Arp 72 consists of NGC 5996 (VV 16a and others), the oddly-shaped spiral interacting with NGC 5994 (VV 16b and others), the smaller, less-deformed spiral. Both galaxies are located approximately 178 million light-years away in Serpens Caput.

Light rays from the bright magnitude 4.06 star Kappa Sepentis (HIP 77450) just off the top left corner impacted this image.
