Stars in globular clusters are generally extremely old, with ages of 12-13 billion years. However, a small fraction of them appear to be significantly younger than the average population and, because they seem to have been left behind by the stars that followed the normal path of stellar evolution and became red giants, have been dubbed blue stragglers. http://www.physorg.com/news180783454.html Space & Earth Wed, 23 Dec 2009 13:00:01 EST news180783454 Researchers have discovered evidence that blue stragglers in globular clusters, whose existence has long puzzled astronomers, are the result of 'stellar cannibalism' in binary stars. In other words, binary stars are eating each other and turning into a blue straggler. http://www.physorg.com/news151160938.html Space & Earth Wed, 14 Jan 2009 13:08:58 EST news151160938 (PhysOrg.com) -- Black holes are sometimes huge cosmic beasts, billions of times the mass of our sun, and sometimes petite with just a few times the sun's mass. But do black holes also come in size medium? A new study suggests that, for the most part, the answer is no. http://www.physorg.com/news138464066.html Space & Earth Wed, 20 Aug 2008 15:14:26 EST news138464066 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
