Several of the dwarf galaxies in the Hickson Compact Group 31 are slowly merging. The pictured galaxies of Hickson Compact Group 31 will pass through and destroy each other, millions of stars will form and explode, and thousands of nebula will form and dissipate before the dust settles and the final galaxy emerges about one billion years from now. Hickson Compact Group 31 spans about 150,000 light years and lies about 150 million light years away toward the constellation of Eridanus. Image Credit: NASA, ESA, J. English (U.
