Description

Thor's Helmet (also known as NGC 2359 ) is an emission nebula in the constellation Canis Major. The nebula is approximately 11,960 light years away from Earth.
Wolf-rayet star WR7 is the central star, an extremely hot star, in probably pre-supernova stage.
The structure of the helmet of Thor, may caused by interactions with a nearby large molecular cloud and curved bow-shock emitted by winds from the central star (HD56925).
