M81 Bode’s Galaxy in Ursa Major
Messier 81 (also known as NGC 3031 or Bode’s Galaxy) is a grand design spiral galaxy about 12 million light-years away, with a diameter of 90,000 light years, in the constellation Ursa Major. M81 was first discovered by Johann Elert Bode on 31 December 1774. Thus, it is sometimes referred to as “Bode’s Galaxy”.
The galaxy lies in a region with dense Intergalactic Flux (IFN) which can be seen in the background. Left to M81, the irregular galaxy Holmberg IX can be seen, a satellite galaxy of Messier 81.
