M81 is the largest galaxy visible in the image. M81 is gravitationally interacting with M82 just to the left of it, a big galaxy with an unusual halo of filamentary red-glowing gas, and NGC 3077 at the bottom of the image. Around the image many other galaxies from the M81 Group of galaxies can be seen, NGC2976 is at the upper right corner. Together with other galaxy congregates including our Local Group of galaxies and the Virgo Cluster of galaxies, the M81 Group, a group of 34 galaxies located in the constellation Ursa Major, is part of the expansive Virgo Supercluster of Galaxies.
M81, also known as Bode's Galaxy, and M82, also known as Cigar Galaxy, are about 12 million light-years away from the Earth.
