“Thor’s Helmet” by Adam Block

Astronomy Photographer of the Year 2015

1 August 2015 Astronomy Now

The distinctive shape of the nebula NGC 2359 has led to it also being known as Thor’s Helmet, resembling the headgear of the Norse God (and Marvel superhero). Around 11 thousand light-years away, the overall bubble shape is mainly due to interstellar material swept up by the winds of the nebula’s central Wolf-Rayet star, an extremely hot giant thought to be in a pre-supernova stage.
