Description

Two galaxy groups appear next to each other in the constellation Pegasus.

Stephan's Quintet, in the lower left, consists of four gravitationally interacting galaxies about 290 million light-years away plus a fifth galaxy about 40 million light-years away. Three of the galaxies have distorted shapes, elongated spiral arms, and long, gaseous tidal tails containing myriad star clusters, proof of their close encounters.
The Deer Lick group, in the upper right, consists of the large spiral galaxy NGC 7331, which is about 50 million light-years away, plus several other smaller-appearing galaxies that are about ten times farther. Several other distant galaxies are scattered across the image.
