The name Quasar, is a short for Quasi-stellar radio source. Quasars are very bright centers of young galaxies that are very far away. The light they make takes billions of years to reach us, so looking at a quasar is like viewing the birth of a galaxy long, long ago. These ultra-bright objects are likely the centers of active galaxies where super massive black holes are. As material spirals into the black holes, a large part of the mass is converted to energy. It is this energy that we see and thought smaller than our system a single quasar can outshine an entire galaxy of a hundred billion stars.
