The new observations reveal that Messier 87's halo of stars has been cut short, with a diameter of about a million light-years, significantly smaller than expected, despite being about three times the extent of the halo surrounding our Milky Way [1]. Beyond this zone only few intergalactic stars are seen. http://www.physorg.com/news162041045.html Space & Earth Wed, 20 May 2009 12:24:44 EST news162041045 A new Hubble image highlights striking swirling dust lanes and glittering globular clusters in oddball galaxy NGC 7049. http://www.physorg.com/news158329219.html Space & Earth Tue, 07 Apr 2009 13:20:46 EST news158329219 Peering into the tumultuous heart of the nearby Perseus galaxy cluster, Hubble discovered a large population of small galaxies that have remained intact while larger galaxies around them are being ripped apart by the gravitational tug of other galaxies. http://www.physorg.com/news156075674.html Space & Earth Thu, 12 Mar 2009 11:21:35 EST news156075674 About 100 million light-years away, in the constellation of Piscis Austrinus (the Southern Fish), three galaxies are playing a game of gravitational give-and-take that might ultimately lead to their merger into one enormous entity. http://www.physorg.com/news155309518.html Space & Earth Tue, 03 Mar 2009 13:32:45 EST news155309518 Astronomers studying new images of a nearby galaxy cluster have found evidence that high-speed collisions between large elliptical galaxies may prevent new stars from forming, according to a paper to be published in a November 2008 issue of The Astrophysical Journal Letters. http://www.physorg.com/news142595942.html Space & Earth Tue, 07 Oct 2008 10:59:02 EST news142595942
