Bok globule

(dense molecular cloud)

A Bok globule is a small, dense volume of dust and gas within an HII region, typically of 2 to 50 solar masses and a fraction of a parsec across. Signs suggest they contain star formation, signs from ultraviolet observation and from the frequency of hot young stars nearby. A cometary globule (CG) is a Bok globule showing a comet-like tail, due to sufficiently intense ultraviolet to push out some material.
