Nearby star much older than thought
Dec 11, 2012 (UPI)
The star Vega, used as a "yardstick" to gage other stars' brightness for thousands of years, may be much older than previously thought, U.S. astronomers say. Re...
Galaxy-wide echoes from the past
Dec 10, 2012 (SPX)
Many galaxies have a giant black hole at their centre that causes the gas around it to glow. However, in the case of green bean galaxies, the entire galaxy is g...
The Bubble Nebula, observed with the new One Degree Imager Camera
Dec 10, 2012 (SPX)
Just in time for the holidays, a spectacular image of the Bubble Nebula (NGC 7635) demonstrates the potential of the new camera known as the One Degree Imager, ...
Wide Binary Stars: Long-Distance Stellar Relationships
Dec 10, 2012 (SPX)
Using computer simulations, scientists from Hawaii and Finland have figured out how wide binary stars-two stars that orbit each other at a distance up to a ligh...
X-ray vision can reveal the moment of birth of violent supernovae
Dec 10, 2012 (SPX)
A team of astronomers led by the University of Leicester has uncovered new evidence that suggests that X-ray detectors in space could be the first to witness ne...
Secrets of universe revealed thanks to AF research complex
Dec 10, 2012 (SPX)
Looking skyward, scientists worldwide now know the universe's size, composition, approximate age and rate of expansion, thanks in part to "essential" data deriv...
Crowdsourcing the cosmos: Astronomers welcome all to identify star clusters in Andromeda galaxy
Dec 07, 2012 (SPX)
Astronomers are inviting the public to search Hubble Space Telescope images of the Andromeda galaxy to help identify star clusters and increase understanding of...
'Dark Core' May Not Be So Dark After All
Dec 06, 2012 (SPX)
Astronomers were puzzled earlier this year when NASA's Hubble Space Telescope spotted an overabundance of dark matter in the heart of the merging galaxy cluster...
When the first stars blinked on
Dec 06, 2012 (SPX)
As far back in time as astronomers have been able to see, the universe has had some trace of heavy elements, such as carbon and oxygen. These elements, original...
New galaxy census highlights importance of starbursts
Dec 06, 2012 (ESA)
Astronomers have used ESA's Herschel Space Observatory to identify thousands of previously undetected starburst galaxies - among the most prolific stellar facto...
Record-Setting X-ray Jet Discovered
Nov 30, 2012 (SPX)
A jet of X-rays from a supermassive black hole 12.4 billion light years from Earth has been detected by NASA's Chandra X-ray Observatory. This is the most dista...
The Diner at the Center of the Galaxy
Nov 28, 2012 (SPX)
Deep in the heart of the spiral Milky Way galaxy, a hot vortex of matter swirls around a black hole more than a million times as massive as the sun. Many galaxi...
Failed explosions explain most peculiar supernovae
Nov 23, 2012 (SPX)
Supercomputer simulations have revealed that a type of oddly dim, exploding star is probably a class of duds-one that could nonetheless throw new light on the m...
Planck discovers filament of hot gas linking two galaxy clusters
Nov 23, 2012 (ESA)
Scanning the sky at microwave and sub-millimetre wavelengths with Planck, astronomers have unambiguously detected a 'bridge' of hot gas connecting two galaxy cl...
Born-again star foreshadows fate of Solar System
Nov 20, 2012 (ESA)
Astronomers have found evidence for a dying Sun-like star coming briefly back to life after casting its gassy shells out into space, mimicking the possible fate...
LLNL scientists assist in building detector to search for elusive dark matter material
Nov 19, 2012 (SPX)
Lawrence Livermore National Laboratory researchers are making key contributions to a physics experiment that will look for one of nature's most elusive particle...
Instrument Will Observe Spiral Galaxy Near Big Dipper's Handle
Nov 18, 2012 (SPX)

The curious shape of a supernova remnant in a star-forming cloud
Nov 16, 2012 (ESA)
Data from two ESA missions combine in a new view of the peculiar supernova remnant W44. The filamentary shell-like structure, detected by the Herschel Space Obs...
Apocalypse and salvation strategy
Nov 12, 2012 (Voice of Russia)
Life forms on Earth may fully disappear in 2,8 billion years, according to a survey conducted by British scientists earlier this year. The survey said that temp...
Astronomers develop new method to determine neutron star mass
Nov 12, 2012 (ESA)
Astronomers have used INTEGRAL and XMM-Newton to look into the neutron star in IGR J17252-3616, a highly obscured X-ray binary system. The data show how the neu...
