NGC 2359

A Wolf-Rayet star is “blowing bubbles” on its way to a probable supernova explosion. It is the white star in the central part of the “teal” colored bubble. The teal or aquamarine color denotes double ionized oxygen, and the reddish regions are ionized hydrogen. Both are caused by the radiation flooding from the Wolf-Rayet star into a neighboring molecular cloud. (Object is also called “Thor’s Helmet”.)
