Dimension:( M81) 26.9
× 14.1 (M82) 11 ′.2 × 4 ′.3.
Size: (M81) 6.94 mag. (M82) 8.41 mag.
Constellation: Ursa Major.
Range:( M81) 11.8 ± 0.4 Mly (M82) 11.5 ± 0.8 Mly.

Notes: Messier 81 (additionally referred to as NGC 3031 or Bode’s Galaxy) is a spiral nebula about 12 million light-years away in the constellation Ursa Major. Due to its distance to Earth, huge size as well as energetic stellar nucleus (which harbors a 70 million M ☉ supermassive black opening), Messier 81 has actually been examined thoroughly by specialist astronomers. The galaxy’s plus size and reasonably high brightness additionally make it a preferred target for amateur astronomers.

Messier 82 (additionally referred to as NGC 3034, Cigar Galaxy or M82) is a starburst galaxy about 12 million light-years away in the constellation Ursa Major. It has to do with 5 times extra luminescent compared to the entire Galaxy and one hundred times more luminous than our galaxy’s centre. The starburst task is assumed to be activated by interaction with adjoining galaxy M81, as well as M82 belongs to the M81 Team. As the closest starburst galaxy to our own, M82 is the normal instance of this sort of galaxy.
SN 2014J, a Type Ia supernova, was observed in the galaxy on 21 January 2014.
