M51 Whirlpool galaxy.

Known as a grand design spiral galaxy. M51 is actually two interacting galaxies, the smaller galaxy being that of NGC 5195. Laying at the outermost tip of one of M51's spiral arms. The two galaxies have spent the last several million years gliding past one another. Galaxies such has the Whirlpool that lie face on to us from our viewpoint here on Earth, make for great study material for astronomers.

Charles Messier is credited with discovering the Whirlpool galaxy in 1773. It can be found 31 million light years away close to the tail of the Great Bear.
