Hubble has captured quasar PG 1012+008, located 1.6 billion light-years from Earth, merging with a bright galaxy (the object just below the quasar).

The two objects are 31,000 light-years apart, but the swirling wisps of dust and gas surrounding the quasar and galaxy provide strong evidence for an interaction between them.

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.
