary, such as weekly monitoring of solar system objects.  Remote observing has also allowed the IRTF to support target-of-opportunity (ToO) programs.  These are programs of high scientific merit where the timing of the observation cannot be predicted at the time that telescope is scheduled.  Examples include supernovae, which explode unexpectedly, or near-earth asteroids that may be discovered shortly before their closest approach to the Earth.  Although the observers are usually remote, the telescope operator is at the summit to ensure the safety of the facility, assist the observer, and troubleshoot problems that may arise during the night.

text: In contrast to a true-color image, a false-color image sacrifices natural color rendition in order to ease the detection of features that are not readily discernible otherwise – for example the use of near infrared for the detection of vegetation in satellite images. While a false-color image can be created using solely the visual spectrum (e.g. to accentuate color differences), typically some or all data used is from electromagnetic radiation (EM) outside the visual spectrum (e.g. infrared, ultraviolet or X-ray). The choice of spectral bands is governed by the physical properties of the object under investigation.

In this case it took 150 days. Two telescopes are used to detect the planet and the time difference between identification by each telescope is used to calculate the distance to the planet. This also contributes to determining the mass of the planet which is about half of Jupiter's. The planet orbits a star with a mass of 0.7 solar masses and is 3.1 AU

Other types of electromagnetic radiation, with frequencies above the RF range, are infrared, visible light, ultraviolet, X-rays and gamma rays. Since the energy of an individual photon of radio frequency is too low to remove an electron from an atom, radio waves are classified as non-ionizing radiation.

text: The terahertz gap is an engineering term for a band of frequencies in the terahertz region of the electromagnetic spectrum between radio waves and infrared light for which practical technologies for generating and detecting the radiation do not exist. It is defined as 0.1 to 10 THz (wavelengths of 3 mm to 30 µm). Currently, at frequencies within this range, useful power generation and receiver technologies are inefficient and impractical. Mass production of devices in this range and operation at room temperature (at which kT is equal to the energy of a photon with a frequency of 6.2 THz) are mostly unfeasible. Hence, a gap exists between mature microwave technologies in the highest frequencies of the radio spectrum and the well developed optical engineering of infrared detector

text: To find an object, such as globular cluster NGC 6712, one does not need to look up the RA and Dec coordinates in a book, and then move the telescope to those numerical readings.  Rather, the object is chosen from the database and arrow markers appear in the display which indicate the direction to move the telescope.  The telescope is moved until the distance value reaches zero. When both the RA and Dec axes are thus "zeroed out", the object should be in the eyepiece. The user therefore does not have to go back and forth from some other database (such as a book or laptop) to match the desired object's listed coordinates to the coordinates on the telescope. However, many DSCs, and also go-to systems, can work in conjunction with laptop sky programs.

text: Ten Bruggencate became chief astronomer at the Potsdam Observatory in 1935. The most valuable equipment at that time at Potsdam was the solar telescope in the Einstein Tower. From that time on, the main focus of ten Bruggencate's research became the Sun. In 1941, during World War II, ten Bruggencate became the director at the Göttingen University Observatory. In pursuing his interest in observing the Sun, he looked for a new solar telescope. The already existing observatory at the Hainberg, south east of Göttingen, provided the best location within the surrounding area. The interest of the military in the effect of the Sun on short wave radio communication made it possible to build this observatory during the war. Military patronage and ten Bruggencate's profound knowledge of the solar telescope in Potsdam assisted construction of the new telescope.

text: Modern Radio interferometers consist of widely separated radio telescopes observing the same object that are connected together using coaxial cable, waveguide, optical fiber, or other type of transmission line. This not only increases the total signal collected, it can also be used in a process called Aperture synthesis to vastly increase resolution. This technique works by superposing ("interfering") the signal waves from the different telescopes on the principle that waves that coincide with the same phase will add to each other while two waves that have opposite phases will cancel each other out. This creates a combined telescope that is the size of the antennas furthest apart in the array. In order to produce a high quality image, a large number of different separations between different telescopes are required (the projected separation between any two telescopes as seen from the radio source is called a "baseline") - as many different baselines as possible are required in order to get a good quality image. For example, the Very Large Array has 27 telescopes giving 351 independent baselines at once.

text: Surface-wave-sustained plasmas (SWP) can be operated in a large variety of recipient geometries.  The pressure range accessible for surface-wave-excited plasmas depends on the process gas and the diameter of the recipient.  The larger the chamber diameter, the lower the minimal pressure necessary for the SWP mode. Analogously, the maximal pressure where a stable SWP can be operated decreases with increasing diameter.  The numerical modelling of SWPs is quite involved. The plasma is created by the electromagnetic wave, but it also reflects and guides this same wave. Therefore, a truly self-consistent description is necessary.

text: SN 2002cx was discovered on 2002 May 12.21 UT by W. M. Wood-Vasey, G. Aldering, and P. Nugent of LBL with the Oschin 1.2-m telescope at Palomar.  On 2002 May 17.2 a spectrum taken by T. Matheson, S. Jha, P. Challis, and R. Kirshner of the CfA with the 1.5-m telescope at FLWO suggested it was a peculiar SN 1991T like type Ia. SN 2002cx had photometric follow up taken at Lick using KAIT and the Nickel telescope, and further spectra were taken at FLWO and Keck.

text: The light from the stars was captured with optical fibres, precisely positioned by a robot. The robot picks up optical fibres, one by one, and places them on a metal plate in the telescope. Each fibre is in the right place to catch the light from a single star. By using many fibres, more than 100 stars can be studied at the same time. Travelling down the tiny glass threads, the starlight enters an instrument that spreads it out into its component wavelengths or 'colours', the way a prism does. These colours tell astronomers about the chemical elements a star contains and how it is moving. From that, the astronomers can work out how old the stars are, where they came from, and how they are related. And that's the key that unlocks the history of our Galaxy.

text: With the exception of the Bolshoi Teleskop Azimutalnyi (BTA-6) and William Herschel's 40-foot telescope, major optical telescopes prior to the MMT used equatorial mounts. The MMT heralded a change in telescope design; all major optical telescopes since the MMT have been built with alt-azimuth mounts. Several technologies pioneered at the MMT contributed to the success of the subsequent generation of large telescopes. These included: high dynamic-range servos for the alt-azimuth mount; highly accurate pointing that eliminated the need for sky charts; co-alignment and co-phasing of multiple telescopes; improvements to optical performance by attention to thethermal environment of the facility; contributions to vacuum coatings deposition, optics cleaning, and maintenance; and early experiments in co-phased adaptive optics.

text: The first optical instruments were telescopes used for magnification of distant images, and microscopes used for magnifying very tiny images. Since the days of Galileo and Van Leeuwenhoek, these instruments have been greatly improved and extended into other portions of the electromagnetic spectrum. The binocular device is a generally compact instrument for both eyes designed for mobile use. A camera could be considered a type of optical instrument, with the pinhole camera and camera obscura being very simple examples of such devices.

text: The absence of air makes outer space an ideal location for astronomy at all wavelengths of the electromagnetic spectrum. This is evidenced by the spectacular pictures sent back by the Hubble Space Telescope, allowing light from more than 13 billion years ago—almost to the time of the Big Bang—to be observed. However, not every location in space is ideal for a telescope. The interplanetary zodiacal dust emits a diffuse near-infrared radiation that can mask the emission of faint sources such as extrasolar planets. Moving an infrared telescope out past the dust will increase the effectiveness of the instrument. Likewise, a site like the Daedalus crater on the far side of the Moon could shield a radio telescope from the radio frequency interference that hampers Earth-based observations.

text: Through his career T. W. Webb served as a clergyman at various places including Gloucester, and finally in 1852 was assigned to the parish of Hardwicke near the border with Wales.  In addition to serving faithfully the members of his parish, T. W. Webb pursued astronomical observation in his spare time.  On the grounds of the vicarage or parsonage he built a small canvas and wood observatory that was home to instruments including a small 3.7" (94mm) refractor. Webb acquired progressively larger refractors and reflectors with which the observations in the guide were made. The largest telescope was a 9-1/3" (225mm) silver on glass reflector used from 1866 until his last observation in March 1885.  It was at Hardwick that he wrote his classic astronomical observing guide Celestial Objects for Common Telescopes (2 vols) in 1859 for which he is best known today.  This two volume work was written as a guide for the amateur astronomer, containing instructions on the use of a telescope as well as detailed descriptions of what could be observed with it. This work became the standard observing guide of amateur astronomers worldwide, and remained so until well into the 20th Century, gradually supplanted by more modern guides such as Burnham's Celestial Handbook.

text: For observation purposes, the optimal location for an optical telescope is undoubtedly in outer space. There the telescope can make observations without being affected by the atmosphere. However, at present it remains costly to lift telescopes into orbit. Thus the next best locations are certain mountain peaks that have a high number of cloudless days and generally possess good atmospheric conditions (with good seeing conditions). The peaks of the islands of Mauna Kea, Hawaii and La Palma possess these properties, as to a lesser extent do inland sites such as Llano de Chajnantor, Paranal, Cerro Tololo and La Silla in Chile. These observatory locations have attracted an assemblage of powerful telescopes, totalling many billion US dollars of investment.

