A globular cluster is a spheroidal conglomeration of stars. Globular clusters are bound together by gravity, with a higher concentration of stars towards their centers. They can contain anywhere from tens of thousands to many millions of member stars. Their name is derived from Latin globulus. Globular clusters are occasionally known simply as "globulars".
Phoenix is a minor constellation in the southern sky. Named after the mythical phoenix, it was first depicted on a celestial atlas by Johann Bayer in his 1603 Uranometria. The French explorer and astronomer Nicolas Louis de Lacaille charted the brighter stars and gave their Bayer designations in 1756. The constellation stretches from roughly −39° to −57° declination, and from 23.5h to 2.5h of right ascension. The constellations Phoenix, Grus, Pavo and Tucana, are known as the Southern Birds.
The European Organisation for Astronomical Research in the Southern Hemisphere, commonly referred to as the European Southern Observatory (ESO), is an intergovernmental research organisation made up of 16 member states for ground-based astronomy. Created in 1962, ESO has provided astronomers with state-of-the-art research facilities and access to the southern sky. The organisation employs about 730 staff members and receives annual member state contributions of approximately €162 million. Its observatories are located in northern Chile.
An astronomical object, celestial object, stellar object or heavenly body is a naturally occurring physical entity, association, or structure that exists in the observable universe. In astronomy, the terms object and body are often used interchangeably. However, an astronomical body or celestial body is a single, tightly bound, contiguous entity, while an astronomical or celestial object is a complex, less cohesively bound structure, which may consist of multiple bodies or even other objects with substructures.
Eric Walter Elst was a Belgian astronomer at the Royal Observatory of Belgium in Uccle and a prolific discoverer of asteroids. The Minor Planet Center ranks him among the top 10 discoverers of minor planets with thousands of discoveries made at ESO's La Silla Observatory in northern Chile and at the Rozhen Observatory in Bulgaria during 1986–2009.
Robert George Harrington was an American astronomer who worked at Palomar Observatory. He should not be confused with Robert Sutton Harrington, who was also an astronomer, but was born later and worked at the US Naval Observatory.
Richard Martin West is a Danish astronomer and discoverer of astronomical objects with a long career at the European Southern Observatory (ESO) and at the International Astronomical Union (IAU).
The Uppsala–ESO Survey of Asteroids and Comets (UESAC) took place in 1992–1993. A large number of asteroids were investigated. Over 15,000 positions were detected, and orbits were calculated for 2500.
Milorad B. Protić was a Serbian astronomer, discoverer of comets and minor planets, and three times director of the Belgrade Observatory.
Hans Scholl is a German astronomer, who worked at the Astronomisches Rechen-Institut in Heidelberg, Germany, and at the Côte d'Azur Observatory in Nice, France. In 1999, he was part of a team that discovered three moons of Uranus: Prospero, Setebos and Stephano. He has also co-discoverered 55 minor planets together with Italian astronomer Andrea Boattini at ESO's La Silla Observatory site in northern Chile during 2003–2005.
The Uppsala–DLR Trojan Survey is an astronomical survey to study the movements and locations of asteroids near Jupiter, which includes Jupiter trojans and other asteroids, which line-of sight are frequently blocked by the giant planet.
La Silla Observatory is an astronomical observatory in Chile with three telescopes built and operated by the European Southern Observatory (ESO). Several other telescopes are located at the site and are partly maintained by ESO. The observatory is one of the largest in the Southern Hemisphere and was the first in Chile to be used by ESO.
The Phoenix Dwarf is a dwarf irregular galaxy discovered in 1976 by Hans-Emil Schuster and Richard Martin West and mistaken for a globular cluster. It is currently 1.44 Mly away from Earth. Its name comes from the fact that it is part of the Phoenix constellation.
9951 Tyrannosaurus, provisional designation 1990 VK5, is a stony Vestian asteroid from the inner regions of the asteroid belt, approximately 17 kilometers in diameter. It was discovered on 15 November 1990, by Belgian astronomer Eric Elst at ESO's La Silla Observatory in northern Chile. It was named after Tyrannosaurus, a genus of dinosaurs.
3268 De Sanctis, provisional designation 1981 DD, is a Vestian asteroid from the inner regions of the asteroid belt, approximately 6 kilometers in diameter. It was discovered on 26 February 1981, by European astronomers Henri Debehogne and Giovanni de Sanctis at ESO's La Silla Observatory in northern Chile. The asteroid was named after the second discoverer. The assumed S-type asteroid has a rotation period of 17 hours.
2187 La Silla, provisionally designated 1976 UH, is a stony Eunomia asteroid from the middle region of the asteroid belt, approximately 12 kilometers in diameter.
2590 Mourão is a bright Vesta asteroid from the inner regions of the asteroid belt, approximately 7 kilometers in diameter. It was discovered on 22 May 1980, by Belgian astronomer Henri Debehogne at ESO's La Silla Observatory in northern Chile. The V-type asteroid has a rotation period of 15.6 hours. It was named after Brazilian astronomer Ronaldo Rogério de Freitas Mourão.
The Transiting Planets and Planetesimals Small Telescope (TRAPPIST) is the corporate name for a pair of Belgian optic robotic telescopes. TRAPPIST–South, which is situated high in the Chilean mountains at ESO's La Silla Observatory, came online in 2010, and TRAPPIST–North situated at the Oukaïmeden Observatory in the Atlas Mountains in Morocco, came online in 2016.
Tenagra Observatory and Tenagra Observatory II are astronomical observatories in Cottage Grove, Oregon and Arizona. The observatories house heavily automated robotic telescopes.
