Barnard 174 complex

Image Description and Details:

Barnard 174 (=LDN1164) is a very dense dark nebula, which absorbs starlight behind the nebula. Infrared observations show many young stars in this region. Thus, B174 is an active star-forming region. Barnard 174 is a dark nebula in the constellation Cepheus. Dark nebulae or "fog" as they are sometimes called are clouds of cold gas, at temperatures near absolute zero (-273°C), located in cold, dense areas of larger molecular clouds . Their thickness obstructs the visible spectrum of stars or anything in its path. Only infrared and x-ray observations can be made through fog. The dark color is due to microscopic dust particles coated in frozen carbon monoxide and nitrogen, which block visible light.
