NGC 5128: Centaurus A

This beautifully interesting galaxy is easily visible from the southern hemisphere and from low northern latitudes. At 12 million lightyears away, it gives astronomers an exciting opportunity to study active galactic nuclei and galaxy evolution. The Chandra X-ray observatory has been observing NGC 5128 intermittently since its launch in 1999. Bright X-ray emission from the center of this galaxy leads astronomers to conclude that it contains a supermassive black hole. The odd shape of the galaxy is thought to be a result of a long-past collision with another galaxy.
