NASA's Chandra X-ray Observatory image of an extraordinary outburst by a black hole in the spiral galaxy M83, located about 15 million light years from Earth, is shown in this handout released July 13, 2012. Using Chandra, astronomers found a new ultraluminous X-ray source, or ULX. These objects give off more X-rays than most normal binary systems in which a companion star is in orbit around a neutron star or black hole.
