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)
Astronomers get their hands dirty as they lift the veil on galactic dust
There is more to a grain of dust than meets the eye, at least for astronomers as they attempt to probe deeper into distant galaxies. view more (2007-10-15)
Galaxies are born inside dark matter clumps, Cornell study of Spitzer Space Telescope data shows
Try mixing caramel into vanilla ice cream - you will always end up with globs and swirls of caramel. Scientists are finding that galaxies may distribute themselves in similar ways throughout the universe and in places where there is lots of so-called dark matter. view more (2006-04-20)
Discovering teenage galaxies
Staring for the equivalent of every night for two weeks at the same little patch of sky with ESO's Very Large Telescope, an international team of astronomers has found the extremely faint light from teenage galaxies billions of light years away. view more (2007-11-28)
Galaxy collisions dominate the local universe
More than half of the largest galaxies in the nearby universe have collided and merged with another galaxy in the past two billion years, according to a Yale astronomer in a study using hundreds of images from two of the deepest sky surveys ever conducted. view more (2005-12-06)
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)
Colossal Black Holes Common in the Early Universe
Astronomers think that many - perhaps all - galaxies in the universe contain massive black holes at their centers. New observations with the Submillimeter Array now suggest that such colossal black holes were common even 12 billion years ago, when the universe was only 1.7 billion years old and galaxies were just beginning to form. view more (2008-10-17)
Distant Galaxies Are In The Red
According to scientists from the Institute of Astronomy, University of Cambridge, red is the colour favoured by distant galaxies. But the reason for this is still not clear. Working with astronomers in California and Canada, the Cambridge team used a special infrared-sensitive camera to carry out a large-scale survey of distant galaxies. The main... view more...

Chandra catches 'piranha' black holes
Supermassive black holes have been discovered to grow more rapidly in young galaxy clusters, according to new results from NASA's Chandra X-ray Observatory. view more (2007-07-25)
More star births than astronomers have calculated
The "birth rate" for stars is certainly not easy to determine. Distances in the universe are far too great for astronomers to be able to count all the newly formed celestial bodies with the aid of a telescope. view more (2008-10-02)
New deep space images of distant strip of sky to be available on Google
A global project to map a distant strip of the universe is releasing its data today to scientists and the public to be used as part of Google Sky, a new feature of Google Earth. view more (2007-10-04)
Hubble finds large sample of very distant galaxies
New Hubble Space Telescope observations of six spectacular galaxy clusters acting as gravitational lenses have given significant insights into the early stages of the Universe. Scientists have found the largest sample of very distant galaxies seen to date: ten promising candidates thought to lie at a distance of 13 billion light-years (~redshift... view more... (2008-07-25)
IU astronomer's discovery poses challenge to galaxy formation theories
A team led by an Indiana University astronomer has found a sample of massive galaxies with properties that suggest they may have formed relatively recently. view more (2009-04-13)
Black holes, galaxies young and old visible in massive mapping of the night sky
Color images documenting the past 10 billion years of galactic evolution were distributed online this week as part of the first public release of data from a massive project to map a distant region of the universe that combines the efforts of nearly 100 researchers from around the world, including the University of Pittsburgh. view more (2007-10-04)
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)
Monster black holes grow after galactic mergers
An analysis of the Hubble Space Telescope's deepest view of the universe offers compelling evidence that monster black holes in the centers of galaxies were not born big but grew over time through repeated galactic mergers. view more (2006-01-11)
Herschel Space Telescope's SPIRE instrument package makes first-light observations
A scientific instrument package developed in part by the University of Colorado at Boulder for the $2.2 billion orbiting Herschel Space Observatory that was launched in May by the European Space Agency has made its first successful observations, targeting two star-forming galaxies near the Milky Way. view more (2009-07-13)
Galaxy 'Hunting' Made Easy
Astronomers using ESO's Very Large Telescope have discovered in a single pass about a dozen otherwise invisible galaxies halfway across the Universe. The discovery, based on a technique that exploits a first-class instrument, represents a major breakthrough in the field of galaxy 'hunting'. view more (2007-09-17)
From galaxy collisions to star birth: ISO finds the missing link
Data from ISO, the infrared observatory of the European Space Agency (ESA), have provided the first direct evidence that shock waves generated by galaxy collisions excite the gas from which new stars will form. The result also provides important clues on how the birth of the first stars was triggered and speeded up in the early Universe. By... view more... (2005-03-29)
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)
