NGC 7331 sits about 50 million light-years from Earth and has been billed as a twin of our own Milky Way galaxy because of its similar mass, star count and spiral arm shapes. Skywatchers Paul Mortfield and Dietmar Kupke recorded this view of NGC 7331 on Oct. 4, 2005 during a nightly observing program run by Kitt Peak.
