About This Photograph

The Whirlpool Galaxy (also known as Messier 51a, M51a,
or NGC 5194) is an interacting[4] grand-design[5] spiral
galaxy located at a distance of approximately 23 million
light-years in the constellation Canes Venatici. It is one of
the most famous spiral galaxies in the sky. The galaxy
and its companion (NGC 5195) are easily observed by
amateur astronomers, and the two galaxies may even be
seen with binoculars.[6] The Whirlpool Galaxy is also a
popular target for professional astronomers, who study it
to further understanding of galaxy structure (particularly
structure associated with the spiral arms) and galaxy
interactions.
