Description

M81 - Bode´s Galaxy
Messier 81 or M81 (also designated NGC 3031) is a spiral galaxy in the constellation Ursa Major. It has an apparent visual magnitude of 6.9 and its angular diameter is 21x10 arc-minutes. M81 lies at an estimated distance of 12 million light years.

M82 - Cigar Galaxy
Messier 82 or M82 (also designated NGC 3034) is a starburst galaxy in the constellation Ursa Major. It has an apparent visual magnitude of 8.4 and its angular diameter is 9x4 arc-minutes. M82 lies at an estimated distance of 12 million light years.

M82 has an irregular, distorted disk due to the gravitaional interaction of its larger neighbor M81. It is known as a starburst galaxy since it is the site of intense star-forming activity.
