M81 (left) and M82 (right). M82 is one of two galaxies strongly influenced gravitationally by M81. The other, NGC 3077, is located off the top edge of this image. M81 with satellite galaxy Holmberg IX in the top center-right corner. Only one supernova has been detected in Messier 81. [18]
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 ).
The largest in the Cartwheel Galaxy group, made up of four spiral galaxies [citation needed] Cigar Galaxy: Ursa Major: Appears similar in shape to a cigar. [citation needed] Also known as Messier 82 or M82 [citation needed] Circinus Galaxy: Circinus: Named after the constellation it is located in . [citation needed] Cocoon Galaxy: Canes Venatici
First, it shows wispy edges and scattered dust clouds that are probably a result of gravitational interaction with its larger neighbors, similar to the galaxy M82. Second, this galaxy has an active nucleus. This caused Carl Seyfert in 1943 to include it in his list of galaxies, which are now called Seyfert Galaxies. However, NGC 3077, though an ...

Groups are the most common structures of galaxies in the universe, comprising at least 50% of the galaxies in the local universe. Groups have a mass range between those of the very large elliptical galaxies and clusters of galaxies. [5] Our own galaxy, the Milky Way, is contained in the Local Group of more than 54 galaxies. [6]
