Description:
The Ghost Nebula, Sh2-136 or VdB 141 in Cepheus, is a reflection nebula from which several ghostly figures appear to be arising. It lies 1,200 light-years from Earth and is part of the Cepheus Flare molecular cloud complex. At the lower right end of the nebula, a V-shaped structure can be seen which is one lobe of a bipolar outflow originating from a protostar forming within the nebula. The protostar is visible as a dim, diffuse glow at the vertex of the V. The opposite lobe of the bipolar outflow, projecting outward on the far side of the nebula, can be glimpsed just to the left of the bright yellow star above and to the right of the protostar.
