UCL Observatory
UCL Observatory (called the University of London Observatory until 2015) at Mill Hill in London is an astronomical teaching observatory. It is part of the Department of Physics and Astronomy at University College London. History The Observatory was opened, as the University of London Observatory, on 8 October 1929 by the then Astronomer Royal Frank Watson Dyson, initially to house the 24-inch reflector built by Grubb of Dublin in 1881 and housed in Dr W.E. Wilson's observatory at Daramona, County Westmeath, Ireland, which was donated to the University of London after his death. An 8-inch refractor was installed in 1931 following its donation to the University by H.R. Fry of Barnett the previous year, and was named after him. In 1932, the University received a 6-inch refractor telescope from the estate of Mr. John Joynson of Liverpool. Although originally housed in the North dome in the Bloomsbury campus main quad, it was later relocated to the Observatory. In July 1938, the Ob ...

Astronomical Observatories In England
Astronomy () is a natural science that studies celestial objects and phenomena. It uses mathematics, physics, and chemistry in order to explain their origin and evolution. Objects of interest include planets, moons, stars, nebulae, galaxies, and comets. Relevant phenomena include supernova explosions, gamma ray bursts, quasars, blazars, pulsars, and cosmic microwave background radiation. More generally, astronomy studies everything that originates beyond Earth's atmosphere. Cosmology is a branch of astronomy that studies the universe as a whole. Astronomy is one of the oldest natural sciences. The early civilizations in recorded history made methodical observations of the night sky. These include the Babylonians, Greeks, Indians, Egyptians, Chinese, Maya, and many ancient indigenous peoples of the Americas. In the past, astronomy included disciplines as diverse as astrometry, celestial navigation, observational astronomy, and the making of calendars. Nowadays, pr ...

Celestron
Celestron is an American company based in Torrance, California, United States, that manufactures telescopes and distributes telescopes, binoculars, spotting scopes, microscopes, and accessories manufactured by its parent company, the Synta Technology Corporation of Taiwan. History The predecessor of Celestron was Valor Electronics, an electronics and military components firm founded in 1955 by Tom Johnson. Johnson became involved with telescopes when he built a 6" reflecting telescope for his two sons. In 1960, Johnson established the "Astro-Optical" division of Valor, which would later become Celestron. By 1964, Johnson had founded "Celestron Pacific" as a division of Valor Electronics offering Schmidt-Cassegrain telescopes from 4" to 22". In 1970 Celestron introduced its "C8" 8" diameter 2032 mm focal length, ƒ10 telescope, the first of a new line of telescopes built using methods developed by Celestron to produce Schmidt-Cassegrains at a high volume and low cost. These ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steve Fossey
Stephen John Fossey is a British astronomer working at UCL Observatory, which is part of University College London (UCL). He is one of the three editors of ''The Observatory'' magazine. Fossey's research interests are in the interstellar medium, exoplanets and time-domain astronomy. Along with Ingo Waldmann and David Kipping, Fossey discovered in 2009 that the exoplanet HD 80606b (previously known from radial velocity) transits its host star. Fossey also discovered supernova SN 2014J, the closest supernova for each for several decades, in January 2014. Education Fossey studied at University College London (UCL), receiving his Bachelor of Science with Honours in 1983. This was followed in 1990 by a PhD in Astronomy (also at UCL). Fossey later became a member of staff at ULO (University of London Observatory). Research and publications The areas of research that Fossey takes most interest in are extrasolar planets, the interstellar medium, and molecular astrophysics. He has au ...

SN2014J
SN 2014J was a type-Ia supernova in Messier 82 (the 'Cigar Galaxy', M82) discovered in mid-January 2014. It was the closest type-Ia supernova discovered for 42 years, and none have been closer . The supernova was discovered by chance during an undergraduate teaching session at the University of London Observatory. It peaked on 31 January 2014, reaching an apparent magnitude of 10.5. SN 2014J was the subject of an intense observing campaign by professional astronomers and was bright enough to be seen by amateur astronomers. Discovery The supernova was discovered by astronomer Steve Fossey, of University College London and four of his undergraduate students: Ben Cooke, Guy Pollack, Matthew Wilde and Thomas Wright. Fossey was training the students on how to use a small telescope at University of London Observatory, located in Mill Hill, a suburb of north London. The discovery was serendipitous, because Fossey was not searching for supernovae, had not planned to look at M82 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extrasolar Planets
An exoplanet or extrasolar planet is a planet outside the Solar System. The first possible evidence of an exoplanet was noted in 1917 but was not recognized as such. The first confirmation of detection occurred in 1992. A different planet, initially detected in 1988, was confirmed in 2003. There are many methods of detecting exoplanets. Transit photometry and Doppler spectroscopy have found the most, but these methods suffer from a clear observational bias favoring the detection of planets near the star; thus, 85% of the exoplanets detected are inside the tidal locking zone. In several cases, multiple planets have been observed around a star. About 1 in 5 Sun-like starsFor the purpose of this 1 in 5 statistic, "Sun-like" means G-type star. Data for Sun-like stars was not available so this statistic is an extrapolation from data about K-type stars. have an "Earth-sized"For the purpose of this 1 in 5 statistic, Earth-sized means 1–2 Earth radii. planet in the habitable zone. ...

Ritchey–Chrétien Telescope
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. History The Ritchey–Chrétien telescope was invented in the early 1910s by American astronomer George Willis Ritchey and French astronomer Henri Chrétien. Ritchey constructed the first successful RCT, which had an aperture diameter of in 1927 (e.g. Ritchey 24-inch reflector). The second RCT was a instrument constructed by Ritchey for the United States Naval Observatory; that telescope ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mill Hill
Mill Hill is a suburb in the London Borough of Barnet, England. It is situated around northwest of Charing Cross. Mill Hill was in the historic county of Middlesex until 1965, when it became part of Greater London. Its population counted 18,451 inhabitants as of 2011. Mill Hill consists of several distinct parts: the original Mill Hill Village; the later-developed Mill Hill Broadway (now the main hub of the area); and Mill Hill East - alongside large swathes of countryside. A further area at the western edge of the suburb, The Hale, is on the borders of Mill Hill and Edgware, and is partly in each. History The area's name was first recorded as Myllehill in 1547 and appears to mean "hill with a windmill". However, the workings of the original Mill are in the building adjacent to The Mill Field. Mill Hill Village is the oldest known inhabited part of the district, a ribbon development along a medieval route called 'The Ridgeway'. It is thought that the name 'Mill Hill' may ...
