M(essier) 51 is a (relatively) nearby spiral galaxy lying in the constellation Canes Venatici and close to the border of Ursa Major. Lying approximately 30 million light years away, M51 is actually two galaxies that have (relatively) recently collided, with a tail of gas and dust stretched between the two by their mutual graviational interaction.
