Quasars are the brightest and some of the most distant celestial bodies we know. The quasars themselves can burn up to the energy of a trillion suns and recent evidence shows that this may all happen because of black holes. What we know about quasars is that they have great energy, but are not immense in size (Beardsley 26).

The dominant view is that a supermassive black hole is consuming gas clouds and creating an acceleration disk that moves the gas near luminous speeds. The friction caused by this disk would create light and other radiation (Beardsley 26).

Additionally, the environment that most all quasars appear to be in are at the center of luminous galaxies. What this means is that the quasar could indeed be consuming gas clouds since galaxies are where these gas clouds could be found. Also, when a quasar galaxy and another galaxy collide, the unfortunate other galaxy is left with missing parts or heavy distortion suggesting that the quasar has captured gas clouds from the other galaxy as well (Beardsley 28).

Finally, quasars also seem to be emitting plasma jets, in which radio-emitting gas clouds are released through two directly opposite poles. The only explanation so far of this type of phenomena is the acceleration disk of a black hole (Beardsley 29).
