University of Berkeley Astronomers Discover Largest Known Black Holes

Wednesday, December 7th, 2011

Black HoleUniversity of California, Berkeley Astronomers have discovered the largest black holes known to date. The black holes are estimated to be have masses equivalent to about 10 billion suns each (one black hole being slightly bigger than the other). The two black holes are in clusters of elliptical galaxies greater than 300 million light years away (1 light year is approximately 5.8 trillion miles). (more…)
