North is up in this image. The dark Nebula dominant in this image is known as Barnard 143. It lies in the constellation of Aquila. What used to be considered a hole in the sky is now known to astronomers as a dark molecular cloud. Here, a high concentration of dust and molecular gas absorb practically all the visible light emitted from background stars. The eerily dark surroundings help make the interiors of molecular clouds some of the coldest and most isolated places in the universe.  Horizontal FOV is 55'

 

Image center is approximately - Equatorial 2000: RA: 19h 41m 25s Dec: +1100'00"
