Astronomers have spotted an ultrafast star, traveling at a blistering 6 million km/h, that was ejected by the supermassive black hole at the heart at the Milky Way five million years ago. The discovery of the star, known as S5-HVS1, was made by Carnegie Mellon's Sergey Koposov as part of the Southern Stellar Stream Spectroscopic Survey (S5). Located in the constellation of Grus - the Crane - S5-HVS1 was found to be moving ten times faster than most stars in the Milky Way.
