A massive black hole is likely being ejected from its host galaxy according to new data from Chandra and other telescopes. CID-42 (also known as CXOC J100043.1+020637) is a galaxy quasar about 4 billion light years from Earth in the constellation Sextans. It is believed to have a supermassive black hole at its center. CID-42 is thought to be the result of a galaxy collision between two smaller galaxies. It has a distinctive trail of stars extending many light years. When this galaxy collision occurred, the supermassive black holes in the center of each galaxy also collided. The two black holes then merged to form a single black hole, that recoiled from gravitational waves produced by the collision, giving the newly merged black hole a sufficiently large kick for it to eventually escape from the galaxy and is being ejected out of the galaxy at several million miles per hour.Release date June 4, 2012.
