Barnard 92 (abbreviated to B92) is a dark nebula located in the Small Sagittarius Star Cloud. It was discovered by American astronomer Edward Emerson Barnard.
B92 was initially referred to as "the black hole,"[2] given its appearance, after it was first catalogued in 1913.[3] It was later discovered to be a dark nebula, and the title is now misleading, as the name black hole is used in modern astrophysics to describe a region of spacetime in which gravity is too strong for light to escape.
