About this Image
M 110 (also known as NGC 205) is a dwarf elliptical galaxy about 2.9 million light-years away in the constellation Andromeda.
M 110 is the brightest satellite galaxy of the famous Andromeda Galaxy (M 31) and therefore a member of the Local group of galaxies.
It was discovered by Charles Messier in 1773 but he did not include this object in his catalogue.
M 110 contains some dust and hints of recent star formation, which is unusual for a galaxy of its type.
Several globular clusters have been discovered in M 110, see ref 1.
