Discovery of Giant X-ray Loop Hints at Cosmic Particle Accelerator
Astronomers have found a vast loop-like structure, 20 light years across, adjacent to the most massive star-forming region known in our galaxy. The loop, which was observed in X-ray wavelengths, is 15 times the size of the Arches Cluster, a star-forming region close to the centre of the Milky Way. This is the first time that such a distinctive and... view more... (2005-03-31)
Astronomers find triple interactions of supermassive black holes to be common in early universe
New cosmological computer simulations produced by a team of astronomers from Northwestern University, Harvard University and the University of Michigan show for the first time that supermassive black holes (SMBHs), which exist at the centers of nearly all galaxies, often come together during triple galaxy interactions. view more (2007-01-09)
New population of faint protogalaxies discovered
Astronomers have found a new population of faint protogalaxies by taking the most sensitive spectroscopic survey ever of a time when the universe was only 15% of its present age. view more (2007-11-29)

The smallest piece of ice reveals its true nature
Collaborative research between scientists in the UK and Germany (published in this week's Nature Materials) has led to a breakthrough in the understanding of the formation of ice. view more (2007-06-21)
Swift XMM-Newton Satellites Tune Into a Middleweight Black Hole
While astronomers have studied lightweight and heavyweight black holes for decades, the evidence for black holes with intermediate masses has been much harder to come by. view more (2009-11-11)
First detection of magnetic field in distant galaxy produces a surprise
Using a powerful radio telescope to peer into the early universe, a team of California astronomers has obtained the first direct measurement of a nascent galaxy's magnetic field as it appeared 6.5 billion years ago. view more (2008-10-02)
Supernova remnant menagerie
The supernova remnant N 63A is a member of N 63, a star-forming region in the Large Magellanic Cloud (LMC). Visible from the southern hemisphere, the LMC is an irregular galaxy lying 160,000 light-years from our own Milky Way galaxy. view more (2005-06-07)
High Energy Mystery lurks at the Galactic Centre
A mystery lurking at the centre of our own Milky Way galaxy - an object radiating high-energy gamma rays - has been detected by an international team of astronomers. Their research, published today (September 22nd) in the Journal Astronomy and Astrophysics, was carried out using the High Energy Stereoscopic System (H.E.S.S.), an array of four... view more...

Scientists 'Weigh' Tiny Galaxy Halfway Across Universe
A tiny galaxy, nearly halfway across the universe, the smallest in size and mass known to exist at that distance, has been identified by an international team of scientists led by two from the University of California, Santa Barbara. view more (2007-10-04)
New Cassini image shows "A" ring contains more debris than once thought
Views of Saturn's stunning ring system from above by the Cassini-Huygens spacecraft now orbiting the planet indicate the prominent A ring contains more debris than once thought, according to a new University of Colorado at Boulder study. view more (2006-04-07)
A new method to weigh giant black holes
How do you weigh the biggest black holes in the universe? One answer now comes from a new and independent technique that UC Irvine scientists and other astronomers have developed using data from NASA's Chandra X-ray Observatory. view more (2008-07-17)
Cosmic engines surprise XMM-Newton
XMM-Newton has been surprised by a rare type of galaxy, from which it has detected a higher number of X-rays than thought possible. The observation gives new insight into the powerful processes shaping galaxies during their formation and evolution. view more (2008-04-08)
Astronomers discover link between supermassive black holes and galaxy formation
A pair of astronomers from Texas and Germany have used a telescope at The University of Texas at Austin's McDonald Observatory together with Hubble Space Telescope and many other telescopes around the world to uncover new evidence that the largest, most massive galaxies in the universe and the supermassive black holes at their hearts grew together... view more...

Isolated Star-Forming Cloud Discovered in Intracluster Space
Subaru and VLT Join Forces in New Study of Virgo Galaxy Cluster [1] At a distance of some 50 million light-years, the Virgo Cluster is the nearest galaxy cluster. It is located in the zodiacal constellation of the same name (The Virgin) and is a large and dense assembly of hundreds of galaxies. The "intracluster" space between the Virgo galaxies... view more... (2003-01-16)
Predicting TB outbreaks based on the first 2 cases
Outbreaks of tuberculosis (TB) may be able to be identified by looking at certain characteristics of the first two patients, according to new research. view more (2008-07-01)
IBEX discovers that galactic magnetic fields may control the boundaries of our solar system
The first all-sky maps developed by NASA's Interstellar Boundary Explorer (IBEX) spacecraft, the initial mission to examine the global interactions occurring at the edge of the solar system, suggest that the galactic magnetic fields had a far greater impact on Earth's history than previously conceived, and the future of our planet and others may... view more...

'Hidden' Milky Way deuterium found
Scientists using NASA's Johns Hopkins University-operated Far Ultraviolet Spectroscopic Explorer satellite have learned that far more "heavy" hydrogen remains in our Milky Way galaxy than expected, a finding that could radically alter theories about star and galaxy formation. view more (2006-08-15)
Iowa State researchers contribute to discovery of gamma rays from starburst galaxy
Iowa State University astrophysicists contributed to the recent discovery that a galaxy quickly creating new stars is also a source of high energy gamma rays. view more (2009-11-03)
Supernova radioisotopes show sun was born in star cluster, scientists say
The death of a massive nearby star billions of years ago offers evidence the sun was born in a star cluster, say astronomers at the University of Illinois at Urbana-Champaign. view more (2006-10-05)
