Andromeda Galaxy (M31)

The nearest large galaxy neighbor to the Milky Way

The Andromeda Galaxy—which is also known as Messier 31, M31, or NGC 224 and was first known as the Andromeda Nebula—is a barred spiral galaxy that lies around 765 kpc (2.5 million light years) from Eath toward the constellation Andromeda. The galaxy stretches around 46 kpc (152,000 light years) across and is the nearest large galaxy neightbor to the Milky Way. The galaxy can be seen with the naked eye on a clear night at a dark site.

Condor obtained this image of the Andromega Galaxy through the Sloan g', r', and i' filters in the autumn of 2021 as part of a program to study the outer regions of nearby galaxies.
