Concept information
Preferred term
Bok globule
Definition
- A small, roughly spherical cloud of interstellar dust and gas that appears as a dark compact globule when viewed against the background of an H II region. Bok globules range in mass from about 1 to 1,000 or more solar masses, and in size from about 10,000 astronomical units to 3 light-years. They typically have temperatures of around 10 Kelvin. Bok globules are thought to represent a stage in the collapse of a dense fragment of molecular clouds that are in the process of forming new stars.
