(PhysOrg.com) -- Our Milky Way galaxy is surrounded by some 200 compact groups of stars, containing up to a million stars each. At 13 billion years of age, these globular clusters are almost as old as the universe itself and were born when the first generations of stars and galaxies formed. Now a team of astronomers from Germany and the Netherlands have conducted a novel type of computer simulation that looked at how they were born - and they find that these giant clusters of stars are the only survivors of a 13 billion year-old massacre that destroyed many of their smaller siblings. The new work, led by Dr. Diederik Kruijssen of the Max Planck Institute for Astrophysics in Garching, Germany, appears in a paper in the journal Monthly Notices of the Royal Astronomical Society. http://phys.org/news248428931.html Space & Earth Tue, 14 Feb 2012 08:20:02 EST news248428931 (PhysOrg.com) -- European Southern Observatory astronomers have produced a spectacular new image of the famous Atoms-for-Peace galaxy (NGC 7252). This galactic pile-up, formed by the collision of two galaxies, provides an excellent opportunity for astronomers to study how mergers affect the evolution of the Universe. http://phys.org/news208603767.html Space & Earth Wed, 10 Nov 2010 09:29:51 EST news208603767 (PhysOrg.com) -- Is this one galaxy or two? Astronomer Art Hoag first asked this question when he chanced upon this unusual extragalactic object. http://phys.org/news202133035.html Space & Earth Fri, 27 Aug 2010 13:04:16 EST news202133035 (PhysOrg.com) -- Distant galaxies are not only far away in space. Because it takes time for their light to reach us, they are also very far away in time -- snapshots from the distant past. http://phys.org/news189427357.html Space & Earth Fri, 02 Apr 2010 11:42:58 EST news189427357
