Messier 57 is a planetary nebula located in the constellation of Lyra. Often referred to as the Ring nebula as it resembles a small ring visually in a telescope. A planetary nebula is formed when a star in the latter stages of its life swells up into a red giant phase and the outer layers are expelled into the surrounding space as the star contracts down to a white dwarf. The ionizing radiation causes the surrounding gas to fluoresce.

Independently discovered by Charles Messier and Antoine Darquier de Pellepoix in January 1779.