text: For reflecting telescopes, which use a curved mirror in place of the objective lens, theory preceded practice. The theoretical basis for curved mirrors behaving similar to lenses was probably established by Alhazen, whose theories had been widely disseminated in Latin translations of his work. Soon after the invention of the refracting telescope Galileo, Giovanni Francesco Sagredo, and others, spurred on by their knowledge that curved mirrors had similar properties as lenses, discussed the idea of building a telescope using a mirror as the image forming objective. The potential advantages of using parabolic mirrors (primarily a reduction of spherical aberration with elimination of chromatic aberration) led to several proposed designs for reflecting telescopes, the most notable of which was published in 1663 by James Gregory and came to be called the Gregorian telescope, but no working models were built. Isaac Newton has been generally credited with constructing the first practical reflecting telescopes, the Newtonian telescope, in 1668 although due to their difficulty of construction and the poor performance of the speculum metal mirrors used it took over 100 years for reflectors to become popular. Many of the advances in reflecting telescopes included the perfection of parabolic mirror fabrication in the 18th century, silver coated glass mirrors in the 19th century, long-lasting aluminum coatings in the 20th century, segmented mirrors to allow larger diameters, and active optics to compensate for gravitational deformation. A mid-20th century innovation was catadioptric telescopes such as the Schmidt camera, which uses both a lens (corrector plate) and mirror as primary optical elements, mainly used for wide field imaging without spherical aberration.

text: The  refracting telescope on Mt. Hamilton was Earth's largest refracting telescope during the period from when it saw first light on January 3, 1888, until the construction of Yerkes Observatory in 1897. Warner & Swasey designed and built the telescope mounting, with the  lens manufactured by one of the Clark sons, Alvan Graham. E. E. Barnard used the telescope in 1892 to discover a fifth moon of Jupiter, Amalthea. This was the first addition to Jupiter's known moons since Galileo observed the planet through his parchment tube and spectacle lens. The telescope provided spectra for W. W. Campbell's work on the radial velocities of stars.

text: As a variation of standard web-based assessment methods, the SAPA methodology borrows by analogy a technique used in radio and optical astronomy: Synthetic Aperture Measurement. The resolution of a telescope is limited by its diameter which may be functionally increased a great deal by combining input from multiple, linked sites into one coherent image. Effectively, a very large telescope is created by synthesizing the input of many smaller ones. A classic example in radio astronomy is the Very Large Array, part of the National Radio Astronomy Observatory in Socorro, New Mexico, where 27 relatively small (≈ 25 meter) radio telescopes are spread out in a Y-shaped configuration to simulate the resolution of a 36 km telescope. The configuration is adjustable so that the telescope can either emphasize resolution (by maximizing the distance covered) or sensitivity (by concentrating the telescopes close to each other). In optical astronomy similar techniques are used in inferometry at the W. M. Keck Observatory in Hawaii with "outriggers" to supplement the main telescope. Similar techniques are available for "telemetric assessment" of psychological constructs. Rather than combining signals from the same source using different telescopes as is done in astronomy, the structure of personality can be studied by combining the responses of many people across more items than any one person is willing to take. This is not an entirely novel procedure.  The Educational Testing Service, for example, has long used the very large samples available when students take the SAT or GRE to develop new items by randomly giving small subsets of items to much smaller (but still quite large) subsamples of students. The SAPA methodology allows for these techniques to be used by a broader population of researchers by making use of open source and public domain software.

text: Sexton High School was not only an engineering marvel, it was a piece of architectural art. The school was designed at the very end of the Art Deco period. Had it been designed just a few years later, it probably would have been in the International Style. The geometric characteristics of the Art Deco style are quite prominent in Sexton's exterior.  When one first looks at the building, the eye is immediately drawn to the eight-story clock tower flanking the north end of the building. At the top, the corners have a stepped look, which is common among Art Deco buildings. As the tower grows in height, there are step backs, providing a telescope effect. Below the clock face, narrow glass block windows and chrome spandrels give an extra sense of height to the tower.

text: Classically, electromagnetic radiation consists of electromagnetic waves, which are synchronized oscillations of electric and magnetic fields that propagate at the speed of light through a vacuum.  The oscillations of the two fields are perpendicular to each other and perpendicular to the direction of energy and wave propagation, forming a transverse wave. Electromagnetic waves can be characterized by either the frequency or wavelength of their oscillations, which determines their position in the electromagnetic spectrum, which includes, in order of increasing frequency and decreasing wavelength: radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays.

text: The 1.3 m (51-inch) large-field R-C telescope was produced by DFM Engineering and then corrected and automated by NOFS staff. Corning Glass Works and Kodak made the primary mirror. The hyperbolic secondary has an advanced, computer-controlled collimation (alignment) system in order to permit very precise positions of stars and satellites (milliarcsecond astrometry) across its wide field of view. This system analyzes optical aberrations of the optical path, modeled by taking slope fits of the wavefront deviations revealed using a Hartmann mask. The telescope also now sports a state-of-the art, cryogenic wide-field mosaic CCD camera. It will also permit employment of the new "Microcam", an orthogonal transfer array (OTA), with Pan-STARRS heritage. Other advanced camera systems are also deployed for use on this telescope, such as the LANL-produced RULLI single photon counter, nCam. Using the telescope's special software controls, the telescope can track both stars and man-made satellites orbiting the Earth, while the camera images both. The 1.3 m dome itself is compact, owing to the fast overall optics at f/4. It is located near by and southwest of, the very large 61-inch dome. In addition to astrometric studies (such as for Space Situational Awareness, SDSS and SST), research on this telescope includes the study of blue and K-Giant stars, celestial mechanics and dynamics of multiple star systems, characterizations of artificial satellites, and the astrometry and transit photometry of exoplanets. Astrometrically, exoplanets also confuse centroid of a parent star's PSF—and there are many exoplanets—so the impact of their not-bland dynamics must be understood.

text: The Huygens contrived some ingenious arrangements for aiming these "aerial telescopes" at an object visible in the night sky. The telescope could be aimed at bright objects such as planets by looking for their image cast on a white pasteboard ring or oiled translucent paper screen and then centering them in the eyepiece. Fainter objects could be found by looking for the reflection of a lamp held in the observer's hand being bounced back by the objective and then centering that reflection on the object. Other contrivances for the same purpose are described by Philippe de la Hire and by Nicolaas Hartsoeker. The objectives for aerial telescopes sometimes had very long focal lengths. Christiaan Huygens states that in 1686 he and his brother made objectives of 8 inch (200 mm) and 8.5 inch (220 mm) diameter and 170 and 210 ft (52 and 64 m) focal length, respectively. Constantijn Huygens, Jr. presented a 7.5 inch (190 mm) diameter 123 ft (37.5 m) focal length objective to the Royal Society of London in 1690. Adrien Auzout and others made telescopes of from 300 to 600 ft (90 to 180 m) focal length, and Auzout proposed a huge aerial telescope 1,000 ft in length that he would use "to observe animals on the Moon".

text: Each of the individual telescopes have a 39 feet aperture, 350 mirrors on each dish, and a 3.5 degree field of view. The telescopes are built on a Davies-Cotton optical design, which uses a spherical reflector and is easy to construct and align. This design does cause a small time spread in the signal, but this spread is very small (~ 4 nanoseconds). The camera on each telescope has 499 individual photomultiplier tubes. VERITAS, like other IACTs, are most sensitive to the highest energy cosmic rays. Its full range of sensitivity is from 85 GeV to over 30 TeV (although the spectral reconstruction does not start until at least 100 GeV). The energy and angular resolution depend on the energy of the incident gamma ray but at 1 TeV the energy resolution is ~17%, and the angular resolution is 0.08 degrees. The entire array has an effective area of 100,000 square meters.

text: At nearly  distant, Kepler-438b is too remote and its star too far for current telescopes or the next generation of planned telescopes to determine its mass or whether it has an atmosphere. The Kepler spacecraft focused on a single small region of the sky but next-generation planet-hunting space telescopes, such as TESS and CHEOPS, will examine nearby stars throughout the sky. Nearby stars with planets can then be studied by the upcoming James Webb Space Telescope and future large ground-based telescopes to analyze atmospheres, determine masses and infer compositions. Additionally the Square Kilometer Array would significantly improve radio observations over the Arecibo Observatory and Green Bank Telescope.

text: Even before the end of the war, the Soviet government made a decision to restore the Observatory. In 1946, it began the construction after having cleared the territory. In May 1954, the Observatory was re-opened, not only having been restored but considerably expanded in terms of instruments, employees and research subjects. New departments had been created, such as the Department of Radio Astronomy and Department of Instrument Making (with its own optical and mechanical workshop). The surviving old instruments were repaired, modernized and put into service once again. Also installed were new instruments, such as the  refractor, a horizontal meridian device, a photographic polar telescope, a big zenith telescope, stellar interferometer, 2 solar telescopes, coronagraph, a big radio telescope and all kinds of labware.The 65 cm Zeiss refractor was originally intended as a gift from then Chancellor of Germany Adolf Hitler to the Italian Benito Mussolini, but it was not delivered and instead was taken by the Soviet Union.

