Chandra data reveal rapidly whirling black holes
A new study using results from NASA's Chandra X-ray Observatory provides one of the best pieces of evidence yet that many supermassive black holes are spinning extremely rapidly. The whirling of these giant black holes drives powerful jets that pump huge amounts of energy into their environment and affects galaxy growth. view more (2008-01-11)
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)
Galaxy cluster smashes distance record
The most distant galaxy cluster yet has been discovered by combining data from NASA's Chandra X-ray Observatory and optical and infrared telescopes. view more (2009-10-23)
XMM-Newton takes astronomers to a black hole's edge
Using new data from ESA's XMM-Newton spaceborne observatory, astronomers have probed closer than ever to a supermassive black hole lying deep at the core of a distant active galaxy. view more (2009-05-28)
Caltech astronomers describe the bar scene at the beginning of the universe
Bars abound in spiral galaxies today, but this was not always the case. A group of 16 astronomers, led by Kartik Sheth of NASA's Spitzer Science Center at the California Institute of Technology, has found that bars tripled in number over the past seven billion years, indicating that spiral galaxies evolve in shape. view more (2008-07-30)
Discovery of most recent supernova in our galaxy
The most recent supernova in our Galaxy has been discovered by tracking the rapid expansion of its remains. This result, using NASA's Chandra X-ray Observatory and NRAO's Very Large Array (VLA), has implications for understanding how often supernovas explode in the Milky Way galaxy. view more (2008-05-15)
Rare galaxies shed light on a dark universe
Researchers based at the Institute for Computational Cosmology (ICC) in Durham and at Caltech in California, have found striking proof that their computer simulations of the universe can accurately predict how galaxies are clustered, so helping to reveal the distribution of dark matter throughout the universe. Using a computer simulation to follow... view more... (2002-04-04)
Galaxies gone wild!
Interacting galaxies are found throughout the Universe, sometimes as dramatic collisions that trigger bursts of star formation, on other occasions as stealthy mergers that result in new galaxies. view more (2008-04-24)
New understanding of the origin of galaxies advanced
A new theory as to how galaxies were formed in the Universe billions of years ago has been formulated by Hebrew University of Jerusalem cosmologists. The theory takes issue with the prevailing view on how the galaxies came to exist. view more (2009-01-22)
X-Rays Examine Colliding Galaxies
Galaxies were once thought of as `island universes` evolving slowly in complete isolation. This is now known not to be the case. By using the world`s most powerful X-ray observatories, UK astronomers are discovering that most of these gigantic star systems interact with each other in a wide variety of ways. During the UK National Astronomy Meeting... view more... (2002-04-07)
Astronomers discover dozens of mini-galaxies
A new survey made with the Anglo-Australian Telescope (AAT) has revealed dozens of previously unsuspected miniature galaxies in the nearby Fornax galaxy cluster. They belong to a class of galaxies dubbed "ultra-compact dwarfs" (UCDs), which was unknown before the same team of astronomers discovered 6 of them in the Fornax cluster in... view more...

The Last Cry Of Matter
'Black holes' are truly black. When an object gets within a certain distance from a black hole, it will get swallowed forever with no chance to escape. That includes light, which means that black holes do not shine. How do astronomers detect black holes if they are unable to see them? Well, to be precise, astronomers do not detect black holes.... view more... (2003-11-27)
Arecibo telescope finds critical ingredients for the soup of life in a galaxy far, far away
Astronomers from Arecibo Observatory radio telescope in Arecibo, Puerto Rico, have detected for the first time the molecules methanimine and hydrogen cyanide - two ingredients that build life-forming amino acids - in a galaxy some 250 million light years away. view more (2008-01-15)
RIT study predicts how fast a black hole can be booted from a galaxy
Scientists have discovered for the first time just how fast a supermassive black hole can be thrown from a galaxy when it merges with another black hole. The crucial factor in producing large "kicks" turns out to be the spin that the black holes carry prior to the merger. view more (2007-05-31)
New space telescope aims to seek out and record explosive gamma ray bursts.
A state of the art space telescope built by scientists at UCL will make its way to the Goddard Space Flight Centre in Maryland, USA on a mission to unravel the mysteries of the universes gamma rays. The telescope - called UVOT - will be one of three telescopes on a special NASA orbiting space observatory planned for launch in 2003. The observatory... view more... (2002-05-31)
Dark and distant heavenly bodies revealing the secrets of star and galaxy formation
British astronomers are releasing the first data from the largest and most sensitive survey of the heavens in infrared light to scientists across Europe. view more (2006-07-24)
Hubble spies shells of sparkling stars around quasar
New images taken with NASA's Hubble Space Telescope - part of a research project led by UC Riverside's Gabriela Canalizo - have revealed the wild side of an elliptical galaxy, nearly two billion light-years away, that previously had been considered mild-mannered. view more (2007-10-26)
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 cluster. view more (2007-03-14)
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)
