Description

The latest image of M31, better known as The (Great) Andromeda Galaxy.
Located in the constellation Andromeda, it is our closest (normal) galaxy companion at a distance of 2.5 million light years.
The Andromeda Galaxy is the largest galaxy of the Local Group, which also contains our own Milky Way, the Triangulum Galaxy (M33), and about 50 other smaller galaxies.

In a reasonably dark location it is possible to see this galaxy with the naked eye.
The 2 bright objects are 2 companion galaxies, M32 (above) and M110 (below).

Image comments
