NGC7331

NGC 7331

NGC 7331 is an unbarred spiral galaxy about 40 million light-years away in the Costellation Pegasus.

The galaxy is similar in size and structure to the Milky Way, and is often referred to as “the Milky Way’s twin”.However, discoveries in the 2000s regarding the structure of the Milky Way may call this similarity into doubt, particularly because the latter is now believed to be a barred spiral, compared to the unbarred status of NGC 7331.
