Description

CG30 & 31 are cometary globules in the Puppis constellation, around 1000 light years from earth.

Cometary globules are essentially regions of very compact dust, surrounded by hot ionized gas. They’re shaped almost like a comet, hence the name.

While the origins of these structures (why this exact shape?) is not precisely determined yet; the most likely hypothesis suggests that these are your typical molecular clouds that were shaped by the blast wave(s) of nearby supernova(e).
