Gravitational interactions of M81 with M82 and NGC 3077 [29] have stripped hydrogen gas away from all three galaxies, forming gaseous filamentary structures in the group. [29] 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. [29]
The M81 Group is a galaxy group in the constellations Ursa Major and Camelopardalis that includes the galaxies Messier 81 and Messier 82, as well as several other galaxies with high apparent brightnesses. [1] The approximate center of the group is located at a distance of 3.6 Mpc, making it one of the nearest groups to the Local Group. [1]
Messier 82 (also known as NGC 3034, Cigar Galaxy or M82) is a starburst galaxy approximately 12 million light-years away in the constellation Ursa Major.It is the second-largest member of the M81 Group, with the D 25 isophotal diameter of 12.52 kiloparsecs (40,800 light-years).
NGC 3077 is a small disrupted elliptical galaxy, a member of the M81 Group, which is located in the northern constellation Ursa Major.Despite being similar to an elliptical galaxy in appearance, it is peculiar for two reasons.

The spiral arms of a grand design galaxy extend clearly around the galaxy, covering a significant portion of the galaxy's circumference. As of 2002, approximately 10 percent of all currently known spiral galaxies are classified as grand design type spirals, [1] including M51, M74, M81, M83, and M101.
Detection of such motion is used to support the theory that quasars, BL Lacertae objects and radio galaxies may all be the same phenomenon, known as active galaxies, viewed from different perspectives. [102] [103] It is proposed that the nucleus of M87 is a BL Lacertae object (of lower luminosity than its surrounds) seen from a relatively large ...
The galaxy is a member of the M81 Group, a group of galaxies located at a distance of approximately 11.7 Mly (3.6 Mpc) from Earth. [3] The group also contains the spiral galaxy Messier 81 and the starburst galaxy Messier 82. [3] NGC 4236 is located away from the central part of the M81 group at a distance of 14.5 Mly (4.45 Mpc) from Earth. [4]
