Messier 81, Messier 82, and NGC 3077 are all strongly interacting with each other. [5] Observations of the 21-centimeter hydrogen line indicate how the galaxies are connected. [ 6 ] The gravitational interactions have stripped some hydrogen gas away from all three galaxies, leading to the formation of filamentary gas structures within the group ...
