The Coalsack Dark Nebula (or simply the Coalsack) is the most prominent dark nebula in the skies, easily visible to the naked eyeas a dark patch silhouetted against the southern Milky Way. The Coalsack is located at a distance of approximately 600 light years away from Earth, in the constellation Crux. The Coalsack is not present in the New General Catalogue and in fact does not have an identification number (outside of the Caldwell Catalogue, in which it is C99).
In Inca astronomy this nebula was called Yutu meaning a partridge.
