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.