text: A team at the University of California, Irvine, led by Asantha Cooray, was the first to detect and characterize HXMM01 in data from the Herschel space telescope's HerMES instrument. Initially noticed as an "amazing, bright blob" in an otherwise cold region of the cosmos, the galaxy was revealed to be an extremely bright submillimeter galaxy (SMG) after an extensive series of observations across the electromagnetic spectrum. Analyses of the data, published in May 2013, revealed the galaxy to be a merging pair with a mass at least ten times that of the Milky Way.

text: Like Gregory before him, Newton found it hard to construct an effective reflector. It was difficult to grind the speculum metal to a regular curvature. The surface also tarnished rapidly; the consequent low reflectivity of the mirror and also its small size meant that the view through the telescope was very dim compared to contemporary refractors. Because of these difficulties in construction, the Newtonian reflecting telescope was  initially not widely adopted. In 1721 John Hadley showed a much-improved model to the Royal Society. Hadley had solved many of the problems of making a parabolic mirror. His Newtonian with a mirror diameter of  compared favourably with the large aerial refracting telescopes of the day. The size of reflecting telescopes subsequently grew rapidly, with designs doubling in primary mirror diameter about every 50 years.

text: The OSO and OAO missions demonstrated the important role space-based observations could play in astronomy, and in 1968, NASA developed firm plans for a space-based reflecting telescope with a mirror 3 m in diameter, known provisionally as the Large Orbiting Telescope or Large Space Telescope (LST), with a launch slated for 1979. These plans emphasized the need for manned maintenance missions to the telescope to ensure such a costly program had a lengthy working life, and the concurrent development of plans for the reusable space shuttle indicated that the technology to allow this was soon to become available.

text: At the library clock tower, Greg (Ethan Embry) and Tamara (Sonequa Martin-Green) remove Hook's (Colin O'Donoghue) hood, begin their plot to take magic from Storybrooke, and look for Greg's father. The outsiders offer Hook a chance to help them, but Hook says that he already succeeded in his mission in killing Rumplestiltskin. But the two show Hook that his mission failed by giving him his telescope to show him that Mr. Gold and Lacey are still alive. Hook reluctantly gives in to their demands. At the same time, at the docks, David (Josh Dallas) and Mary Margaret discuss what to do about Regina, knowing that every time they tried to trust her she kept breaking those promises, unaware that Regina, posing as a fisherman, is hearing the conversation and vows that she will not be locked away. The following morning, Regina approaches Henry at the park and tries to manipulate him into believing that his family is about to take him away from her by showing off the magic beans that would transport them back to the Enchanted Forest. However, when Regina tells Henry that she plans to solve the problem by unleashing a fail-safe trigger that would wipe out Storybrooke, Henry tells Regina that she has not changed. Before he can warn the family, Regina takes out her book of spells and gives him a short-term memory block to make him forget about the conversation and they start over as if nothing happened.

text: When making observations, scientists look through telescopes, study images on electronic screens, record meter readings, and so on. Generally, on a basic level, they can agree on what they see, e.g., the thermometer shows 37.9 degrees C. But, if these scientists have different ideas about the theories that have been developed to explain these basic observations, they may disagree about what they are observing. For example, before Albert Einstein's general theory of relativity, observers would have likely interpreted the image at left as five different objects in space. In light of that theory, however, astronomers will tell you that is actually only two objects, one in the center and four different images of the same object around the sides. Alternatively, if other scientists suspect that something is wrong with the telescope and only one object is actually being observed, they are operating under yet another theory. Observations that cannot be separated from theoretical interpretation are said to be theory-laden.

text: The study of galaxies and our current understanding of the formation and evolution of the large and small scale structures are to a large extend based on the observations carried out by mid‐size telescopes. Even at the era of large and very large telescopes, such observations are still pursued thanks to advances in the instrumentation. While there are new frontiers to be explored by very large and extremely large telescopes, there are still enormous details which require further explorations. For economic and flexibility reasons there are still demands for 2‐4m class telescopes. These telescopes can complement others observing facilities to address some of the most fundamental questions related to galaxies such as the evolution of the cosmic web of galaxies, metal production and distribution within and between galaxies, formation of the present day Hubble sequence and also understanding our own galaxy.

text: Radio telescopes are directional radio antennas used for radio astronomy. The dishes are sometimes constructed of a conductive wire mesh whose openings are smaller than the wavelength being observed. Multi-element Radio telescopes are constructed from pairs or larger groups of these dishes to synthesize large 'virtual' apertures that are similar in size to the separation between the telescopes; this process is known as aperture synthesis. As of 2005, the current record array size is many times the width of the Earth—utilizing space-based Very Long Baseline Interferometry (VLBI) telescopes such as the Japanese HALCA (Highly Advanced Laboratory for Communications and Astronomy) VSOP (VLBI Space Observatory Program) satellite. Aperture synthesis is now also being applied to optical telescopes using optical interferometers (arrays of optical telescopes) and aperture masking interferometry at single reflecting telescopes. Radio telescopes are also used to collect microwave radiation, which is used to collect radiation when any visible light is obstructed or faint, such as from quasars. Some radio telescopes are used by programs such as SETI and the Arecibo Observatory to search for extraterrestrial life.

It detected the x-ray fluorescence (XRF) of crystal compounds created through the interaction of the electron shell with the solar wind particles to measure the abundance of the three main components: magnesium, silicon and aluminium. The detection of iron, calcium and titanium depended on the solar activity. The detection range for x-rays was 0.5 to 10 keV. The spectrometer and XSM (described below) together weighed 5.2 kg and had a power consumption of 18 watts.

text: Varying accounts are cited to support Janssen as a possible inventor of the telescope. German astronomer Simon Marius wrote an account to his patron Johan Philip Fuchs von Bimbach about meeting an unnamed Dutchman at the 1608 Autumn Frankfurt Fair (which ran the month of September) who tried to sell him a device that sounded like a telescope. Given his history as a street seller, there is speculation this unnamed Dutchman could have been Zacharias Janssen, which would mean Janssen had a telescope at least a month before Lippershey's October 2, 1608 patent date. William de Boreel, who visited Middelburg to research the invention in 1655, interviewed Janssen's son Johannes. Boreel concluded that Janssen's telescope was finished about 1610. His research was referenced by Pierre Borel in De vero telescopii inventore. There are other claims that Janssen constructed the first telescope in 1604, or even earlier. Janssen's son Johannes testified under oath that Hans Lippershey had stolen his father's invention of the telescope, and that his father had invented the device in 1590.

text: A telescopic sight is an optical telescope equipped with some form of graphic image pattern reticle mounted in an optically appropriate position in the optical system to give an accurate aiming point. Telescopic sights are used on a wide range of devices including guns, surveying equipment, and even as sights on larger telescopes (called a finderscope).

text: When tracing human lineage back in time, most people look at parents, grandparents, great-grandparents and so on. The same approach is often taken when tracing descendants via children and grandchildren. Dawkins shows that this approach is misguided, as the numbers of ancestors and descendants seem to grow exponentially as generations are added to the lineage tree. In just 80 generations, the number of ancestors can exceed a trillion trillion.

text: To detect dark matter and answer other fundamental questions about our universe, engineers and scientists from all over the world built the Alpha Magnetic Spectrometer (AMS), which NASA compares to the Hubble space telescope, and says could not be accommodated on a free flying satellite platform partly because of its power requirements and data bandwidth needs. On 3 April 2013, NASA scientists reported that hints of dark matter may have been detected by the Alpha Magnetic Spectrometer. According to the scientists, "The first results from the space-borne Alpha Magnetic Spectrometer confirm an unexplained excess of high-energy positrons in Earth-bound cosmic rays."

text: As wavelengths become longer, it becomes easier to use antenna technology to interact with electromagnetic radiation (although it is possible to make very tiny antenna). The near-infrared can be collected much like visible light, however in the far-infrared and submillimetre range,  telescopes can operate more like a radio telescope. For example, the James Clerk Maxwell Telescope observes from wavelengths from 3 μm (0.003 mm) to 2000 μm (2 mm), but uses a parabolic aluminum antenna. On the other hand, the Spitzer Space Telescope, observing from about 3 μm (0.003 mm) to 180 μm (0.18 mm) uses a mirror (reflecting optics). Also using reflecting optics, the Hubble Space Telescope with Wide Field Camera 3 can observe in the frequency range from about 0.2 μm (0.0002 mm) to 1.7 μm (0.0017 mm) (from ultra-violet to infrared light).

text: Balle, Campbell, Keenan  and Flygare demonstrated that the FTMW technique can be applied within a "free space cell" comprising an evacuated chamber containing a Fabry-Perot cavity. This technique allows a sample to be probed only milliseconds after it undergoes rapid cooling to only a few kelvins in the throat of an expanding gas jet. This was a revolutionary development because (i) cooling molecules to low temperatures concentrates the available population in the lowest rotational energy levels. Coupled with benefits conferred by the use of a Fabry-Perot cavity, this brought a great enhancement in the sensitivity and resolution of spectrometers along with a reduction in the complexity of observed spectra; (ii) it became possible to isolate and study molecules that are very weakly bound because there is insufficient energy available for them to undergo fragmentation or chemical reaction at such low temperatures. William Klemperer was a pioneer in using this instrument for the exploration of weakly bound interactions. While the Fabry-Perot cavity of a Balle-Flygare FTMW spectrometer can typically be tuned into resonance at any frequency between 6 and 18 GHz, the bandwidth of individual measurements is restricted to about 1 MHz. An animation illustrates the operation of this instrument which is currently the most widely used tool for microwave spectroscopy.

