Olin Eggen
Olin Jeuck Eggen (July 9, 1919 – October 2, 1998) was an American astronomer. Biography Olin Jeuck Eggen was born to Olin Eggen and Bertha Clare Jeuck in the village of Orfordville in Rock County, Wisconsin. Both of his parents were of Norwegian extraction. He graduated from the University of Wisconsin–Madison in 1940. After serving in World War II in the OSS, he returned to the university and received his Ph.D. in astrophysics in 1948. He became known as one of the best observational astronomers of his time. He is best known for a seminal 1962 paper with Donald Lynden-Bell and Allan Sandage which suggested for the first time that the Milky Way Galaxy had collapsed out of a gas cloud. He pioneered the now-accepted notion of moving groups, and introduced the idea that these may originate from dissolved open clusters. He won the Henry Norris Russell Lectureship in 1985. Over that time he held positions at Lick Observatory (1948–1956), Royal Greenwich Observatory (1956 ...

Henry Norris Russell Lectureship
The Henry Norris Russell Lectureship is awarded each year by the American Astronomical Society in recognition of a lifetime of excellence in astronomical research. The idea for the lectureship came from then society President Harlow Shapley in 1945, who led the fund raising drive to collect $10,000 from the membership. One of the major contributors was the Mexican Ambassador to the United States, as Russell had been an important representative at the dedication ceremony for the Mexican National Observatory. The goal was reached in December 1946, using not a little amount of coercive language by Shapley. The first Russell lecturer was, naturally, fellow American astronomer Henry Norris Russell, for whom the award is named. Russell gave a lecture titled "The Royal Road of Eclipses" concerning eclipsing binary stars. Previous lecturers This list of lecturers is from the American Astronomical Society's website.

Nicholas B
Nicholas is a male given name and a surname. The Eastern Orthodox Church, the Roman Catholic Church, and the Anglican Churches celebrate Saint Nicholas every year on December 6, which is the name day for "Nicholas". In Greece, the name and its derivatives are especially popular in maritime regions, as St. Nicholas is considered the protector saint of seafarers. Origins The name is derived from the Greek name Νικόλαος (''Nikolaos''), understood to mean 'victory of the people', being a compound of νίκη ''nikē'' 'victory' and λαός ''laos'' 'people'.. An ancient paretymology of the latter is that originates from λᾶς ''las'' ( contracted form of λᾶας ''laas'') meaning 'stone' or 'rock', as in Greek mythology, Deucalion and Pyrrha recreated the people after they had vanished in a catastrophic deluge, by throwing stones behind their shoulders while they kept marching on. The name became popular through Saint Nicholas, Bishop of Myra in Lycia, the inspir ...

Neptune
Neptune is the eighth planet from the Sun and the farthest known planet in the Solar System. It is the fourth-largest planet in the Solar System by diameter, the third-most-massive planet, and the densest giant planet. It is 17 times the mass of Earth, and slightly more massive than its near-twin Uranus. Neptune is denser and physically smaller than Uranus because its greater mass causes more gravitational compression of its atmosphere. It is referred to as one of the solar system's two ice giant planets (the other one being Uranus). Being composed primarily of gases and liquids, it has no well-defined "solid surface". The planet orbits the Sun once every 164.8 julian year (astronomy), years at an average distance of . It is named after the Neptune (mythology), Roman god of the sea and has the astronomical symbol , representing Neptune's trident. Neptune is not visible to the unaided eye and is the only planet in the Solar System found by mathematical prediction ...

Astronomical Society Of Australia
The Astronomical Society of Australia (ASA) is the professional body representing astronomers in Australia. Established in 1966, it is incorporated in the Australian Capital Territory. Membership of the ASA is open to people "capable of contributing to the advancement of astronomy or a closely related field". This means that the members are mainly active professional astronomers and postgraduate students. Some retired astronomers and distinguished amateur astronomers are also members, and several organisations are corporate members of the society. The ASA currently has around 600 members. It publishes a peer-reviewed journal, ''Publications of the Astronomical Society of Australia''. History At its establishment in 1966, notable astronomer Ben Gascoigne was its first vice-president. Activities The society currently has four topical interest groups: * the Australian National Institute for Theoretical Astrophysics (ANITA), a virtual institute which aims to raise the profile of Aust ...

American Astronomical Society
The American Astronomical Society (AAS, sometimes spoken as "double-A-S") is an American society of professional astronomers and other interested individuals, headquartered in Washington, DC. The primary objective of the AAS is to promote the advancement of astronomy and closely related branches of science, while the secondary purpose includes enhancing astronomy education and providing a political voice for its members through lobbying and grassroots activities. Its current mission is to enhance and share humanity's scientific understanding of the universe as a diverse and inclusive astronomical community. History The society was founded in 1899 through the efforts of George Ellery Hale. The constitution of the group was written by Hale, George Comstock, Edward Morley, Simon Newcomb and Edward Charles Pickering. These men, plus four others, were the first Executive Council of the society; Newcomb was the first president. The initial membership was 114. The AAS name of the so ...

Cerro Tololo Inter-American Observatory
The Cerro Tololo Inter-American Observatory (CTIO) is an astronomical observatory located on Cerro Tololo in the Coquimbo Region of northern Chile, with additional facilities located on Cerro Pachón about to the southeast. It is approximately east of La Serena, where support facilities are located. The site was identified by a team of scientists from Chile and the United States in 1959, and it was selected in 1962. Construction began in 1963 and regular astronomical observations commenced in 1965. Construction of large buildings on Cerro Tololo ended with the completion of the Víctor Blanco Telescope in 1974, but smaller facilities have been built since then. Cerro Pachón is still under development, with two large telescopes (Gemini South and SOAR) inaugurated since 2000, and one in the early stages of construction (the Vera C. Rubin Observatory) The principal telescopes at CTIO are the 4 m Víctor M. Blanco Telescope, named after Puerto Rican astronomer Víctor Manuel ...

Mount Stromlo Observatory
Mount Stromlo Observatory located just outside Canberra, Australia, is part of the Research School of Astronomy and Astrophysics at the Australian National University (ANU). History The observatory was established in 1924 as The Commonwealth Solar Observatory. The Mount Stromlo site had already been used for observations in the previous decade, a small observatory being established there by Pietro Baracchi using the Oddie telescope located there in 1911. The dome built to house the Oddie telescope was the first Commonwealth building constructed in the newly established Australian Capital Territory. In 1911 a delegation for an Australian Solar Observatory went to London seeking Commonwealth assistance. The League of the Empire sought subscriptions to assist raising funds. Survey work to determine the site's suitability had begun as soon as the idea of a new Capital was established. By 1909 the Australian Association for the Advancement of Science was assisted in this effort ...
