(PhysOrg.com) -- Bursts of star making in a galaxy have been compared to a Fourth of July fireworks display: They occur at a fast and furious pace, lighting up a region for a short time before winking out. http://www.physorg.com/news160318098.html Space & Earth Thu, 30 Apr 2009 13:48:50 EST news160318098 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 (PhysOrg.com) -- Evidence of star birth within a cloud of primordial gas has given astronomers a glimpse of a previously unknown mode of galaxy formation. The cloud, known as the Leo Ring, appears to lack the dark matter and heavy elements normally found in galaxies today. The unexpected discovery comes thanks to instruments aboard NASA's Galaxy Evolution Explorer (GALEX) spacecraft which are sensitive to the ultraviolet radiation emitted by newly formed stars. http://www.physorg.com/news154186484.html Space & Earth Wed, 18 Feb 2009 13:35:40 EST news154186484 (PhysOrg.com) -- A team led by a Yale University astronomer has discovered the least luminous, most dark matter-filled galaxy known to exist. http://www.physorg.com/news140959932.html Space & Earth Thu, 18 Sep 2008 12:32:12 EST news140959932 (PhysOrg.com) -- By analyzing light from small, faint galaxies that orbit the Milky Way, UC Irvine scientists believe they have discovered the minimum mass for galaxies in the universe - 10 million times the mass of the sun. http://www.physorg.com/news139060664.html Space & Earth Wed, 27 Aug 2008 12:57:44 EST news139060664 (PhysOrg.com) -- Using one of the most powerful supercomputers in the world to simulate the halo of dark matter that envelopes our galaxy, researchers found dense clumps and streams of the mysterious stuff lurking in the inner regions of the halo, in the same neighborhood as our solar system. http://www.physorg.com/news137246679.html Space & Earth Wed, 06 Aug 2008 13:04:39 EST news137246679 Globular star clusters, dense bunches of hundreds of thousands of stars, contain some of the oldest surviving stars in the Universe. A new international study of globular clusters outside our Milky Way Galaxy has found evidence that these hardy pioneers are more likely to form in dense areas, where star birth occurs at a rapid rate, instead of uniformly from galaxy to galaxy. http://www.physorg.com/news137154249.html Space & Earth Tue, 05 Aug 2008 11:24:09 EST news137154249
