Bok globule. Computer artwork of a small dark nebula, known as a Bok globule, one of the places where stars form. The red background is part of a larger emission nebula, glowing as the hydrogen gas in it heats up. Bok globules are relatively small, only a light year or so across, and colder and richer in dust than other nebulae. | |
