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 ).
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 ...
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 .
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]
The Large Magellanic Cloud is a satellite galaxy of the Milky Way, as is another nearby galaxy called the Small Magellanic Cloud. Both are smaller than our galaxy and offer different galactic ...
The smaller galaxy NGC 5195 is tidally interacting with the larger Whirlpool Galaxy, creating its grand design spiral galaxy architecture. [citation needed] M81; M82; NGC 3077; These three galaxies interact with each other and draw out tidal tails, which are dense enough to form star clusters. The bridge of gas between these galaxies is known ...
