NGC 7331, a spiral galaxy, lies 40M light-years from earth. Other members of this galactic group (the “Deer Lick Group” that appear here as fuzzy blobs) lie much farther away (>300M LY). Often considered a “twin” (in terms of size and structure) to The Milky Way, NGC 7331 has one unusual difference: the central core of NGC 7331 rotates in opposite direction from rotation of its disk!
