A quasar (IMAGE)
Caption
An artist's impression of a quasar. The black dot in the center represents the supermassive black hole at the center of the quasar. The red-and-yellow spiral surrounding it shows the disc of hot gas falling into the black hole. Some of this gas is ejected as the quasar's wind, which is shown in light blue. The size of the disc shown is comparable to the size of our Solar System.
