Irregular Galaxy ESO 99-4

ESO 99-4 is an irregular galaxy that is probably the remnant of a galactic merger. As seen in this image taken by Hubble’s Advanced Camera for Surveys, the main body of the galaxy is largely obscured by dark bands of dust. ESO 99-4 lies in a rich field of foreground stars and is found in the constellation of Triangulum Australe, the Southern Triangle, about 400 million light-years away.