text: Joshua Bloom of the University of California, Berkeley, who was able to observe the location of the GRB at the Gemini South telescope in Chile, called the discovery of GRB 090423 a "watershed event" as it marked "the beginning of the study of the universe as it was before most of the structure that we know about today came into being."<ref name='New Scientist' /> Nial Tanvir, who was part of the VLT team, suggests that gamma-ray bursts provide a unique tool to study the universe at early times because everything else is too faint to be observed. For instance, the first generation of stars have yet to be directly observed, but the progenitor of GRB 090423 may belong to this class. These early stars are expected to contribute to the reionisation of the universe, a process which ended at a redshift of about 6. As more powerful telescopes begin operation, such as the James Webb Space Telescope that is set to launch in 2018, astronomers hope to pinpoint the locations of faint GRB host galaxies by observing blasts similar to that of GRB 090423.<ref name='New Scientist' />

text: The Víctor M. Blanco Telescope, also known as the Blanco 4m, is a 4-metre aperture telescope located at the Cerro Tololo Inter-American Observatory, Chile. Commissioned in 1974 and completed in 1976, this telescope is similar to the Mayall 4m telescope located on Kitt Peak. In 1995 it was dedicated and named in honour of Puerto Rican astronomer Víctor Manuel Blanco.It was the largest optical telescope in the Southern hemisphere from 1976 until 1998, when the first 8-metre telescope of the ESO Very Large Telescope opened.

text: MOP drew the attention of the United States Congress, where the program was ridiculed and canceled one year after its start. SETI advocates continued without government funding, and in 1995 the nonprofit SETI Institute of Mountain View, California resurrected the MOP program under the name of Project "Phoenix", backed by private sources of funding. Project Phoenix, under the direction of Jill Tarter, is a continuation of the targeted search program from MOP and studies roughly 1,000 nearby Sun-like stars. From 1995 through March 2004, Phoenix conducted observations at the  Parkes radio telescope in Australia, the  radio telescope of the National Radio Astronomy Observatory in Green Bank, West Virginia, and the  radio telescope at the Arecibo Observatory in Puerto Rico. The project observed the equivalent of 800 stars over the available channels in the frequency range from 1200 to 3000 MHz. The search was sensitive enough to pick up transmitters with 1 GW EIRP to a distance of about 200 light-years. According to Prof. Tarter, in 2012 it costs around "$2 million per year to keep SETI research going at the SETI Institute" and approximately 10 times that to support "all kinds of SETI activity around the world."

text: Shortly after the telescope was originally completed, Lovell and Husband started contemplating the idea of upgrading the telescope so that it had a more accurate surface, and was controlled by a digital computer. Plans for this upgrade were created by Husband and Co., and were presented to Lovell in April 1964. Their plans became more urgent when fatigue cracks were discovered in the elevation drive system in September 1967. The telescope was only expected to have an operational lifespan of 10 years, and Husband had been warning about the decay of the telescope since 1963. The appearance of fatigue cracks was the first of these problems that threatened to stop the telescope working; had they been left in place, then the elevation system could have failed and perhaps jammed. The telescope was therefore repaired and upgraded to become the Mark IA; the £400,000 of funding to do this was announced on 8 July 1968 by the SRC to upgrade and repair the telescope to the Mark IA. The upgrade was carried out in three phases, phase 1 lasting between September 1968 and February 1969, phase 2 between September and November 1969 and phase 3 between August 1970 and November 1971.

text: ESO operates three major optical and near infrared telescopes at the La Silla site: the New Technology Telescope (NTT), the 3.6-m ESO Telescope, and the 2.2-m Max-Planck-ESO Telescope (MPG/ESO Telescope). In addition La Silla hosts several other national and project telescopes such as the ESO 1-metre Schmidt Telescope, the 1.54-m Danish Telescope, the 1.2-m Leonhard Euler Telescope, the Rapid Eye Mount telescope, TRAPPIST and TAROT. These telescopes are not operated by ESO and hence do not fall under the responsibility of La Silla Science Operations.

text: For snipers, Karabiner 98k rifles selected for being exceptionally accurate during factory tests were fitted with a telescopic sight as sniper rifles. Karabiner 98k sniper rifles had an effective range of up to  when used by a skilled sniper. The German Zeiss Zielvier 4x (ZF39) telescopic sight had bullet drop compensation in  increments for ranges from  or in some variations from . There were ZF42, Zeiss Zielsechs 6x and Zielacht 8x telescopic sights by various manufacturers like the Ajack 4x and 6x, Hensoldt Dialytan 4x and Kahles Heliavier 4x with similar features employed on Karabiner 98k sniper rifles. Several different mountings produced by various manufacturers were used. The Karabiner 98k was not designed to accept telescopic sights. Attaching such sights to a Karabiner 98k required machining by a skilled armourer. A telescopic sight mounted low above the center axis of the receiver will not leave enough space between the rifle and the telescopic sight body for unimpaired operation of the bolt handle or the three-position safety catch lever. This ergonomic problem was solved by mounting the telescopic sight relatively high above the receiver and sometimes modifying or replacing the safety operating lever or using an offset mounting to position the telescopic sight axis to the left side in relation to the receiver center axis. A common minor modification was replacing the stock buttplate with a waffled anti-slip "sniper" buttplate. Approximately 132,000 of these sniper rifles were produced by Germany.

text: Square waves are universally encountered in digital switching circuits and are naturally generated by binary (two-level) logic devices. They are used as timing references or "clock signals", because their fast transitions are suitable for triggering synchronous logic circuits at precisely determined intervals. However, as the frequency-domain graph shows, square waves contain a wide range of harmonics; these can generate electromagnetic radiation or pulses of current that interfere with other nearby circuits, causing noise or errors. To avoid this problem in very sensitive circuits such as precision analog-to-digital converters, sine waves are used instead of square waves as timing references.

text: Some people who fall into this category can use their considerable residual vision – their remaining sight – to complete daily tasks without relying on alternative methods. The role of a low vision specialist (optometrist or ophthalmologist) is to maximize the functional level of a patient's vision by optical or non-optical means. Primarily, this is by use of magnification in the form of telescopic systems for distance vision and optical or electronic magnification for near tasks.

text: With the advent and growth of organized amateur astronomical groups,  sidewalk astronomy has come to be associated with public education about astronomy via free public viewing for anyone who wishes to look through the telescope. This usually involves individual or a groups of amateur astronomers with small-to-medium-sized telescopes. Organizations such as the San Francisco Sidewalk Astronomers, founded by John Dobson, are organized around the idea of educating people about the universe they live in by having them look through telescopes. Dobson even promoted a design for large inexpensive reflecting telescope that he called a "Sidewalk Telescope", more commonly referred to as the Dobsonian telescope.

text: Radio frequency radiation is usually measured in kilohertz (kHz), megahertz (MHz), or gigahertz (GHz). Light is electromagnetic radiation that is even higher in frequency, and has frequencies in the range of tens (infrared) to thousands (ultraviolet) of terahertz. Electromagnetic radiation with frequencies in the low terahertz range, (intermediate between those of the highest normally usable radio frequencies and long-wave infrared light), is often called terahertz radiation. Even higher frequencies exist, such as that of gamma rays, which can be measured in exahertz. (For historical reasons, the frequencies of light and higher frequency electromagnetic radiation are more commonly specified in terms of their wavelengths or photon energies: for a more detailed treatment of this and the above frequency ranges, see electromagnetic spectrum.)

text: , it should be emphasized that Bradley's result does not merely give the classical limit of the relativistic case, in the sense that it gives incorrect predictions even at low relative velocities. Bradley's explanation cannot account for situations such as the water telescope, nor for many other optical effects (such as interference) that might occur within the telescope. This is because in the Earth's frame it predicts that the direction of propagation of the light beam in the telescope is not normal to the wavefronts of the beam, in contradiction with Maxwell's theory of electromagnetism. It also does not preserve the speed of light c between frames. However, Bradley did correctly infer that the effect was due to relative velocities.

text: One of the key aims of the astronomers who designed the Hubble Space Telescope was to use its high optical resolution to study distant galaxies to a level of detail that was not possible from the ground. Positioned above the atmosphere, Hubble avoids atmospheric airglow allowing it to take more sensitive visible and ultraviolet light images than can be obtained with seeing-limited ground-based telescopes (when good adaptive optics correction at visible wavelengths becomes possible, 10 m ground-based telescopes may become competitive). Although the telescope's mirror suffered from spherical aberration when the telescope was launched in 1990, it could still be used to take images of more distant galaxies than had previously been obtainable. Because light takes billions of years to reach Earth from very distant galaxies, we see them as they were billions of years ago; thus, extending the scope of such research to increasingly distant galaxies allows a better understanding of how they evolve.

