NGC 1531 + 2

NGC 1532 (PGC 14638, ESO 359-27 and others) is a large, edge-on spiral galaxy located approximately 65 million light-years away in Eridanus. Interaction with dwarf galaxy NGC 1531 (PGC 14635, ESO 359-26 and others) above it is causing the distorted shape.

ESO 359-29 (PGC 14664 and others) is the interesting galaxy at below and to the left of NGC 1532.
