   Explanation: Galaxies of the NGC 7771 Group are featured in this
   intriguing skyscape. Some 200 million light-years distant toward the
   constellation Pegasus, NGC 7771 is the large, edge-on spiral near
   center, about 75,000 light-years across, with two smaller galaxies
   below it. Large spiral NGC 7769 is seen face-on to the right. Galaxies
   of the NGC 7771 group are interacting, making repeated close passages
   that will ultimately result in galaxy-galaxy mergers on a cosmic
   timescale. The interactions can be traced by distortions in the shape
   of the galaxies themselves and faint streams of stars created by their
   mutual gravitational tides. But a clear view of this galaxy group is
   difficult to come by as the deep image also reveals extensive clouds of
   foreground dust sweeping across the field of view. The dim, dusty
   galactic cirrus clouds are known as Integrated Flux Nebulae. The faint
   IFN reflect starlight from our own Milky Way Galaxy and lie only a few
   hundred light-years above the galactic plane.
