The Great Galaxy of Andromeda
A starless version of M31 shows the M31 as it was seen just outside of our home galaxy, the Milky way. All the stars in the first photo are located in Our galaxy at maximum distance of few tens of thousands light years. M31 lies at distance of about 2.5 million light years. There is 2.5 million light years of nothing between us and Messier 31. Dim dots at the starless image are more distant galaxies and some hundert of globular clusters in Andromeda.
