Astronomers Weigh the Coldest Brown Dwarfs with Astronomy's Sharpest Eyes
Astronomers have used ultrasharp images obtained with the Keck Telescope and Hubble Space Telescope to determine for the first time the masses of the coldest class of "failed stars," a.k.a. brown dwarfs.   view more (2008-06-03)

Old Galaxies in the Young Universe
Very Large Telescope Unravels New Population of Very Old Massive Galaxies [1] Current theories of the formation of galaxies are based on the hierarchical merging of smaller entities into larger and larger structures, starting from about the size of a stellar globular cluster and ending with... view more (2004-07-06)

Voracious black holes hide their appetite in dusty galaxies
A UK-led team of astronomers reports that they have tracked down an elusive population of black holes growing rapidly hidden behind clouds of dust.   view more (2005-08-08)

New deep space images of distant strip of sky to be available on Google
A global project to map a distant strip of the universe is releasing its data today to scientists and the public to be used as part of Google Sky, a new feature of Google Earth.   view more (2007-10-04)

Astronomers report unprecedented double helix nebula near center of the Milky Way
Astronomers report an unprecedented elongated double helix nebula near the center of our Milky Way galaxy, using observations from NASA's Spitzer Space Telescope.   view more (2006-03-16)

How do massive stars form?
Massive stars play a key role in the chemical and dynamical evolution of galaxies. The way massive stars form is still much debated among the astronomers' community: it is currently one of the hottest astrophysical topics.   view more (2005-11-09)

Possible closest neutron star to Earth found
Using NASA's Swift satellite, McGill University and Penn State University astronomers have identified an object that is likely one of the closest neutron stars to Earth -- and possibly the closest.   view more (2007-08-21)

Mapping the Milky Way
A new map of the centre of our own galaxy, The Milky Way, is the biggest, most detailed, and most sensitive yet made. The map shows giant streamers and huge clouds of interstellar gas where stars are being born 26,000 light years from Earth - shedding new light on the exotic structures in this... view more (2000-12-19)

Hubble finds that "blue blobs" in space are orphaned clusters of stars
Hubble has revealed that mysterious "blue blobs" in a structure called Arp's Loop between M81 and M82 are blue clusters of stars less than 200 million years old with many stars as young as, and even younger than, 10 million years.   view more (2008-01-09)

Lots of Small Stars Born in Starburst Region
The present research programme was granted observing time with VLT ANTU in April 1999. Its general aim is to investigate collective, massive star formation, in particular the coalescence of high- and low-mass stars in the violent environments of starburst regions. These are areas in which the... view more (1999-10-13)

Old idea spawns new way to study dark matter
An international team of astronomers led by Ohio State University has examined dark matter in the outer reaches of our galaxy in a new way. For the first time, they were able to employ triangulation -- a method rooted in ancient Greek geometry -- to estimate the location of dark matter and... view more (2007-05-31)

Astronomers discover new kind of black-hole explosion
Scientists have discovered what appears to be a new kind of cosmic explosion - a "hybrid gamma-ray burst" - which will be the subject of four articles to be published in the journal Nature on 21 December 2006.   view more (2006-12-21)

The Purple Rose of Virgo
ntil now NGC 5584 was just one galaxy among many others, located to the West of the Virgo Cluster. Known only as a number in galaxy surveys, its sheer beauty is now revealed in all its glory in a new VLT image. Since 1 March, this purple cosmic rose also holds the brightest stellar explosion of the... view more (2007-03-28)

Extreme Winds Rule Exoplanet's Weather
Supersonic winds more than six times faster than those on Jupiter are blasting through the atmosphere of a Jupiter-sized planet 60 light years away, say scientists who've analyzed results from NASA's Spitzer Space Telescope.   view more (2007-05-10)

Dutch Minister of Science Visits ESO Facilities in Chile
Mrs. Maria van der Hoeven, the Dutch Minister of Education, Culture and Science, who travelled to the Republic of Chile, arrived at the ESO Paranal Observatory on Friday afternoon, May 13, 2005.   view more (2005-05-17)

German Foreign Minister Visits Paranal Observatory
During his current tour of countries in South America, the Honourable Foreign Minister of Germany, Mr. Joschka Fischer, stopped over at the ESO Paranal Observatory Wednesday night (March 6 - 7, 2002). Arriving in Antofagasta, capital of the II Chilean region, the Foreign Minister and his suite was... view more (2002-03-07)

Amateurs and professionals combine observations to produce detailed picture of double asteroid
Roping together observations from the world's largest telescopes as well as the small instrument of a local backyard amateur, astronomers have assembled the most complete picture yet of a pair of asteroids whirling around one another in a perpetual pas de deux.   view more (2007-03-30)

AEGIS survey reveals new principle governing galaxy formation and evolution
Faced with the bewildering array of galaxies in the universe, from orderly spirals to chaotic mergers, it is hard to imagine a unifying principle that describes them all with mathematical precision. But that is just what astronomers have now discovered.   view more (2007-03-07)

Quasars help trace ancestors of giant elliptical galaxies
By using the Hubble Space Telescope (HST) as a `time machine`, astronomers from the Universities of Edinburgh and Oxford in the UK and the Space Telescope Science Institute (STScI) in Baltimore in the USA have been able to trace back the history of massive elliptical galaxies. They have found that... view more (2002-04-04)

Optical vortex could look directly at extrasolar planets
A new optical device might allow astronomers to view extrasolar planets directly without the annoying glare of the parent star.   view more (2005-12-01)

Scientists weigh ingredients in recipe of the Universe
An international team of scientists from Cambridge, Manchester and Tenerife has released the first results of new high-precision observations of the relic radiation from the Big Bang, often called the cosmic microwave background or CMB. These observations have been made with a novel radio telescope... view more (2002-05-23)

New evidence for dark energy in the universe
An international team of astronomers, led by scientists at the University of Manchester have produced new evidence that most of the energy in the Universe is in the form of the mysterious "Dark Energy". The new evidence comes from a 10-year census of the sky for examples of gravitational lenses,... view more (2002-11-09)

Gas giants jump into planet formation early
Observations from NASA's Spitzer Space Telescope show that gas giants either form within the first 10 million years of a sun-like star's life, or not at all.   view more (2007-01-09)

A Warm South Pole? Yes, on Neptune!
An international team of astronomers using ESO's Very Large Telescope has discovered that the south pole of Neptune is much hotter than the rest of the planet. This is consistent with the fact that it is late southern summer and this region has been in sunlight for about 40 years.   view more (2007-09-19)

Galaxies of stars shrouded in dust found in the early universe
A team of astronomers based in the UK and the US has for the first time measured the redshifts of a significant sample of puzzling "submillimetre galaxies", discovered by some members of the team in 1997. Dr Ian Smail of the University of Durham will tell the UK/Ireland National Astronomy Meeting... view more (2003-03-31)
