A star almost old as the Universe has been discovered just so 190 lyr away from us. Now this is a really cool result and could have some important consequences for the evolution of the first generation of stars.

NASA’s Chandra X-ray Observatory has discovered an extraordinary outburst by a black hole in the spiral galaxy M83, located about 15 million light years from Earth. 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.
