Located in the constellation Ursa Major, the galaxies M81 and M82 are about 12 million light-years away from us. The galaxies are on the same plane, only about 120,000 light-years apart.
M81 and M82 are gravitationally interacting. The resulting tidal forces deform M82 and cause violent stellar activity.
The IFN present in the image are not part of the same local group, but rather belong to our Milky Way.
The acquisitions were made over several sessions and several sites.
