Stephan's Quintet NGC 7317, 18a 18b, 19, 20, 20c
Constellation: Pegasus
Four of the five galaxies in Stephan's Quintet form a physical association and will likely merge with each other. NGC 7320 is actually a foreground galaxy about seven times closer to Earth than the rest of the group. Three of the galaxies have distorted shapes, elongated spiral arms, and long, gaseous tidal tails containing myriad star clusters, proof of their close encounters. These interactions have sparked a frenzy of star birth in the central pair of galaxies. Radio observations in the early 1970s revealed a mysterious filament of emission which lies in inter-galactic space between the galaxies in the group.
