Infrared observations show many young stars in this region. B174 is therefore an active star forming region. Dark nebulae are clouds of cold gas with temperatures near absolute zero (-273 °C). They are located in cold, dense regions of larger molecular clouds. Their thickness obstructs the visible spectrum of stars or anything in their path. Only infrared and X-ray observations can be made through the nebula. The dark color is due to microscopic dust particles coated with frozen carbon monoxide and nitrogen that block visible light.
