Louis Thollon
Louis Thollon (2 May 1829 – 8 April 1887) was a French astronomer. He was born in Ambronay, France. Beginning in 1881, Thollon joined the staff of the new Nice Observatory where he undertook a long-term observation program of the Sun using a spectroscope of his own design. In the process, he recorded a solar spectrum consisting of 3,000 absorption lines in the optical band. In 1882, he joined André Puiseux on an expedition to Egypt to observe the solar eclipse on 17 May. The same year he traveled to Portugal to watch the Venus transit, but was met with disappointment due to poor weather. He was awarded the Prix Lalande in 1885 for his large map of the Solar System, which was not published until after his death in 1890.Hentschel K. (2007) Thollon, Louis. In: Hockey T. et al.

Solar System
The Solar SystemCapitalization of the name varies. The International Astronomical Union, the authoritative body regarding astronomical nomenclature, specifies capitalizing the names of all individual astronomical objects but uses mixed "Solar System" and "solar system" structures in theinaming guidelines document. The name is commonly rendered in lower case ('solar system'), as, for example, in the ''Oxford English Dictionary'' an''Merriam-Webster's 11th Collegiate Dictionary''. is the gravitationally bound Planetary system, system of the Sun and the objects that orbit it. It Formation and evolution of the Solar System, formed about 4.6 billion years ago when a dense region of a molecular cloud collapsed, forming the Sun and a protoplanetary disc. The Sun is a typical star that maintains a hydrostatic equilibrium, balanced equilibrium by the thermonuclear fusion, fusion of hydrogen into helium at its stellar core, core, releasing this energy from its outer photosphere.

Giovanni Schiaparelli
Giovanni Virginio Schiaparelli ( , , ; 14 March 1835 – 4 July 1910) was an Italian astronomer and science historian. Biography He studied at the University of Turin, graduating in 1854, and later did research at Berlin Observatory, under Encke. In 1859–1860 he worked in Pulkovo Observatory near St Petersburg, and then worked for over forty years at Brera Observatory in Milan. He was also a senator of the Kingdom of Italy, a member of the Accademia dei Lincei, the Accademia delle Scienze di Torino and the Regio Istituto Lombardo, and is particularly known for his studies of Mars. Mars Among Schiaparelli's contributions are his telescopic observations of Mars. In his initial observations, he named the " seas" and "continents" of Mars. During the planet's "great opposition" of 1877, he observed a dense network of linear structures on the surface of Mars, which he called in Italian, meaning "channels", but the term was mistranslated into English as "canals".Washam ...

Martian Canals
During the late 19th and early 20th centuries, it was erroneously believed that there were "canals" on the planet Mars. These were a network of long straight lines in the equatorial regions from 60° north to 60° south latitude on Mars, observed by astronomers using early telescopes without photography. They were first described by the Italian astronomer Giovanni Schiaparelli during the opposition of 1877, and attested to by later observers. Schiaparelli called these ''canali'' (" channels"), which was mis-translated into English as "canals". The Irish astronomer Charles E. Burton made some of the earliest drawings of straight-line features on Mars, although his drawings did not match Schiaparelli's. Around the turn of the century there was even speculation that they were engineering works, irrigation canals constructed by a civilization of intelligent aliens indigenous to Mars. By the early 20th century, improved astronomical observations revealed that, with the possible ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Henri Joseph Anastase Perrotin
Henri Joseph Anastase Perrotin (December 19, 1845 – February 29, 1904) was a French astronomer and a discoverer of minor planets. Some sources give his middle name as Athanase. In his early career, he and Guillaume Bigourdan were assistants of Félix Tisserand at Toulouse Observatory. Later, he was the first director of the Nice Observatory in Nice, France from 1884 until his death. He made observations of Mars and attempted to determine the rotation period of Venus. He also calculated perturbations in the orbit of 4 Vesta. In the literature, he is sometimes referred to as Henri Perrotin and sometimes as Joseph Perrotin (this is indeed one and the same person). He is also referenced in H. G. Wells's novel ''The War of the Worlds'' as "Perrotin of Nice". His 6 asteroid discoveries are credited by the Minor Planet Center to "J. Perrotin". He won the Prix Lalande in 1875 and 1883. The Martian crater Perrotin and the inner main-belt asteroid 1515 Perrotin were named in ...

Opposition (planets)
In positional astronomy, two astronomical objects are said to be in opposition when they are on opposite sides of the celestial sphere, as observed from a given body (usually Earth). A planet (or asteroid or comet) is said to be "in opposition" or "at opposition" when it is in opposition to the Sun. Because most orbits in the Solar System are nearly coplanar to the ecliptic, this occurs when the Sun, Earth, and the body are configured in an approximately straight line, or syzygy; that is, Earth and the body are in the same direction as seen from the Sun. Opposition occurs only for superior planets (see the diagram). The instant of opposition is defined as that when the apparent geocentric celestial longitude of the body differs by 180° from the apparent geocentric longitude of the Sun. At that time, a body is: * in apparent retrograde motion * visible almost all night – rising around sunset, culminating around midnight, and setting around sunrise * at the point i ...

Lalande Prize
The Lalande Prize (French: ''Prix Lalande'' also known as Lalande Medal) was an award for scientific advances in astronomy, given from 1802 until 1970 by the French Academy of Sciences. The prize was endowed by astronomer Jérôme Lalande in 1801, a few years before his death in 1807, to enable the Academy of Sciences to make an annual award "to the person who makes the most unusual observation or writes the most useful paper to further the progress of Astronomy, in France or elsewhere." The awarded amount grew in time: in 1918 the amount awarded was 1000 Francs, and by 1950, it was 10,000 francs. It was combined with the Valz Prize ''(Prix Valz)'' in 1970 to create the Lalande-Valz Prize and then with a further 122 foundation prizes in 1997, resulting in the establishment of the Grande Médaille. The Grande Medaille is not limited to the field of astronomy. Winners See also * List of astronomy awards * List of Nobel laureates—Nobel Prize The Nobel Prizes ( ; ; ...
