Astronomers find the most distant star clusters hidden behind a nearby cluster
Astronomers have discovered the most distant population of star clusters ever seen, hidden behind one of the nearest such clusters to Earth. view more (2007-01-11)
Baffling boxy bulge
When targeting spiral galaxy bulges, astronomers often seek edge-on galaxies, as their bulges are more easily distinguishable from the disc. view more (2009-11-18)
Hubble sees magnetic monster in erupting galaxy
The Hubble Space Telescope has found the answer to a long-standing puzzle by resolving giant but delicate filaments shaped by a strong magnetic field around the active galaxy NGC 1275. It is the most striking example of the influence of these immense tentacles of extragalactic magnetic fields, say researchers. view more (2008-08-21)
Galaxy Cluster Takes It to the Extreme
Evidence for an awesome upheaval in a massive galaxy cluster was discovered in an image made by NASA's Chandra X-ray Observatory. The origin of a bright arc of ferociously hot gas extending over two million light years requires one of the most energetic events ever detected. view more (2007-05-31)
Shedding light on the cosmic skeleton
"Matter is not distributed uniformly in the Universe," says Masayuki Tanaka from ESO, who led the new study. "In our cosmic vicinity, stars form in galaxies and galaxies usually form groups and clusters of galaxies. The most widely accepted cosmological theories predict that matter also clumps on a larger scale in the so-called... view more... (2009-11-03)
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)
Hubble finds ring of dark matter
Astronomers have long suspected the existence of the invisible substance of dark matter as the source of additional gravity that holds together galaxy clusters. view more (2007-05-16)
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)
Suzaku Snaps First Complete X-ray View of a Galaxy Cluster
The joint Japan-U.S. Suzaku mission is providing new insight into how assemblages of thousands of galaxies pull themselves together. view more (2009-05-29)
Newly discovered galaxy cluster in early stage of formation is farthest ever identified
UC Irvine scientists have discovered a cluster of galaxies in a very early stage of formation that is 11.4 billion light years from Earth - the farthest of its kind ever to be detected. view more (2008-04-01)
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. view more (2005-04-01)
Living Fossils Hold Record of 'Supermassive' Kick
The tight cluster of stars surrounding a supermassive black hole after it has been violently kicked out of a galaxy represents a new kind of astronomical object and a fossil record of the kick. view more (2009-07-10)
XMM-Newton digs into the secrets of fossil galaxy clusters
Taking advantage of the high sensitivity of ESA's XMM-Newton and the sharp vision of NASA's Chandra X-Ray space observatories, astronomers have studied the behaviour of massive fossil galaxy clusters, trying to find out how they find the time to form- view more (2006-05-01)
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)
Rogue Black Holes May Roam the Milky Way
It sounds like the plot of a sci-fi movie: rogue black holes roaming our galaxy, threatening to swallow anything that gets too close. In fact, new calculations by Ryan O'Leary and Avi Loeb (Harvard-Smithsonian Center for Astrophysics) suggest that hundreds of massive black holes, left over from the galaxy-building days of the early universe, may... view more...

ESA's XMM-Newton gains deep insights into the distant Universe
Using XMM-Newton, astronomers have obtained the world's deepest 'wide screen' X-ray image of the cosmos to date. Their observations show newly discovered clusters of galaxies and provide insights into the structure of the distant Universe"¦ Unlike grains of sand on a beach, matter is not uniformly spread throughout the Universe. Instead, it... view more... (2003-07-14)
THE MAKING OF THE MILKY WAY HALO
The brightest objects in the halo are the globular clusters. They are large groupings of stars that were formed together in the very early evolutionary phases of the Milky Way, some 12,000 - 14,000 million years ago. This happened soon after the moment when the first structures emerged in the large cloud of primordial hydrogen in which our Galaxy... view more... (1999-02-18)
Astronomers Discover Mysterious New Star Clusters
A UK-led team of astronomers has discovered a completely new type of star cluster around a neighbouring galaxy. view more (2005-04-02)
Mystery of Quintuplet stars in Milky Way solved
For the first time, scientists have identified the cluster of Quintuplet stars in the Milky Way's galactic center, next to the super massive black hole, as massive binary stars nearing the end of their life cycle, solving a mystery that had dogged astronomers for more than 15 years. view more (2006-08-21)
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)
