About this image

An unusual group of galaxies i(ARP 227) in the constellation of Pisces. Outer shells may have been created from gravitational interaction between galaxies. The largest galaxy is NGC 474. It is 100 million light years away, and about 250,000 light years across. The outer shells are extremely faint and have necessitated 1800s luminance exposures.
