Latest European Southern Observatory Stories
Scientists using the Atacama Large Millimeter/submillimeter Array in Chile have observed a very exciting phenomenon — the exchange of dust and gas in a multiple-star system.
Observations of the expanding thermonuclear fireball from a nova that erupted last year have resulted in the first ever images of an exploding star during this stage and revealed how the ejected material’s structure evolves as the gas cools and expands.
Scientists at the Universities of Bonn and Cardiff see good times approaching for astrophysicists after hatching a new observational strategy to distill detailed information from galaxies at the edge of the Universe.
Galaxy clusters are the largest objects in the Universe held together by gravity but their formation is not well understood.
The Wide Field Imager on the MPG/ESO 2.2-meter telescope at ESO’s La Silla Observatory in Chile has taken this beautiful image, dappled with blue stars, of one of the most star-rich open clusters currently known — Messier 11, also known as NGC 6705 or the Wild Duck Cluster.
Out of every four proposals submitted to gain observation time on the Hubble Space Telescope, three are denied. You might think that these denials are based strictly on the merits of the study being proposed and the current viewing patterns of the telescope, but you would be wrong.
Astronomers have discovered a supermassive black hole in the ultracompact dwarf galaxy M60-UCD1, making it the smallest galaxy ever found to host one of these enormous light-sucking objects.
Spotting Earth-threatening asteroids is tough partly because the sky is so big. But insects offer an answer, since they figured out long ago how to look in many directions at once.
VLT observations of Messier 54 show the lithium problem also applies outside our galaxy.
Lupus 4, a spider-shaped blob of gas and dust, blots out background stars like a dark cloud on a moonless night in this intriguing new image. Although gloomy for now, dense pockets of material within clouds such as Lupus 4 are where new stars form and where they will later burst into radiant life.
Very Large Telescope -- The Very Large Telescope (VLT) consist of four optical telescopes that have 8.4 meter aperture. The VLT is a project of the European Southern Observatory organization. It is located at the Paranal Observatory on Cerro Paranal, a 2,635-m high mountain in the Atacama desert in northern Chile. The VLT consists of a cluster four of large telescopes, and an interferometer (VLTI) which will be used to resolve fine features. The telescopes have been named after the...
Overwhelmingly Large Telescope -- The European Southern Observatory has undertaken a concept study for the next generation of ground-based Extremely Large Telescopes (ELTs). Dubbed OWL, ESO's concept is conceived as a 100 m. diameter optical and near-infrared, adaptive telescope. With milliarc second resolution and limiting magnitude V~38, OWL will be capable of imaging solar system objects at resolutions comparable to that offered by space probes, over much longer time scales. It...
La Silla Observatory -- La Silla is a 2400-m mountain, bordering the southern extremity of the Atacama desert in Chile. It is located about 160 Km north of La Serena. Its geographical coordinates are: Latitude 29 15' south & Longitude 70 44' west. Originally known as Cinchado, the mountain was renamed La Silla (the saddle) after its shape. It rises quite isolated and remote from any artificial light and dust sources (astronomy's worst enemies). La Silla was the first ESO...
European Southern Observatory -- ESO, the European Southern Observatory, was created in 1962 to: "establish and operate an astronomical observatory in the southern hemisphere, equipped with powerful instruments, with the aim of furthering and organising collaboration in astronomy". ESO is supported by Belgium, Denmark, France, Germany, Italy, the Netherlands, Portugal, Sweden, Switzerland and United Kingdom. Other countries have expressed interest to become a member as well. ESO...
Mount Wilson Observatory -- astronomical observatory located in California on Mt. Wilson, near Pasadena. Mt. Wilson Observatory was founded in 1904 by George E. Hale. Its equipment includes 100-in. (2.5-m) and 60-in. (1.50-m) reflecting telescopes and two solar-tower telescopes 150 ft. (46 m) and 60 ft. (18 m) in length. The most recent addition is the CHARA (Center for High Angular Resolution Astronomy) array operated by Georgia State Univ.; it consists of six 39-in. (1-m) aperture...
