Description

Gravitational interactions of M81 with M82 ("Cigar Galaxy") and NGC 3077 have stripped hydrogen gas away from all three galaxies, forming gaseous filamentary structures in the group.

Moreover, these interactions have allowed interstellar gas to fall into the centers of M82

and NGC 3077, leading to vigorous star formation or starburst activity there.

(Wikipedia)

The faint companion of M 81 Holmberg IX (UGC 5336) is also visible

(It is suspected that this dwarf galaxy was created as a result of a close encounter

that M81 would have had with M82 about 200 ~ 300 million years ago)
