Barnard 163 is a dark nebula of dust and gas so thick that visible light can't shine through it. It is observable because it obscures light from other sources in the background. In this case, the red glow in the background results from IC 1396, a large emission nebula that houses the Elephant's Trunk Nebula. Barnard 163 lies about 3000 light-years from Earth and is part of Cepheus constellation.
