CAMBRIDGE, Mass., Aug. 15 (UPI) -- A galaxy cluster, one of the largest objects in the universe, is breaking several cosmic records for star formation and energy output, U.S. astronomers say.
The Phoenix cluster, located about 5.7 billion light years from Earth, is forming stars at the highest rate ever observed for the middle of a galaxy cluster and is the most powerful producer of X-rays of any known cluster, NASA's Chandra X-ray Observatory in Cambridge, Mass., reported Wednesday.
