   Explanation: This sharp telescopic view reveals galaxies scattered
   beyond the stars of the Milky Way, at the northern boundary of the
   high-flying constellation Pegasus. Prominent at the upper right is NGC
   7331. A mere 50 million light-years away, the large spiral is one of
   the brighter galaxies not included in Charles Messier's famous 18th
   century catalog. The disturbed looking group of galaxies at the lower
   left is well-known as Stephan's Quintet. About 300 million light-years
   distant, the quintet dramatically illustrates a multiple galaxy
   collision, its powerful, ongoing interactions posed for a brief cosmic
   snapshot. On the sky, the quintet and NGC 7331 are separated by about
   half a degree.
