The Horsehead Nebula (B33 or Bernard 33) is a dark nebula that is silhouetted against the diffuse background of IC 434. It is protruding from the Orion B molecular cloud, which is part of the Orion molecular cloud complex. IC 434 is surrounded by a shell of neutral hydrogen gas with the identifier GS206-17+13. The most driving energy behind this expanding shell comes from the blue supergiant Epsilon Orionis.
