Andromeda and its largest satellite galaxies

My amateur astrophotographer friends Maxence Guilbert and Yanis Hodaibi took this amazing picture of Andromeda (M31): that’s  the closest galaxy to the Milky Way (with a distance of 2.5 million light-years), located near the Andromeda constellation. You can also see its largest satellite galaxies: M110 (above) and M32 (underneath M31, appearing as a small dot).
