M81 (NGC 3031) is a spiral galaxy located in the Ursa Major constellation at about 12.0 million light-years from the Milky Way. Its diameter is relatively modest at only 87,000 light years.

In this picture we can see the jets of ionised hydrogen, perpendicular to the disc of the galaxy.
In the upper left corner we see Ngc 3077 at the same distance. It is also under the gravitational effects of the other two galaxies.
Also visible in the picture: IFN (Integrated Flux Nebulea), a dusty gas in the foreground that belongs to our Galaxy.
