Search for Sirius companions
Many direct or indirect observations have suggested the existence of a second companion (in addition of the white dwarf Sirius-B) around the brilliant star Sirius-A. The presence of a second faint star could in particular explain a change of color of Sirius, as suggested by historical texts. A team... view more (2000-11-24)

Scientists find black hole's 'point of no return'
Scientists have found new evidence that black holes are performing the disappearing acts for which they are known.   view more (2006-01-11)

Space is dusty, and now astronomers know why
Massive star supernovae have been major "dust factories" ever since the first generations of stars formed several hundred million years after the Big Bang, according to an international study published in Science Express today.   view more (2006-06-09)

Hubble finds mysterious disk of blue stars around a black hole
Astronomers using the NASA/ESA Hubble Space Telescope have identified the source of a mysterious blue light surrounding a supermassive black hole in our neighbouring Andromeda Galaxy (M31).   view more (2005-09-21)

New insight in star formation
Early stages of star formation are now better understood, following an extensive millimeter-wave study of protostars, which are young stellar objects still deeply embedded in their parent molecular cloud. Thanks to their unprecedented high-resolution maps of the circumstellar environment of many... view more (2001-01-16)

It`s wet out there
TANTALISING signs of water have been found in the atmospheres of planets orbiting distant stars. If the discovery is confirmed, it will fuel speculation that the Galaxy is teeming with life. "This would be a historic discovery- the first detection of a prebiotic molecule in an extrasolar planet,"... view more (2002-09-20)

NASA predicts nongreen plants on other planets
NASA scientists believe they have found a way to predict the color of plants on planets in other solar systems.   view more (2007-04-11)

Dust-enshrouded star looks similar to our sun
Astronomers report tremendous quantities of warm dusty debris surrounding a star with luminosity and mass similar to the sun's, but located 300 light-years from Earth.   view more (2005-07-21)

ESA Looks Further Back In Time
Europe's X- ray Multi Mirror (XMM) space telescope goes on show for the first time on Tuesday 10 February 1998. When it is launched in 1999 into an orbit 70,000 miles above the earth, XMM will search for cosmic x-rays from the intensely hot areas of our galaxy and beyond. Sources of these x-rays... view more (1998-02-09)

Ten Inventions Created for James Webb Space Telescope Approved
Scientists and engineers have been working for years to develop ten technologies for NASA's James Webb Space Telescope, like big mirrors that will actually move around in space and computer software that will make it happen, or the materials that make up a giant sunshield as big as a tennis court.   view more (2007-05-04)

Magnetism shapes beauty in the heavens
Using a technique based on the work of the 1902 Nobel Prizewinner, Pieter Zeeman, an international team of astronomers have, for the first time, provided conclusive proof that the magnetic field close to a number of aging stars is 10 to 100 times stronger than that of our own Sun. These... view more (2002-11-01)

Astronomers Expect To Be "Dazled" By Views Of Ancient Universe
ROYAL ASTRONOMICAL SOCIETY PRESS NOTICE: ASTRONOMERS EXPECT TO BE "DAZLED" BY VIEWS OF ANCIENT UNIVERSE   view more (2005-04-05)

Ice has a starring role - CMD19/CMMP with The Physics Congress 2002
When even moderately hot stars like our Sun have surface temperatures of around 6,000°C, it is hard to imagine that ice plays an important part in their formation. But that`s exactly what astrophysicists have recently discovered by turning to surface scientists for help. At the Condensed Matter... view more (2002-03-26)

Two new dusty planetary disks may be astrophysical mirrors of our Kuiper Belt
A survey by NASA's Hubble Space Telescope of 22 nearby stars has turned up two with bright debris disks that appear to be the equivalent of our own solar system's Kuiper Belt, a ring of icy rocks outside the orbit of Neptune and the source of short-period comets.   view more (2006-01-20)

Circumstellar space: Where chemistry happens for the very first time
Picture a cool place, teeming with a multitude of hot bodies twirling about in rapidly changing formations of singles and couples, partners and groups, constantly dissolving and reforming.   view more (2007-08-01)

Astronomers report mysterious giant star clusters
An international team of astronomers reported evidence for the formation of mysterious "super star clusters" Jan. 9 at the annual meeting of the American Astronomical Society in Washington, D.C.   view more (2006-01-11)

Stellar forensics with striking new image from Chandra
A spectacular new image shows how complex a star's afterlife can be. By studying the details of this image made from a long observation by NASA's Chandra X-ray Observatory, astronomers can better understand how some stars die and disperse elements like oxygen into the next generation of stars and... view more (2007-10-24)

Pulsar find boosts hope for gravity-wave hunters
Neutron star pairs may merge and give off a burst of gravity waves about six times more often than previously thought, scientists report in today's issue of the journal Nature [4 December]. If so, the current generation of gravity-wave detectors might be able to register such an event every year or... view more (2003-12-02)

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)

The Drifting Star
By studying in great detail the 'ringing' of a planet-harbouring star, a team of astronomers using ESO's 3.6-m telescope have shown that it must have drifted away from the metal-rich Hyades cluster. This discovery has implications for theories of star and planet formation, and for the dynamics of... view more (2008-04-16)

Ideas on gas-giant planet formation take shape
Rocky planets such as Earth and Mars are born when small particles smash together to form larger, planet-sized clusters in a planet-forming disk, but researchers are less sure about how gas-giant planets such as Jupiter and Saturn form.   view more (2006-03-23)

Star Family Seen Through Dusty Fog
Images made with ESO's New Technology Telescope at La Silla by a team of German astronomers reveal a rich circular cluster of stars in the inner parts of our Galaxy. Located 30,000 light-years away, this previously unknown closely-packed group of about 100,000 stars is most likely a new globular... view more (2007-03-14)

Unusual meteorite unlocks treasure trove of solar system secrets
An unusual meteorite that fell on a frozen lake in Canada five years ago has led a Florida State University geochemist to a breakthrough in understanding the origin of the chemical elements that make up our solar system.   view more (2005-09-28)

Astronomers use laser to take clearest images of the center of the Milky Way
UCLA astronomers and colleagues have taken the first clear picture of the center of our Milky Way galaxy, including the area surrounding the supermassive black hole, using a new laser virtual star at the W.M. Keck observatory in Hawaii.   view more (2005-12-21)

In Unique Stellar Laboratory, Einstein's Theory Passes Strict, New Test
Taking advantage of a unique cosmic configuration, astronomers have measured an effect predicted by Albert Einstein's theory of General Relativity in the extremely strong gravity of a pair of superdense neutron stars. Essentially, the famed physicist's 93-year-old theory passed yet another test.   view more (2008-07-07)
