Bok Globule
Dark concentrated nebula cloud about 1 ly in diameter, containing some ten to a thousand Sol masses of dust and gas, and pertaining to the early stages of star formation. Bok globules are very popular with some cloud harvesting and cloud engineering clades and civilizations, and several now hold collections of habitats called Bok swarms.
Bok swarms that are in the last stages of collapse before the formation of a protostar or protostars are the subject of intense study, and efforts to control the formation of the resulting star system have been made with various degrees of success.
