Thomas David Anderson
Thomas David Anderson (6 February 1853 – 31 March 1932) was a Scottish amateur astronomer. Life He was born at 28 Saxe-Coburg Place in Stockbridge, Edinburgh, the son of John Anderson. When he was five years old, his father showed him Comet Donati, and his nanny also gave him an interest in astronomy. He was educated at Edinburgh Institution and the University of Edinburgh where he studied theology, graduating with a DSc in philology in 1880. He abandoned his plans of becoming a minister. He was sufficiently well off financially to pursue astronomy full-time. In 1890 he was living at 3 Alfred Place on the south side of Edinburgh and working as a bank agent for the Bank of Scotland. He became a keen observer, and discovered two fairly well known novas: Nova Aurigae 1892 and Nova Persei 1901. The former marked the first time a nova's spectrum had been photographed, while the latter eventually reached magnitude 0.2 to become the brightest nova in history since the sup ...

Astronomer
An astronomer is a scientist in the field of astronomy who focuses their studies on a specific question or field outside the scope of Earth. They observe astronomical objects such as stars, planets, natural satellite, moons, comets and galaxy, galaxies – in either observational astronomy, observational (by analyzing the data) or theoretical astronomy. Examples of topics or fields astronomers study include planetary science, Sun, solar astronomy, the Star formation, origin or stellar evolution, evolution of stars, or the galaxy formation and evolution, formation of galaxies. A related but distinct subject is physical cosmology, which studies the Universe as a whole. Types Astronomers usually fall under either of two main types: observational astronomy, observational and theoretical astronomy, theoretical. Observational astronomers make direct observations of Astronomical object, celestial objects and analyze the data. In contrast, theoretical astronomers create and investigate C ...

V Cassiopeiae
V, or v, is the twenty-second and fifth-to-last letter in the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''vee'' (pronounced ), plural ''vees''. History The letter V ultimately comes from the Phoenician letter ''waw'' by way of U. See U for details. During the Late Middle Ages, two minuscule glyphs of U developed which were both used for sounds including and modern . The pointed form "v" was written at the beginning of a word, while a rounded form "u" was used in the middle or end, regardless of sound. So whereas "valour" and "excuse" appeared as in modern printing, "have" and "upon" were printed as "haue" and "vpon". The first distinction between the letters "u" and "v" is recorded in a Gothic script from 1386, where "v" preceded "u". By the mid-16th century, the "v" form was used to represent the consonant and "u" the vowel sound, giving us the modern letter V. ...

Astronomical Society Of Edinburgh
The Astronomical Society of Edinburgh (ASE) is an association of amateur astronomers and other individuals interested in astronomy, which is based in Edinburgh, Scotland. The objectives are to encourage astronomical study and observation and to increase popular interest in astronomy. History The ASE was founded in 1924 as the Edinburgh Astronomical Association; it changed its name in 1937. The founding president was John McDougal Field, who was also deputy to the City Astronomer William Peck at the City Observatory on Calton Hill. At that time, the honorary presidents were Peck and the Astronomer Royal for Scotland, Ralph Allan Sampson. Field continued to run the City Observatory after Peck's death in 1925. The painter John Henry Lorimer was a member and vice president from 1930 to 1933. Upon his death in 1936, the ASE inherited the bulk of his estate. The ASE created the Lorimer Medal, connected to a series of high-profile public lectures. Field died in 1937, which led to ...

Flare Star
A flare star is a variable star that can undergo unpredictable dramatic increases in brightness for a few minutes. It is believed that the flares on flare stars are analogous to solar flares in that they are due to the magnetic energy stored in the stars' atmospheres. The brightness increase is across the spectrum, from X-rays to radio waves. The first known flare stars ( V1396 Cygni and AT Microscopii) were discovered in 1924. However, the best-known flare star is UV Ceti, first observed to flare in 1948. Today similar flare stars are classified as UV Ceti type variable stars (using the abbreviation UV) in variable star catalogs such as the General Catalogue of Variable Stars. Most flare stars are dim red dwarfs, although recent research indicates that less massive brown dwarfs might also be capable of flaring. The more massive RS Canum Venaticorum variables (RS CVn) are also known to flare, but it is understood that these flares are induced by a companion star in a binary system ...

Cygnus (constellation)
Cygnus is a northern constellation on the plane of the Milky Way, deriving its name from the Latinized Greek word for swan. Cygnus is one of the most recognizable constellations of the northern summer and autumn, and it features a prominent asterism known as the Northern Cross (in contrast to the Southern Cross). Cygnus was among the 48 constellations listed by the 2nd century astronomer Ptolemy, and it remains one of the 88 modern constellations. Cygnus contains Deneb (ذنب, translit. ''ḏanab,'' tail)one of the brightest stars in the night sky and the most distant first-magnitude staras its "tail star" and one corner of the Summer Triangle. It also has some notable X-ray sources and the giant stellar association of Cygnus OB2. Cygnus is also known as the Northern Cross. One of the stars of this association, NML Cygni, is one of the largest stars currently known. The constellation is also home to Cygnus X-1, a distant X-ray binary containing a supergiant and unseen m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jackson-Gwilt Medal
The Jackson-Gwilt Medal is an award that has been issued by the Royal Astronomical Society (RAS) since 1897. The original criteria were for the invention, improvement, or development of astronomical instrumentation or techniques; for achievement in observational astronomy; or for achievement in research into the history of astronomy. From 2017 onwards, the history of astronomy category has been removed and transferred to a new award, the Agnes Mary Clerke Medal. The frequency of the medal has varied over time. Initially it was irregular, with gaps of between three and five years between awards. From 1968 onwards it was awarded regularly every three years; from 2004 every two years; and since 2008 it has been awarded every year. The award is named after Hannah Jackson ''née'' Gwilt. She was a niece of Joseph Gwilt (an architect and Fellow of the RAS) and daughter of George Gwilt (another Fellow); Hannah donated the original funds for the medal. It is the second oldest award is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Society Of Edinburgh
The Royal Society of Edinburgh is Scotland's national academy of science and letters. It is a registered charity that operates on a wholly independent and non-partisan basis and provides public benefit throughout Scotland. It was established in 1783. , there are around 1,800 Fellows.

Henri Chrétien
Henri Jacques Chrétien (1 February 1879, Paris – 6 February 1956, Washington, D.C.) was a French astronomer and an inventor. Born in Paris, France, his most famous inventions are: - the anamorphic widescreen process, using an anamorphic lens system called Hypergonar, that resulted in the CinemaScope widescreen technique, and - the co-invention, with George Willis Ritchey, of the Ritchey–Chrétien telescope, an improved type of astronomical telescope, employing a system now used in virtually all large research telescopes. He spent part of his early astronomical career at the Nice Observatory, which was close to his house, the Villa Paradou. The Villa was built by famous French architect Charles Garnier who also built the Opera of Paris. In 1995, the abandoned villa was acquired by the artist Rainer Maria Latzke, who restored it and added new murals to the existing frescoes. Chrétien was one of the founders of the ''Institut d'optique théorique et appliquée'' and pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