text: Radio astronomy began in 1931 when Karl Jansky discovered that the Milky Way was a source of radio emission while doing research on terrestrial static with a direction antenna. Building on Jansky's work, Grote Reber built a more sophisticated purpose-built radio telescope in 1937, with a  dish; using this, he discovered various unexplained radio sources in the sky. Interest in radio astronomy grew after the Second World War when much larger dishes were built including: the  Jodrell bank telescope (1957), the  Green Bank Telescope (1962), and the  Effelsberg telescope (1971). The huge  Arecibo telescope (1963) is so large that it is fixed into a natural depression in the ground; the central antenna can be steered to allow the telescope to study objects up to twenty degrees from the zenith. However, not every radio telescope is of the dish type. For example, the Mills Cross Telescope (1954) was an early example of an array which used two perpendicular lines of antennae  in length to survey the sky.

text: Auction theory is an applied branch of economics which deals with how people act in auction markets and researches the properties of auction markets. There are many possible designs (or sets of rules) for an auction and typical issues studied by auction theorists include the efficiency of a given auction design, optimal and equilibrium bidding strategies, and revenue comparison. Auction theory is also used as a tool to inform the design of real-world auctions; most notably auctions for the privatization of public-sector companies or the sale of licenses for use of the electromagnetic spectrum.

text: In optical astronomy the air mass provides an indication of the deterioration of the observed image, not only as regards direct effects of spectral absorption, scattering and reduced brightness, but also an aggregation of visual aberrations, e.g. resulting from atmospheric turbulence, collectively referred to as the quality of the seeing. On bigger telescopes, such as the WHT (Wynne and Warsick 1988) and VLT (Avila, Rupprecht, and Becker 1997), the atmospheric dispersion can be so severe that it affects the pointing of the telescope to the target. In such cases an atmospheric dispersion compensator is used, which usually consists of two The Greenwood frequency and Fried parameter, both relevant for adaptive optics depend on the air mass above them (or more specifically, on the zenith angle).

text: In other experiments that spring and summer Lodge put a series of spark gaps along two 29 meter long wires and noticed he was getting a very large spark in the gap near the end of the wires, which seemed to be consistent with the oscillation wavelength produced by the Leyden jar meeting with the wave being reflected at the end of the wire. In a darkened room, he also noted a glow at intervals along the wire at one half wavelength intervals. He took this as evidence that he was generating and detecting Maxwell's electromagnetic waves. While on summer vacation Lodge learned that Heinrich Hertz in Germany had been conducting his own electromagnetic research and published a series of papers proving the existence of electromagnetic waves and their propagation in free space. Lodge presented his own paper on electromagnetic waves along wires in September 1888 at the British Science Association meeting in Bath, England, adding a postscript acknowledging Hertz's work and saying: "The whole subject of electrical radiation seems working itself out splendidly."

text: The TNG is an altazimuthal reflecting telescope with a Ritchey-Chretien optical configuration and a flat tertiary mirror feeding two opposite Nasmyth foci. It has a design derived from the New Technology Telescope (NTT), an ESO 4-meters class telescope located in La Silla (Chile). Therefore, the optical quality of the telescope is ensured by an active optics system performing real-time corrections of the optical components and compensating, in particular, for the deformations of the primary mirror, which is too thin to be completely rigid.

text: The 3.67-meter telescope, known as the Advanced Electro-Optical System (AEOS), owned by the Department of Defense, is the United States' largest optical telescope designed for tracking satellites. The 75-ton AEOS telescope points and tracks very accurately, yet is fast enough to track both low-Earth satellites and ballistic missiles. AEOS can be used simultaneously by many groups or institutions because its light can be channeled through a series of mirrors to seven independent coudé rooms below the telescope. Employing sophisticated sensors that include an adaptive optics system, radiometer, spectrograph, and long-wave infrared imager, the telescope tracks man-made objects in deep space and performs space object identification data collection.

text: During the development of radio, many scientists and inventors contributed to radio technology and electronics. The mathematical work of James Clerk Maxwell during the 1850s had shown the relationship of different forms of electromagnetic radiation including possibility of invisible airborne waves (later called "radio waves"). In his classic physics experiments of 1888, Heinrich Hertz proved Maxwell's theory by transmitting radio waves with a spark-gap transmitter, and detected them by using simple electrical devices. Other physicists experimented with these new waves and in the process developed devices for transmitting and detecting them. In 1895, Guglielmo Marconi began work on a way to adapt the known methods of transmitting and detecting these "Hertzian waves" into a purpose built commercial wireless telegraphic system. Early on, he sent wireless signals over a distance of one and a half miles. In December 1901, he sent wireless waves that were not affected by the curvature of the Earth. Marconi later transmitted the wireless signals across the Atlantic between Poldhu, Cornwall, and St. John's, Newfoundland, a distance of .

text: Galileo Galilei was recently selected as a main motif for a high value collectors' coin: the €25 International Year of Astronomy commemorative coin, minted in 2009. This coin also commemorates the 400th anniversary of the invention of Galileo's telescope. The obverse shows a portion of his portrait and his telescope. The background shows one of his first drawings of the surface of the moon. In the silver ring other telescopes are depicted: the Isaac Newton Telescope, the observatory in Kremsmünster Abbey, a modern telescope, a radio telescope and a space telescope. In 2009, the Galileoscope was also released. This is a mass-produced, low-cost educational  telescope with relatively high quality.

text: In addition, Maxwell's equations required that all electromagnetic waves in vacuum propagate at a fixed speed, c. As this can only occur in one reference frame in Newtonian physics (see Galilean-Newtonian relativity), the aether was hypothesized as the absolute and unique frame of reference in which Maxwell's equations hold. That is, the aether must be "still" universally, otherwise c would vary along with any variations that might occur in its supportive medium. Maxwell himself proposed several mechanical models of aether based on wheels and gears, and George Francis FitzGerald even constructed a working model of one of them. These models had to agree with the fact that the electromagnetic waves are transverse but never longitudinal.

text: Although specialized and experienced amateur astronomers tend to acquire more specialized and more powerful equipment over time, relatively simple equipment is often preferred for certain tasks.  Binoculars, for instance, although generally of lower power than the majority of telescopes, also tend to provide a wider field of view, which is preferable for looking at some objects in the night sky.

text: Reber Radio Telescope is a parabolic radio telescope built by astronomer Grote Reber in his back yard in Illinois in 1937, implementing an earlier proposal of Karl Jansky, the discoverer (1931) of radio waves emanating from the Milky Way.   It was the second radio telescope ever built (after Jansky's dipole array), and the first parabolic radio telescope, serving as a prototype for the first large dish radio telescopes such as the Green Bank Telescope and Lovell Telescope constructed after World War 2.  Made of sheet metal with a 31.4 foot (9 meter) aperture and 20 foot (6 meter) focal length, it was the largest parabolic dish in existence at the time.   Reber was the world's only radio astronomer at the time, and his construction of the telescope and the sky surveys he did with it helped found the field of radio astronomy, revealing radio sources such as Cassiopeia A and Cygnus X-1 for the first time.

text: The difficulty of construction is another factor in an amateur’s choice of project. For a given design the difficulty of construction grows roughly as the square  of the diameter of the objective. For example, a Newtonian telescope of  aperture is a moderately easy science fair project. A  Newtonian is considered a good compromise size since construction is not difficult and results in an instrument that would be expensive to purchase commercially. A  reflecting telescope is difficult, but still within the ability of the average amateur who has had experience building smaller instruments. Amateurs have constructed telescopes as large as  across, but usually small groups or astronomy clubs take on such projects.

text: The Institut de radioastronomie millimétrique (IRAM) operates two radio astronomy telescopes at millimeter wavelengths, which are open to the international astronomical community: the 30 m single-dish radio telescope located on Pico Veleta (2850 m) in the Spanish Sierra Nevada (Andalucia, Spain), and the six-antenna Plateau de Bure Interferometer (2550 m) in the French Alps. Both sites are at high altitude to reduce the absorption by water vapor. The telescopes are supported by the IRAM offices and laboratories in Granada and Grenoble, respectively. IRAM, which is directed by Karl Schuster, has its headquarters in Grenoble.

text: On the longer term, after accomplishing the primary goal of discovering gravitational waves, Virgo aims at being part of the birth of a new branch of astronomy by observing the Universe with a different and complementary perspective than current telescopes and detectors. Information brought by gravitational waves will be added to those provided by the study of the electromagnetic spectrum (microwaves, radio waves, infrared, the visible spectrum, ultraviolet, X rays and gamma rays), of cosmic rays and of neutrinos. In order to correlate a gravitational wave detection with visible and localized events in the sky, the LIGO and VIRGO collaborations have signed bilateral agreements with many teams operating telescopes to quickly inform (on the timescale of a few days or a few hours) these partners that a potential gravitational wave signal has been observed. These alerts must be sent before knowing whether the signal is real or not, because the source (if it is real) may only remain visible during a short amount of time.

