Arp 272

Arp 272 is a pair of interacting galaxies consisting of the two spiral galaxies NGC 6050 (left) and IC 1179 (right). Arp 272 lies around 450 million light years from Earth in the constellation of Hercules.[1] The galaxies are part of the Hercules Cluster, which is itself part of the CfA2 Great Wall.[6]
