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)

X-ray satellites discover the biggest collisions in the Universe
The orbiting X-ray telescopes XXM-Newton and Chandra have caught a pair of galaxy clusters merging into a giant cluster. The discovery adds to existing evidence that galaxy clusters can collide faster than previously thought.   view more (2007-07-18)

Largest ever survey of very distant galaxy clusters completed
An international team of researchers led by a UC Riverside astronomer has completed the largest ever survey designed to find very distant clusters of galaxies.   view more (2009-07-01)

GALAXY CLUSTERS, NEAR AND FAR, HAVE A LOT IN COMMON
ROYAL ASTRONOMICAL SOCIETY PRESS NOTICE:   view more (2005-03-28)

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)

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)

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)

Cosmic thermostats provide clue to 30 year old astronomy puzzle (Embargoed until 1900 hrs London time Wednesday 17 July 2002)
A cosmic phenomenon involving pockets of hot gas in space which appear not to cool down has been puzzling astronomers for three decades. Now new research by Dr Christian Kaiser at the University of Southampton and Professor Marcus Brüggen of the International University Bremen, Germany, shows that the energy of the hot gas is actually... 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)

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 reveals the origin of elements in galaxy clusters
Deep observations of two X-ray bright clusters of galaxies with ESA's XMM-Newton satellite allowed a group of international astronomers to measure their chemical composition with an unprecedented accuracy.   view more (2006-05-11)

NASA's Swift satellite images a galaxy ablaze with starbirth
Combining 39 individual frames taken over 11 hours of exposure time, NASA astronomers have created this ultraviolet mosaic of the nearby "Triangulum Galaxy."   view more (2008-02-26)

Stripped down: Hubble highlights 2 galaxies that are losing it
Ram pressure is the drag force that results when something moves through a fluid - much like the wind you feel in your face when bicycling, even on a still day - and occurs in this context as galaxies orbiting about the centre of the cluster move through the intra-cluster medium, which then sweeps out gas from within the galaxies.   view more (2009-09-30)

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)

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...

Hubble sees dark matter ring in a galaxy cluster
A team of astronomers used the Hubble Space Telescope to find the best evidence yet for the existence of dark matter, present in the form of a ghostly ring in a galaxy cluster.   view more (2007-05-17)

Ghostly glow reveals galaxy clusters in collision
A team of scientists, including astronomers from the Naval Research Laboratory (NRL), have detected long wavelength radio emission from a colliding, massive galaxy cluster which, surprisingly, is not detected at the shorter wavelengths typically seen in these objects.   view more (2008-10-16)

Dark matter mystery deepens in cosmic 'train wreck'
Astronomers have discovered a chaotic scene unlike any witnessed before in a cosmic "train wreck" between giant galaxy clusters.   view more (2007-08-17)

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)

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)
