DescriptionThis is an image of SH2-155, the Cave Nebula. It is a dim and very diffuse nebula within a larger nebula complex containing emission, reflection, and dark nebulosity. It is about 2400 light years away in the constellation Cepheus. The nebula gets its name from the dark lane at the eastern side abutting the brightest curve of emission nebulosity which gives the appearance of a deep cave when seen through a telescope visually.
