A stunning composite image of Hickson Compact Group 31, a group of dwarf galaxies in the constellation Eridanus, merging over a billion years. The image, created from data from Spitzer, GALEX, and Hubble telescopes, shows colliding galaxies, stellar bridges, and trails of stars indicating a dynamic galactic dance. This cosmic collision will eventually form a single elliptical galaxy.
