Galaxies that contain a compact highly luminous core that emits intense radiation are known as active galaxies. The source of the radiation is believed to be a vast disc of shredded stars and other matter being swallowed by a central supermassive black hole. At just 11 million light years away, the enormous elliptical galaxy Centaurus A is the closest of these active galaxies.
