59 Elpis
Elpis, minor planet designation: 59 Elpis, is a large main belt asteroid that orbits the Sun with a period of 4.47 years. It is a C-type asteroid, meaning that it is very dark and carbonaceous in composition. In the Tholen scheme it has a classification of CP, while Bus and Binzen class it as type B. Elpis was discovered by Jean Chacornac from Paris, on September 12, 1860. It was Chacornac's sixth and final asteroid discovery. A controversy arose over the naming of Elpis. Urbain Le Verrier, director of the Paris Observatory, at first refused to allow Chacornac to name the object, because Leverrier was promoting a plan to reorganize asteroid nomenclature by naming them after their discoverers, rather than mythological figures. A protest arose among astronomers. At the Vienna Observatory, Edmund Weiss, who had been studying the asteroid, asked the observatory's director, Karl L. Littrow, to name it. Littrow chose Elpis, a Greek personification of hope, in reference to th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jean Chacornac
Jean Chacornac (21 June 1823 – 23 September 1873) was a French astronomer and discoverer of a comet and several asteroids. He was born in Lyon and died in Saint-Jean-en-Royans, southeastern France. Working in Marseille and Paris, he discovered six asteroids in the asteroid belt ''(see table)'' and C/1852 K1 (Chacornac), a parabolic comet in 1852. This comet is thought to be the source of the current Eta Eridanids meteors. He also independently discovered 20 Massalia, which discovery is credited to the Italian astronomer Annibale de Gasparis, however. Jean Chacornac was awarded the Lalande Prize in 1855, 1856 and in 1863. The asteroid 1622 Chacornac and the lunar crater '' Chacornac'' are named in his honour. References External links J.

Urbain Le Verrier
Urbain Jean Joseph Le Verrier FRS (FOR) HFRSE (; 11 March 1811 – 23 September 1877) was a French astronomer and mathematician who specialized in celestial mechanics and is best known for predicting the existence and position of Neptune using only mathematics. The calculations were made to explain discrepancies with Uranus's orbit and the laws of Kepler and Newton. Le Verrier sent the coordinates to Johann Gottfried Galle in Berlin, asking him to verify. Galle found Neptune in the same night he received Le Verrier's letter, within 1° of the predicted position. The discovery of Neptune is widely regarded as a dramatic validation of celestial mechanics, and is one of the most remarkable moments of 19th-century science. Biography Early years Le Verrier was born at Saint-Lô, Manche, France, in a modest bourgeois family, his parents being, Louis-Baptiste Le Verrier and Marie-Jeanne-Josephine-Pauline de Baudre. He studied at École Polytechnique. He briefly studied chemistry und ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Radar Astronomy
Radar astronomy is a technique of observing nearby astronomical objects by reflecting radio waves or microwaves off target objects and analyzing their reflections. Radar astronomy differs from ''radio astronomy'' in that the latter is a passive observation (i.e., receiving only) and the former an active one (transmitting and receiving). Radar systems have been conducted for six decades applied to a wide range of Solar System studies. The radar transmission may either be pulsed or continuous. The strength of the radar return signal is proportional to the inverse fourth-power of the distance. Upgraded facilities, increased transceiver power, and improved apparatus have increased observational opportunities. Radar techniques provide information unavailable by other means, such as testing general relativity by observing Mercury and providing a refined value for the astronomical unit. Radar images provide information about the shapes and surface properties of solid bodies, which ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Russell Hind
John Russell Hind FRS FRSE LLD (12 May 1823 – 23 December 1895) was an English astronomer. Life and work John Russell Hind was born in 1823 in Nottingham, the son of lace manufacturer John Hind and Elizabeth Russell, and was educated at Nottingham High School. At age 17 he went to London to serve an apprenticeship as a civil engineer, but through the help of Charles Wheatstone he left engineering to accept a position at the Royal Observatory, Greenwich under George Biddell Airy. Hind remained there from 1840 to 1844, at which time he succeeded W. R. Dawes as director of the private George Bishop's Observatory. In 1853 Hind became Superintendent of the Nautical Almanac, a position he held until 1891. Hind is notable for being one of the early discoverers of asteroids. He also discovered and observed the variable stars R Leporis (also known as Hind's Crimson Star), U Geminorum, and T Tauri (also called Hind's Variable Nebula), and discovered the variability of μ Cephei. ...

Hope
Hope is an optimistic state of mind that is based on an expectation of positive outcomes with respect to events and circumstances in one's life or the world at large. As a verb, its definitions include: "expect with confidence" and "to cherish a desire with anticipation." Among its opposites are dejection, hopelessness, and despair. In psychology Professor of Psychology Barbara Fredrickson argues that hope comes into its own when crisis looms, opening us to new creative possibilities. Frederickson argues that with great need comes an unusually wide range of ideas, as well as such positive emotions as happiness and joy, courage, and empowerment, drawn from four different areas of one's self: from a cognitive, psychological, social, or physical perspective. Hopeful people are "like the little engine that could, ecausethey keep telling themselves "I think I can, I think I can". Such positive thinking bears fruit when based on a realistic sense of optimism, not on a naive "f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
