Description

This image captures the red hydrogen emission area Sh2-155, located in the constellation of Cepheus at a declination of +63 degrees. Better known as the Cave Nebula, it is located 2400 light years away and has a radius of 35 light-years.

The bright rim of ionized hydrogen gas that forms the cave outline is being energized by the radiation from the two bright stars towards the top of the cave. There appears to be a faint bluish reflection nebula in this same area. Numerous dark lanes, aside from the cave itself, extend throughout the image. The Cave Nebula object is the 9th object in the Caldwell Catalog.
