'Dropouts' pinpoint earliest galaxies
Astronomers, conducting the broadest survey to date of galaxies from about 800 million years after the Big Bang, have found 22 early galaxies and confirmed the age of one by its characteristic hydrogen signature at 787 million years post Big Bang. view more (2009-11-09)
Black Holes Lead Galaxy Growth, New Research Shows
Astronomers may have solved a cosmic chicken-and-egg problem -- the question of which formed first in the early Universe -- galaxies or the supermassive black holes seen at their cores. view more (2009-01-07)
Rapid star formation spotted in 'stellar nurseries' of infant galaxies
The Universe's infant galaxies enjoyed rapid growth spurts forming stars like our sun at a rate of up to 50 stars a year, according to scientists at Durham University. view more (2009-11-11)
Peering deep into space
People have always wondered where we, our Earth, our galaxy, come from. A group of scientist has now driven that quest one step further and taken a peak at how the stars that gave rise to most of the material found on our universe formed over cosmic history. view more (2009-05-28)
The violent lives of galaxies: Caught in the cosmic matter web
Astronomers are using the NASA/ESA Hubble Space Telescope to dissect one of the largest structures in the Universe as part of a quest to understand the violent lives of galaxies. Hubble is providing indirect evidence of unseen dark matter tugging on galaxies in the crowded, rough-and-tumble environment of a massive supercluster of hundreds of... view more... (2008-01-11)
Orphan stars found in long galaxy tail
Astronomers have found evidence that stars have been forming in a long tail of gas that extends well outside its parent galaxy. This discovery suggests that such "orphan" stars may be much more prevalent than previously thought. view more (2007-09-21)
Mystery of missing hydrogen
Something vital is missing in the far distant reaches of the Universe: hydrogen - the raw material for stars, planets and possible life. view more (2008-11-24)
Durham team discover a cosmic flow of galaxies across one billion light years of the universe
They have discovered that the distribution of dark matter is far less smooth than has been predicted by theorists, and that the Milky Way is among a flow of galaxies moving together in the direction of the constellation Vela in the southern hemisphere. view more (1999-01-29)
A simple survey yields a cosmic conundrum
A survey of galaxies observed along the sightlines to quasars and gamma-ray bursts-both extremely luminous, distant objects-has revealed a puzzling inconsistency. Galaxies appear to be four times more common in the direction of gamma-ray bursts than in the direction of quasars. view more (2006-08-01)
A Curious Pair of Galaxies
The ESO Very Large Telescope has taken the best image ever of a strange and chaotic duo of interwoven galaxies. The images also contain some surprises - interlopers both far and near. view more (2009-03-17)
A Strange Supernova with a Gamma-Ray Burst
On April 25, the BeppoSAX satellite detected a Gamma-Ray Burst from the direction of the constellation Telescopium, deep in the southern sky. Although there is now general consensus that they originate in very distant galaxies, the underlying physical causes of these events that release great amounts of energy within seconds are still puzzling... view more...

Universe's oldest objects emerge from the background
The deepest reaches of space are permeated by a cloak of infrared radiation, an uneven energy swath generated by long-dead objects from the early universe. view more (2006-12-20)
Far away galaxy under the microscope
An international group of astronomers have discovered large disc galaxies akin to our Milky Way that must have formed on a rapid time scale, only 3 billion years after the Big Bang. view more (2006-08-17)
When galaxies collide: Supercomputers reproduce fluid motions of cosmic duet
A wispy collection of atoms and molecules fuels the vast cosmic maelstroms produced by colliding galaxies and merging supermassive black holes, according to some of the most advanced supercomputer simulations ever conducted on this topic. view more (2006-06-01)
Exceptionally deep view of strange galaxy
A spectacular new image of an unusual spiral galaxy in the Coma Galaxy Cluster has been created from data taken by the Advanced Camera for Surveys on the NASA/ESA Hubble Space Telescope. view more (2009-02-06)
Distant 'Super-Starburst' Galaxies Hide Active Black Holes
ROYAL ASTRONOMICAL SOCIETY PRESS NOTICE: view more (2005-03-31)
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)
Galaxy evolution in cyber universe matches astronomical observations in fine detail
Scientists at the University of Chicago have bolstered the case for a popular scenario of the big bang theory that neatly explains the arrangement of galaxies throughout the universe. view more (2006-06-06)
Intense heat killed the Universe's would-be galaxies, researchers say
Our Milky Way galaxy only survived because it was already immersed in a large clump of dark matter which trapped gases inside it. view more (2009-07-01)
Voracious black holes hide their appetite in dusty galaxies
A UK-led team of astronomers reports that they have tracked down an elusive population of black holes growing rapidly hidden behind clouds of dust. view more (2005-08-08)