text: The Submillimeter Telescope (SMT), formerly known as the Heinrich Hertz Submillimeter Telescope, is a submillimeter wavelength radio telescope located on Mount Graham, Arizona.  It is a 10-meter-wide parabolic dish inside a building to protect it from bad weather. The building front doors and roof are opened when the telescope is in use.  The telescope's construction was finished in 1993.  Along with the 12 Meter Telescope on Kitt Peak, this telescope is maintained by the Arizona Radio Observatory, a division of Steward Observatory at the University of Arizona.

text: At nearly  distant, Kepler-452b is too remote and its star too far for current telescopes or the next generation of planned telescopes to determine its true mass or whether it has an atmosphere. The Kepler spacecraft focused on a single small region of the sky but next-generation planet-hunting space telescopes, such as TESS and CHEOPS, will examine nearby stars throughout the sky. Nearby stars with planets can then be studied by the upcoming James Webb Space Telescope and future large ground-based telescopes to analyze atmospheres, determine masses and infer compositions. Additionally the Square Kilometer Array would significantly improve radio observations over the Arecibo Observatory and Green Bank Telescope.

text: Mt. Abu Observatory is equipped with a 1.2m Infrared Telescope along with the following back-end instruments: NICMOS Infrared Camera and Spectrograph, Imaging Fabry-Perot Spectrometer, large format optical CCDs, Optical Imaging Polarimeter and Fibre-linked Grating Spectrograph. A new high resolution optical spectrometer, PRL Advanced Radial-velocity All-sky Search (PARAS) to detect extrasolar planets using the radial velocity technique began observation in April 2012.In addition to these, a 50 cm telescope, Automated Telescope for Variability Study (ATVS), is now functional to monitor variable sources, eg AGNs, variable stars, Comets etc. MIRO has its own aluminizing plant for polishing of the telescope mirrors, a liquid nitrogen plant for providing liquid nitrogen to cool the IR detectors to reduce thermal noise.A new facility, created by LEOS, ISRO will become operational next year. This facility will have a one-metre diameter telescope with sophisticated optics and back-end instruments assembled by the Laboratory for Electro-Optics Systems (LEOS), Bengaluru.  The new facility, known as the Electro-Optical Deep Space Surveillance (EODSS) system, will track space debris,  mainly consisting of inactive satellites, electronic parts of instruments, leftovers from rocket launch and other such junk in space.  It will help ISRO to better handle their future missions, including re-entry capable space shuttles.

text: The observatory is also equipped with a more modern and more powerful instrument - a Celestron C14. It is a telescope which works with mirrors, as is generally the case with per-formant instruments. This one is a Schmidt-Cassegrain - that is, it has a hyperbolic and concave secondary mirror in the same axis as the primary mirror, which reflects light back through a hole pierced in the primary mirror itself. The image can then be observed through an eyepiece at the end of the tube. This instrument, with a primary mirror of 40 cm diameter can capture about 1800 times more light than the naked eye; the diameter of the eye's pupil is only 5 mm. In order to increase the stability of the instrument we have opted for a German mount. The electronic pilot automatically follows observed objects by compensating for the rotation of the Earth. Our NGC-Max guiding system contains the coordinates of thousands of objects and greatly helps with the aiming of the telescope.

text: The Synthesis Telescope consists of seven nine-metre, metal-mesh reflector antennas along a 600-m east-west baseline. The antennas are equipped with single-circular polarisation receivers at 408 MHz and dual circular receivers at 1420 MHz, from which all four Stokes parameters may be formed. A spectrometer may also be employed at 1420 MHz for study of the 21-cm hydrogen line. Maps of the sky are formed using the technique of aperture synthesis.

text: The Hilda Lindley House was built by the Army at a cost of about $22,000. The two-story structure, standing on a hill about 87 feet above mean low tide and approximately a half-mile back from the beach, contained two instrument rooms on the ground floor and another instrument room on the second floor, where soldiers used azimuth telescopes to look for enemy shipping on Block Island Sound. The soldiers looked through the fire control station’s characteristic mullioned observation slots — long, narrow windows with vertical supports.

text: John Dobson was most notable for being the originator and promoter of a design for a large, portable, low-cost reflecting telescope, the "Dobsonian telescope". The design is a very simple, low cost alt-azimuth mounted Newtonian telescope that employs common materials such as plywood, formica, PVC closet flanges, cardboard construction tubes, recycled porthole glass, and indoor-outdoor carpet. This type of simplified altazimuth mount is also commonly referred to in amateur astronomical circles as a "Dobsonian mount". Using this construction method makes the typical Dobsonian telescope large, portable, inexpensive, very stable, and easy to manufacture. The design revolutionized the sheer size of telescopes available to amateur astronomers with the optical diameters unheard of before their appearance.

text: A main feature on the grounds of the castle is the "Great Telescope" or Leviathan (aka The Rosse Telescope) of the third Earl of Rosse, an astronomical telescope with a 183-cm (72 in) reflector. It was completed in 1845 and was used for several decades before the last observations were made in the first years of the 20th century. Its record size was not surpassed until the completion of the 100-inch (2.5-meter) Hooker Telescope at Mount Wilson Observatory in 1917. It was dismantled in 1914, but the structure was restored and the telescope reconstructed in the 1990s and is open to the public.

text: The telescopes amateur telescope makers build range from backyard variety to sophisticated instruments that make meaningful contributions to the field of astronomy. Instruments built by amateurs have been employed in planetary study, astrometry, photometry, comet and asteroid discovery to name just a few. Even the “hobbyist” end of the field can break down into several distinct categories such as: observing deep sky objects, observing the planets, solar observing, lunar observation, and astrophotography of all those classes of objects. Therefore, the design, size, and construction of the telescopes vary as well. Some amateur telescope makers build instruments that, while looking crude, are wholly suited to the purpose they are designed for. Others may strive for a more aesthetic look with high levels of mechanical “finish”. Since some amateur telescope makers do not have access to high-precision machining equipment, many elegant designs such as the Poncet Platform, Crayford focuser, and the Dobsonian telescope have evolved, which achieve functionality and stability without requiring precision machining.

text: Kepler-10b's discovery was based on eight months of data collected with the Kepler telescope from May 2009 to January 2010. The planet's first transits were observed in July 2009. According to the collected data, Kepler-10 dimmed by one part in ten thousand every 0.83 days. Kepler-10 was the first star in the field of view of the Kepler telescope identified as capable of harboring a small transiting planet, and was considered a high priority target for ground based radial velocity observations intended to confirm the mass of Kepler-10b. Radial velocity measurements with the Keck I telescope taken intermittently between August 2009 and August 2010 revealed a periodic Doppler shift in the spectrum of Kepler-10 consistent with a planet of the nature observed by Kepler, confirming the planet's existence and allowing its mass to be determined. The planet's discovery was announced to the public on January 10, 2011.

text: Based only on uncertain descriptions of the first practical telescope which Hans Lippershey tried to patent in the Netherlands in 1608, Galileo, in the following year, made a telescope with about 3x magnification. He later made improved versions with up to about 30x magnification. With a Galilean telescope, the observer could see magnified, upright images on the earth—it was what is commonly known as a terrestrial telescope or a spyglass. He could also use it to observe the sky; for a time he was one of those who could construct telescopes good enough for that purpose. On 25 August 1609, he demonstrated one of his early telescopes, with a magnification of about 8 or 9, to Venetian lawmakers. His telescopes were also a profitable sideline for Galileo, who sold them to merchants who found them useful both at sea and as items of trade. He published his initial telescopic astronomical observations in March 1610 in a brief treatise entitled Sidereus Nuncius (Starry Messenger).

text: In cognitive psychology, the telescoping effect (or telescoping bias) refers to the temporal displacement of an event whereby people perceive recent events as being more remote than they are and distant events as being more recent than they are. The former is known as backward telescoping or time expansion, and the latter as is known as forward telescoping. Three years is approximately the time frame in which events switch from being displaced backwards in time to forwards in time, with events occurring three years in the past being equally likely to be reported with forward telescoping bias as with backward telescoping bias. Although telescoping occurs in both the forward and backward directions, in general the effect is to increase the number of events reported too recently. This net effect in the forward direction is because of forces that impair memory, such as lack of salience, also impair time perception. Telescoping leads to an over reporting of the frequency of events. This over reporting is because participants include events beyond the period, either events that are too recent for the target time period (backward telescoping) or events that are too old for the target time period (forward telescoping).

