[English] M51: The Whirlpool Galaxy

Find the Big Dipper and follow the handle away from the dipper’s bowl until you get to the last bright star. Then, just slide your telescope a little south and west and you’ll come upon this stunning pair of interacting galaxies, the 51st entry in Charles Messier’s famous catalog. Perhaps the original spiral nebula, the large galaxy with well defined spiral structure is also cataloged as NGC 5194. Its spiral arms and dust lanes clearly sweep in front of its companion galaxy (top), NGC 5195. The pair are about 31 million light-years distant and officially lie within the angular boundaries of the small constellation Canes Venatici. Though M51 looks faint and fuzzy to the eye, deep images like this one reveal striking colors and galactic tidal debris.
