ESO 69-6 (also known as ESO 069-IG006 and AM 1633-682) consists of two interacting galaxies about 650 million light-years away in the constellation of Triangulum Australe. The two galaxies are moving away from us at a speed of almost 14,000 kilometers per second.

The galaxies of this beautiful interacting pair bear some resemblance to musical notes on a stave. Long tidal tails sweep out from the two galaxies: gas and stars were stripped out and torn away from the outer regions of the galaxies. The presence of these tails is the unique signature of an interaction.
