ARP 227 and NGC 474
Astrobin Top Pick
Hampshire Astronomical Group Picture of the Month October 2019
Featured on the BBC The Sky At Night website www.bbc.co.uk/programmes/p07qcd0m/p07qcbd1
An unusual group of galaxies (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.
