A Primordial Quasar - The nearest quasars are now known to be supermassive black holes in the centers of galaxies. Gas and dust that falls toward a quasar glows brightly, sometimes outglowing the entire home galaxy. The quasars that formed in the first billion years of the universe are more mysterious, though, with even the nature of the surrounding gas still unknown.

Quasar- this is a black hole that is the brightest object in the universe and is thousands of times brighter than the stars in a galaxy combined! Light is shot out of either end in extremely long distances. The light we see coming from these today is very old meaning there are no quasars recently. They are all from far away but a new one can appear at any moment