This over reporting is because participants include events beyond the period, either events that are too recent for the target time period (backward telescoping) or events that are too old for the target time period (forward telescoping).

text: Then on October 18, 1916, University President Rufus von KleinSmid announced that an anonymous donor had given the University $60,000 “…to be used to buy a telescope of huge size.”  That donor was later revealed to be Mrs. Lavinia Steward of Oracle, Arizona.  Mrs. Steward was a wealthy widow who had an interest in astronomy and a desire to memorialize her late husband, Mr. Henry Steward.  Douglass made plans to use the Steward gift to construct a 36-inch diameter Newtonian reflecting telescope.  The Warner & Swasey Company of Cleveland, Ohio was contracted to build the telescope, but the United States entry into World War I delayed the contract since Warner & Swayze had war contracts that took priority.  The situation was further delayed by the fact that up until this time, the expertise in large telescope mirror making was in Europe.  The war made it impossible to contract with a European company.  So Douglass had to find an American glass company that was willing to develop this expertise.  After a couple of failed castings, the Spencer Lens Co. of Buffalo, New York ultimately produced a 36-inch mirror for the Steward Telescope.

text: Isaac Newton (1643–1727) investigated the refraction of light, demonstrating that a prism could decompose white light into a spectrum of colours, and that a lens and a second prism could recompose the multicoloured spectrum into white light. He also showed that the coloured light does not change its properties by separating out a coloured beam and shining it on various objects. Newton noted that regardless of whether it was reflected or scattered or transmitted, it stayed the same colour. Thus, he observed that colour is the result of objects interacting with already-coloured light rather than objects generating the colour themselves. This is known as Newton's theory of colour. From this work he concluded that any refracting telescope would suffer from the dispersion of light into colours, and invented a reflecting telescope (today known as a Newtonian telescope) to bypass that problem. By grinding his own mirrors, using Newton's rings to judge the quality of the optics for his telescopes, he was able to produce a superior instrument to the refracting telescope, due primarily to the wider diameter of the mirror. In 1671 the Royal Society asked for a demonstration of his reflecting telescope. Their interest encouraged him to publish his notes On Colour, which he later expanded into his Opticks. Newton argued that light is composed of particles or corpuscles and were refracted by accelerating toward the denser medium, but he had to associate them with waves to explain the diffraction of light (Opticks Bk. II, Props. XII-L). Later physicists instead favoured a purely wavelike explanation of light to account for diffraction. Today's quantum mechanics, photons and the idea of wave-particle duality bear only a minor resemblance to Newton's understanding of light.

text: The telescope was calibrated to only record gamma rays entering the telescope at certain angles. As these gamma rays entered the telescope, the rays went through the telescopes spark chamber and started the production of an electron and positron. The calorimeter then detected the electron or positron and recorded its data, such as energy level.

text: Space-based observatories are telescopes or other instruments that are located in outer space, many in orbit around the Earth. Space telescopes can be used to observe astronomical objects at wavelengths of the electromagnetic spectrum that cannot penetrate the Earth's atmosphere and are thus impossible to observe using ground-based telescopes. The Earth's atmosphere is opaque to ultraviolet radiation, X-rays, and gamma rays and is partially opaque to infrared radiation so observations in these portions of the electromagnetic spectrum are best carried out from a location above the atmosphere of our planet. Another advantage of space-based telescopes is that, because of their location above the Earth's atmosphere, their images are free from the effects of atmospheric turbulence that plague ground-based observations. As a result, the angular resolution of space telescopes such as the Hubble Space Telescope is often much smaller than a ground-based telescope with a similar aperture. However, all these advantages do come with a price. Space telescopes are much more expensive to build than ground-based telescopes. Due to their location, space telescopes are also extremely difficult to maintain. The Hubble Space Telescope was serviced by the Space Shuttle while many other space telescopes cannot be serviced at all.

text: Most amateur astronomers work at visible wavelengths, but a small minority experiment with wavelengths outside the visible spectrum.  An early pioneer of radio astronomy was Grote Reber, an  amateur astronomer who constructed the first purpose built radio telescope in the late 1930s to follow up on the discovery of radio wavelength emissions from space by Karl Jansky.  Non-visual amateur astronomy includes the use of infrared filters on conventional telescopes, and also the use of radio telescopes.  Some amateur astronomers use home-made radio telescopes, while others use radio telescopes that were originally built for astronomy research but have since been made available for use by amateurs.  The One-Mile Telescope is one such example.

text: There are many applications for ULE, but by far the most common is for mirrors and lenses for telescopes in both space and terrestrial settings. One of the most well known examples of the use of ULE is in the Hubble telescope's mirror. Another good example of its application is in the Gemini telescope's mirror bank. this type of material is needed for this application because the mirrors on telescopes, especially the very large and precise ones, cannot bend or lose their shape even slightly. If this were to happen, the telescope would be out of focus. some other examples and uses of ULE are:

text: In his 1663 Optica Promota, James Gregory described his reflecting telescope which has come to be known by his name, the Gregorian telescope. Gregory pointed out that a reflecting telescope with a parabolic mirror would correct spherical aberration as well as the chromatic aberration seen in refracting telescopes. In his design he also placed a concave secondary mirror with an elliptical surface past the focal point of the parabolic primary mirror, reflecting the image back through a hole in the primary mirror where it could be conveniently viewed. According to his own confession, Gregory had no practical skill and he could find no optician capable of actually constructing one.

text: Space telescopes. Since the beginning of space exploration, telescopes have been sent to space, where they work at wavelengths shorter than UV, which are completely absorbed by the atmosphere, and where flares may be very bright. Since the 1970s, the GOES series of satellites observe the Sun in soft X-rays, and their observations became the standard measure of flares, diminishing the importance of the Hα classification. Hard X-rays were observed by many different instruments, the most important today being the Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI). Nonetheless, UV observations are today the stars of solar imaging with their incredible fine details that reveal the complexity of the solar corona. Spacecraft may also bring radio detectors at extremely long wavelengths (as long as a few kilometers) that cannot propagate through the ionosphere.

text: The Ritchey-Chrétien is a specialized Cassegrain reflector which has two hyperbolic mirrors (instead of a parabolic primary). It is free of coma and spherical aberration at a flat focal plane, making it well suited for wide field and photographic observations. It was invented by George Willis Ritchey and Henri Chrétien in the early 1910s. This design is very common in large professional research telescopes, including the Hubble Space Telescope, Keck Telescopes and VLT telescope; it is also found in high-grade amateur telescopes.

text: The scientific instruments consisted of an ion chamber and Geiger-Müller tube to measure total radiation flux, a proportional radiation counter telescope to measure high energy radiation, a scintillation counter to monitor low-energy radiation, a VLF receiver for natural radio waves, a transponder to study electron density, and part of the flux-gate and search coil magnetometers mounted on the instrument platform. The micrometeorite detector and sun scanner were mounted on the sphere. The difference between the payload of Pioneer P-30 and the earlier Pioneer P-3 was the replacement of the TV facsimile system on P-3 with a scintillation spectrometer to study the Earth's (and possible lunar) radiation belts, mounted on the instrument platform, and a plasma probe mounted on the sphere to measure energy and momentum distribution of protons above a few kilovolts to study the radiation effect of solar flares. The total mass of the science package including electronics and power supply was roughly . Total cost of the mission was estimated at 9-10 million dollars.

text: The following is a list of largest single mount optical telescopes sorted by total objective diameter (aperture), including segmented and multi-mirror configurations. It is a historical list, with the instruments listed in chronological succession by objective size. By itself, the diameter of the primary optics can be a poor measure of a telescope's historical or scientific significance; for example, William Parsons, 3rd Earl of Rosse's 72-inch (1.8 m) reflecting telescope did not perform as well (i.e. gather as much light) as the smaller silvered glass mirror telescopes that succeeded it because of the poor performance of its speculum metal mirror.

text: Another way to measure the speed of light is to independently measure the frequency f and wavelength λ of an electromagnetic wave in vacuum. The value of c can then be found by using the relation c = fλ. One option is to measure the resonance frequency of a cavity resonator. If the dimensions of the resonance cavity are also known, these can be used to determine the wavelength of the wave. In 1946, Louis Essen and A.C. Gordon-Smith established the frequency for a variety of normal modes of microwaves of a microwave cavity of precisely known dimensions. The dimensions were established to an accuracy of about ±0.8 μm using gauges calibrated by interferometry. As the wavelength of the modes was known from the geometry of the cavity and from electromagnetic theory, knowledge of the associated frequencies enabled a calculation of the speed of light.

text: The ALFALFA survey is a blind extragalactic survey in neutral atomic hydrogen (HI) utilizing the ALFA at Arecibo Observatory. The telescope is not directed at preselected targets, but at one location for one night, allowing the sky to pass. This is called drift-scan. The goal is to find up to 25,000 galaxies in the course of 6–7 years. Some of the detected objects should be dark galaxies, consisting largely of dark matter and in this case hydrogen gas, but no or very few stars. These galaxies are not visible with optical telescopes and yet (March 2009) undiscovered.

text: Until the 1940s, Bonn astronomical observations were carried out mainly from Argelander's old observatory in Bonn itself. With more and more electrical lights in the city, the night sky in town became increasingly brighter, making observations difficult. In search for an alternative location, in 1950, the hill of Hoher List above the village of Schalkenmehren was found to be well suited for astronomical observation. The rural surrounds meant very low sky brightness. It was decided to relocate the Bonn telescopes. The new observatory was inaugurated in 1954, after the 50 cm Schmidt telescope had been installed in the first dome. A major extension in 1964 included the relocation of the Double Refractor, which dates from 1899. The final dome to be erected contains a 1 m Cassegrain telescope, the largest and most modern of the observatory's telescopes. Today, there are six telescopes at the observatory. The Double Refractor aside, there is also the 16 cm Schröder Refractor, which was used for the Cordoba Durchmusterung (the southern extension of the Bonner Durchmusterung).

