The main galaxy in this image is NGC7331 but this field of view contains Stephan’s Quintet and the Deer Lick Group.  These are two well-known visual groupings of galaxies that appear close to each other in the constellation Pegasus. Stephan’s Quintet (upper left center), also known as Hickson Compact Group 92 (HGC 92), is a grouping of five galaxies, although only four of them are gravitationally interacting. The fifth galaxy, NGC 7320, is a foreground object much closer to Earth, at about 40 million light-years away, while the other four are significantly more distant at about 290 million light-years. These four interacting galaxies will likely eventually merge. The Deer Lick Group, named by amateur astronomer Tom Lorenzin, is centered around the prominent spiral galaxy NGC 7331, which is about 40 million light-years from Earth. Surrounding it are four other galaxies, sometimes called the “fleas,” which are not gravitationally bound to NGC 7331 or to each other, but appear in the same field of view. These “fleas” are also much farther away, at a distance of around 300 million light-years. While appearing together in the night sky, both of these “groups” are actually a mix of nearby and very distant galaxies.  Written by Gemini AI.
