Description

The Cave Nebula ( Sharpless 2-155, Caldwell 9) is part of an extensive region of ionized hydrogen gas region. Sharpless 2-155 is a dim and very diffuse nebula within a larger nebula complex containing emission, reflection, and dark nebulosity. It is located in the constellation Cepheus and associated with the Cepheus B giant molecular cloud, laying at a distance of about 2800 light-years. Part of the cloud is illuminated by a pack of hot, young stars known as the Cepheus OB3 association.
