What is the huge large quasar group? The huge large quasar group is just as it sounds, a very huge and large group of quasars. It consists of the most quasars ever found in one group – 73. Quasars are extremely bright discs – so far the brightest objects in the universe – that emit directional radiation and exist light years away. They are created from very massive black holes and emit enough light to energize particles and interfere with our atmosphere if they get close enough to earth.
