Description

NGC 2359 is an emission nebula in the constellation Canis Major located just over 8 degrees from Sirius (α Canis Majoris). The nebula is approximately 3,670 parsecs (11.96 thousand light years) and 30 light years in size. Its unusual shape, similar to the helmet of a Viking warrior, has led to it being also known as Thor's Helmet Nebula. The star inside the bubble, called WR 7 (HD 56925), has an apparent magnitude 11.5 and is the source that illuminates this nebula. The fog is the result of the interaction between the stellar wind coming from the hot star and interstellar matter. The wind compresses interstellar matter producing a gas bubble around the star.
