- Beschreibung:
- NGC 2359, also known as Thor's Helmet, is an emission nebula in the constellation Canis Major. The nebula is approximately 11.96 thousand light years away and 30 light-years in size. The central star is the Wolf-Rayet star WR7, an extremely hot star thought to be in a brief pre-supernova stage of evolution. It is similar in nature to the Bubble Nebula, but interactions with a nearby large molecular cloud are thought to have contributed to the more complex shape and curved bow-shock structure of Thor's Helmet.
