Description

M82 is one of a pair of galaxies in the constellation Ursa Major that is well known by all amateur astronomers. M82, along with its neighbor M81 can be seen as a pair in the same field of most small telescopes. While M81 is a beautiful spiral, M82 is an irregular type galaxy and furthermore seems to have been disrupted by a relatively close passage some 300 to 600 million years ago of its partner. Irregular lanes of dust and high rate star birth activity can be seen across its central region. The turbulent explosive gas flow is also a strong source of radio noise.

M82 lies at a distance of 12 million light years.
