The active core of a quasar, driven by an active black hole, generating radiation. When the black hole stops consuming matter, the radiation dims.Quasars are extremely bright galaxies driven by very active super-massive black holes in their cores. In the early universe, quasars dominated, so astronomers use these objects as a means of understanding how the early universe, and the galaxies it contained, formed.
