The Messier 81 and Messier 82 galaxies are a pair of galaxies located in the constellation, Ursa Major. M81 (Bode’s Galaxy) is a spiral galaxy that lies approximately 11.8 million light-years away, while M82 (The Cigar Galaxy) is an irregular galaxy at roughly the same distance away from Earth.

These galaxies have a gravitational lock on each other and have affected the shape and composition of one another. Between Messier 81 and Messier 82, you’ll find the Integrated Flux Nebula, but this is extremely faint and difficult to photograph. Bode’s Galaxy and the Cigar Galaxy are members of the M81 Group of galaxies.
