Rogue Stars Ejected from the Galaxy are Found in Intergalactic Space
May 09, 2012 (SPX)
It's very difficult to knock a star out of the galaxy. In fact, the main mechanism that astronomers have come up with that can give a star the two-million-plus ...
Homing in on supernova origins
May 09, 2012 (SPX)
Type Ia supernovae are important stellar phenomena, used to measure the expansion of the universe. But astronomers know embarrassingly little about the stars th...
One Supernova Type, Two Different Sources
May 09, 2012 (SPX)
The exploding stars known as Type Ia supernovae serve an important role in measuring the universe, and were used to discover the existence of dark energy. They'...
Subaru-Led Team Discovers a Rare Stellar Disk of Quartz Dust
May 09, 2012 (SPX)
A research team of Japanese astronomers led by Dr. Hideaki Fujiwara (Subaru Telescope) has discovered a main-sequence star that is surrounded by a rare disk of ...
Science Nugget: Lightning Signature Could Help Reveal the Solar System's Origins
May 09, 2012 (SPX)
Every second, lightning flashes some 50 times on Earth. Together these discharges coalesce and get stronger, creating electromagnetic waves circling around Eart...
First light: NIST researchers develop new way to generate superluminal pulses
May 08, 2012 (SPX)
Researchers at the National Institute of Standards and Technology (NIST) have developed a novel way of producing light pulses that are "superluminal"-in some se...
Black hole caught red-handed in stellar homicide
May 04, 2012 (SPX)
Astronomers have gathered the most direct evidence yet of a supermassive black hole shredding a star that wandered too close. Supermassive black holes, weighing...
Sifting through dust near Orion's Belt
May 04, 2012 (SPX)
Dust may sound boring and uninteresting - the surface grime that hides the beauty of an object. But this new image of Messier 78 and surroundings, which reveals...
A Cluster Within A Cluster
May 02, 2012 (SPX)
The star cluster NGC 6604 is shown in this new image taken by the Wide Field Imager attached to the 2.2-meter MPG/ESO telescope at the La Silla Observatory in C...
Dusty Stellar Nurseries from the Dark Side of a Galaxy
May 02, 2012 (SPX)
One of the world's most powerful cameras, SCUBA-2 is producing its first detailed images of our neighbouring galaxies, revealing previously undetected vast pock...
Meeting Converges On Gemini Observatory Recent And Potential Scientific Impact
May 02, 2012 (SPX)
In mid-July 2012, astronomers from around the world will converge in San Francisco, California, to discuss recent and future science from the Gemini Observatory...
NMSU's Apache Point Observatory team observes record 103,000 spectra in March
May 02, 2012 (SPX)
When the sun goes down, researchers and staff at New Mexico State University's Apache Point Observatory go into high gear, mapping the universe one pinpoint at ...
Rogue stars ejected from the galaxy are found in intergalactic space
May 02, 2012 (SPX)
It's very difficult to kick a star out of the galaxy. In fact, the primary mechanism that astronomers have come up with that can give a star the two-million-plu...

May 02, 2012 (SPX)
Penn State University astronomers using the world's largest radio telescope, at Arecibo, Puerto Rico, have discovered flaring radio emissions from an ultra-cool...
Astronomers Find Possible Secret of the Origin of Brown Dwarfs
May 02, 2012 (SPX)
The origin of brown dwarfs is one of the great unsolved mysteries facing astrophysicists today. In a new study published in The Astrophysical Journal, Western's...
Old star, new trick
May 02, 2012 (SPX)
The Big Bang produced lots of hydrogen and helium and a smidgen of lithium. All heavier elements found on the periodic table have been produced by stars over th...
'Faster-ticking clock' indicates early solar system may have evolved faster than we think
May 02, 2012 (SPX)
Our solar system is four and a half billion years old, but its formation may have occurred over a shorter period of time than we previously thought, says an int...
