Hubble has captured evidence of a dance between two merging galaxies. The galaxies may have orbited each other several times before merging, leaving distinct loops of glowing gas around quasar IRAS13218+0552. The quasar is 2 billion light-years from Earth. The elongated core in the center of the image may comprise the two nuclei of the merging galaxies.

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.
