description B72 Overview
B72, widely known as the Snake Nebula, is a dark molecular cloud located in the constellation Ophiuchus. It is composed of dense, opaque cosmic dust that completely obscures the light from background stars, creating a distinct, winding S-shaped silhouette. The nebula was cataloged by astronomer Edward Emerson Barnard in the early 20th century as part of his comprehensive survey of dark nebulae. It is a target for amateur astronomers using telescopes to observe complex interstellar formations.
