Bok Globules are fascinating objects. They are pockets of dark cosmic dust and gas, usually containing new born protostars, on their way to becoming fully fledged main sequence stars. They are named after Dutch astronomer Bart Bok who first observed them in the 1940’s.

The Bok Globules here are being created by the interstellar wind and radiation being blasted by the open cluster NGC2244 at the centre of the nebula. This group of young stars are so powerful, they are heating the gas surrounding it to 6 million degrees Celsius, causing it to emit light in the visible spectrum as well as a large amount of X-Rays.