text: Ground-based observatories, located on the surface of Earth, are used to make observations in the radio and visible light portions of the electromagnetic spectrum. Most optical telescopes are housed within a dome or similar structure, to protect the delicate instruments from the elements. Telescope domes have a slit or other opening in the roof that can be opened during observing, and closed when the telescope is not in use. In most cases, the entire upper portion of the telescope dome can be rotated to allow the instrument to observe different sections of the night sky. Radio telescopes usually do not have domes.

text: Following a TV programme, lecture, and book by Patrick Moore, there was renewed interest in the six-foot telescope in the 1970s. Gradually, the telescope became a visitor attraction. But it was not before the 1990s that plans to actually rebuild the telescope came to fruition. In 1994 the retired structural engineer and amateur astronomer Michael Tubridy was called in to research and re-design the Rosse six-foot telescope. The original plans were lost, and so it took detective work to review the remains of the telescope, incidental comments in observing logs, and contemporary photographs taken by Mary Rosse, wife of the 3rd Earl. Reconstruction work lasted from early 1996 to early 1997. It had been planned to include a working mirror, but due to budget constraints this had to be left for a separate project.

text: The KSAR Telescope's 60-foot diameter steel dome is quite large for the telescope's aperture, owing to its telescope's long f/9.8 focal ratio (favorable for very accurate optical collimation, or alignment, needed for astrometric observation). It uses a very wide 2-shutter, vertical slit. Development studies have taken place to successfully show that planned life-cycle replacement of this venerable instrument can be efficiently done within the original dome, for a future telescope with an aperture of up to 3.6-meters, by using fast, modern-day optics. However, the 61-inch telescope remains unique in its ability to operationally conduct both very high-accuracy relative astrometry to the milliarcsecond level, and close-separation, PSF photometry. Several key programs take advantage of this capability to this day.

This telescope was installed in 2008 after the completion of the Loines Observatory. The Loines Observatory houses the historic 7.5-inch Alvan Clark refractor, which is used for public stargazing. At this location there is also the larger 24-inch Richey-Chretian reflecting telescope, installed in 2006, which has been made accessible for public tours.

text: This unification, which was observed by Michael Faraday, extended by James Clerk Maxwell, and partially reformulated by Oliver Heaviside and Heinrich Hertz, is one of the key accomplishments of 19th century mathematical physics. It has had far-reaching consequences, one of which was the understanding of the nature of light. Unlike what was proposed by electromagnetic theory of that time, light and other electromagnetic waves are at present seen as taking the form of quantized, self-propagating oscillatory electromagnetic field disturbances called photons. Different frequencies of oscillation give rise to the different forms of electromagnetic radiation, from radio waves at the lowest frequencies, to visible light at intermediate frequencies, to gamma rays at the highest frequencies.

text: At the microscale, an electromagnetic wave's phase velocity is slowed in a material because the electric field creates a disturbance in the charges of each atom (primarily the electrons) proportional to the electric susceptibility of the medium. (Similarly, the magnetic field creates a disturbance proportional to the magnetic susceptibility.) As the electromagnetic fields oscillate in the wave, the charges in the material will be "shaken" back and forth at the same frequency. The charges thus radiate their own electromagnetic wave that is at the same frequency, but usually with a phase delay, as the charges may move out of phase with the force driving them (see sinusoidally driven harmonic oscillator). The light wave traveling in the medium is the macroscopic superposition (sum) of all such contributions in the material: the original wave plus the waves radiated by all the moving charges. This wave is typically a wave with the same frequency but shorter wavelength than the original, leading to a slowing of the wave's phase velocity. Most of the radiation from oscillating material charges will modify the incoming wave, changing its velocity. However, some net energy will be radiated in other directions or even at other frequencies (see scattering).

text: Coronagraphs in outer space are much more effective than the same instruments would be if located on the ground. This is because the complete absence of atmospheric scattering eliminates the largest source of glare present in a terrestrial coronagraph. Several space missions such as NASA-ESA's SOHO, and NASA's SPARTAN, Solar Maximum Mission, and Skylab have used coronagraphs to study the outer reaches of the solar corona. The Hubble Space Telescope (HST) is able to perform coronagraphy using the Near Infrared Camera and Multi-Object Spectrometer (NICMOS), and there are plans to have this capability on the James Webb Space Telescope (JWST) using its Near Infrared Camera (NIRCam) and Mid Infrared Instrument (MIRI).

text: The Earth's atmosphere is opaque over most of the far-infrared, so that ground-based observations are limited to submillimetre wavelengths using high-altitude telescopes such as the James Clerk Maxwell Telescope, the Caltech Submillimeter Observatory, and the Submillimeter Array. Most far-infrared astronomy is performed by satellites such as the Herschel Space Observatory, Spitzer, IRAS, and ISO. Upper-atmosphere observations are also possible, as conducted by the airborne SOFIA telescope.

text: Interferometry is a technique pioneered by Albert A. Michelson in the 19th century. Optical interferometry, which has matured within the last two decades, combines the light of multiple telescopes so that precise measurements can be made, akin to what might be accomplished with a single, much larger telescope. It is the interaction of light waves, called interference, that makes this possible. Interference can be used to cancel out the glare of bright stars or to measure distances and angles accurately. The construction of the word partially illustrates this: interfere + measure = interfer-o-metry. At radio wavelengths of the electromagnetic spectrum, interferometry has been used for more than 50 years to measure the structure of distant galaxies.

text: After 1640, the Dutch continued to inform the Japanese about the evolution of telescope technology. Until 1676 more than 150 telescopes were brought to Nagasaki.  In 1831, after having spent several months in Edo where he could get accustomed with Dutch wares, Kunitomo Ikkansai (a former gun manufacturer) built Japan’s first reflecting telescope of the Gregorian type. Kunitomo’s telescope had a magnification of 60, and allowed him to make very detailed studies of sun spots and lunar topography. Four of his telescopes remain to this day.

text: During the past century, astronomy has been revolutionized by the use of new methods for observing the universe. Astronomical observations were originally made using visible light. Galileo Galilei pioneered the use of telescopes to enhance these observations. However, visible light is only a small portion of the electromagnetic spectrum, and not all objects in the distant universe shine strongly in this particular band. More useful information may be found, for example, in radio wavelengths. Using radio telescopes, astronomers have found pulsars, quasars, and other extreme objects that push the limits of our understanding of physics. Observations in the microwave band have opened our eyes to the faint imprints of the Big Bang, a discovery Stephen Hawking called the "greatest discovery of the century, if not all time". Similar advances in observations using gamma rays, x-rays, ultraviolet light, and infrared light have also brought new insights to astronomy. As each of these regions of the spectrum has opened, new discoveries have been made that could not have been made otherwise. Astronomers hope that the same holds true of gravitational waves.

text: The ESO New Technology Telescope (NTT) is an Alt-Az, 3.58m Richey-Chretien telescope which pioneered the use of active optics. The telescope and its enclosure had a revolutionary design for optimal image quality. NTT saw first light in March 1989. The telescope chamber is ventilated by a system of flaps which optimize the air flow across the NTT minimizing the dome and mirror seeing. To prevent heat input to the building, all motors in the telescope are water cooled and all the electronics boxes are insulated and cooled. The primary mirror of the NTT is actively controlled to preserve its figure at all telescope positions. The secondary mirror position is also actively controlled in three directions. The optimized airflow, the thermal controls, and the active optics give the excellent image quality of the NTT. Note that the NTT has active instead of adaptive optics: it corrects the defects and deformation of the telescope and mirror, but does not correct the turbulence; it ensures that the optics is always in perfect shape. Together with the thermal control, it allows the NTT to reach the ambient seeing, but it does not improve it.

text: SWAS was designed to study the composition and structure of interstellar clouds and investigate the processes of stellar and planetary formation. Its sole instrument is a telescope operating in the submillimeter wavelengths of far infrared and microwave radiation. The telescope is composed of three main components: a  elliptical off-axis Cassegrain reflector, two Schottky diode receivers, and an acousto-optical spectrometer. The system is sensitive to frequencies between 487–557 GHz (538–616 μm), which allows it to focus on the spectral lines of molecular oxygen (O) at 487.249 GHz; neutral carbon () at 492.161 GHz; isotopic water (HO) at 548.676 GHz; isotopic carbon monoxide (CO) at 550.927 GHz; and water (HO) at 556.936 GHz.

text: It is hard to classify the Dobsonian Telescope as a single invention. In the field of amateur telescope making most, if not all, of its design features had been used before. John Dobson, credited as having invented this design in the 1950s, points out that "for hundreds of years, wars were fought using cannon on 'Dobsonian' mounts". Dobson himself identified the characteristic features of the design as lightweight objective mirrors made of porthole glass, and mountings constructed from plywood, Teflon strips and other low-cost materials. Since he built these telescopes as aids in his avocation of instructional sidewalk astronomy, he prefers to call the design a "sidewalk telescope". It appears that John Dobson simply combined all these innovations in a design that is focused towards one goal: building a very large, inexpensive, easy to use, portable telescope for the sole purpose of visual observing of astronomical objects as a way to bring astronomy to the masses.
