Arp 78 Galaxy
NGC 772 in Aries
also known as Arp 78, is an enormous SA(s)b spiral galaxy, twice the size of our own Milky Way. Arp 78 is included in American astronomer, Halton Arp's Atlas of Peculiar Galaxies, and it is NGC 770, the dwarf elliptical galaxy above it at 11 o'clock, that is distorting Arp 78's shape via tidal forces.
Many thanks go out to my collaborator and friend, Mike Selby, who acquired and calibrated this fine data.
