      Explanation: An intriguing pair of interacting galaxies, M51 is the   
      51st entry in Charles Messier's famous catalog. Perhaps the original   
      spiral nebula, the large galaxy with whirlpool-like spiral structure   
      seen nearly face-on is also cataloged as NGC 5194. Its spiral arms and   
      dust lanes sweep in front of a companion galaxy (right), NGC 5195. Some   
      31 million light-years distant, within the boundaries of the   
      well-trained constellation Canes Venatici, M51 looks faint and fuzzy to   
      the eye in direct telescopic views. But this remarkably deep image   
      shows off stunning details of the galaxy pair's striking colors and   
      extensive tidal debris. A collaboration of astro-imagers using   
      telescopes on planet Earth combined over 10 days of exposure time to   
      create this definitive galaxy portrait of M51. The image includes 118   
      hours of narrowband data that also reveals a vast glowing cloud of   
      reddish ionized hydrogen gas discovered in the M51 system.
