  <div class=

Sharpless 155 (the brownish nebula located below the image's center), also known as the Cave Nebula, Caldwell 9, or LBN 529, is a diffuse bright nebula within a larger nebula complex containing emission, reflection, and dark nebulosity, which is rich in color. It is located in the constellation Cepheus. The nebula gets its name "Cave Nebula" from the dark lane at the eastern side which ends at the brightest curve of emission nebulosity which gives the appearance of a deep cave when seen through a telescope visually.
