COMMENTS ON THE PHOTO:
On the left, M81 (NGC 3031) is a spiral galaxy located in the Big Dipper constellation about 12.0 million light years from the Milky Way. Its diameter is relatively modest at only 87,000 light years.
On the right, M82 (also known as NGC 3034 and the Cigar Galaxy) is a spiral galaxy located about 12.7 million light years away. It is a so-called starburst galaxy, as it has an exceptional rate of star formation, due to the gravitational interaction with M 81, and the rate of star formation is ten times greater than in an isolated galaxy.
In this picture we can see the ionised Hydrogen jets, 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.
