"Quasars reside in a variety of galaxies, from normal to highly disturbed. When seen through ground-based telescopes, these compact, enigmatic light sources resemble stars, yet they are billions of light-years away and several hundred billion times brighter than normal stars."
Astronomers believe that a quasar turns on when a massive black hole at the nucleus of a galaxy feeds on gas and stars.
Soon I will let you know what role they play for life here on Earth and interferometry (for InterpidDreamer in particular.)
