NGC 2359 (Thor's Helmet) is a prototypical wind blown bubble powered by the extremely massive and unstable Wolf-Rayet star HD 56925. These types of stars represent a late evolutionary phase of massive O-type blue giants which have become unstable in the late stages of their short stellar life. This image is based on data acquired by the Oschin Telescope at the Mount Palomar Observatory.
