Explanation: This wide, sharp telescopic view revealsgalaxies scattered beyond the stars and faintdust nebulaeof the Milky Way at the northern boundary of the high-flying constellationPegasus. Prominent at the upper right isNGC 7331. A mere 50 million light-years away, the large spiral is one of the brighter galaxies not included inCharles 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, itspowerful, ongoinginteractions posed for a brief cosmic snapshot. On the sky, thequintet and NGC 7331 are separated by about half a degree.
