Images of NGC 2359
NGC 2359, better known as the Thor's Helmet nebula, is actually more like an interstellar bubble, blown as a fast wind from the bright, massive star near the bubble's center sweeps through a surrounding molecular cloud. The central star is an extremely hot giant Wolf-Rayet star, thought to be in a brief, pre-supernova stage of evolution. It lies about 15,000 light years from Earth in the constellation Canis Major, measuring about 30 light years. It is one of the best known Wolf-Rayet nebular structures, along with NGC 6888, and the name Thor's Helmet is due to its remarkable resemblance to depictions of the headwear donned by the famed Norse god of thunder. This INT image captures striking details of the nebula's filamentary structures. The bluish colour remarks the strong emission due to oxygen atoms in the glowing gas. In fact, it can be visually seen with telescopes of moderate aperture using an [OIII] narrow-band filter. This image of the Thor's Helmet nebula or NGC 2359 was obtained using the Wide Field Camera on the Isaac Newton Telescope (INT). It is a three-colour composite made from data collected using filters to isolate the light emitted by hydrogen alpha (H-alpha), doubly-ionised oxygen (OIII) and single-ionised sulfur (SII) atoms, and coded in the image as red, green and blue respectively.

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 giant thought to be in a brief pre-supernova stage of evolution.

NGC 2359 is a striking emission nebula with an impressive popular name - Thor's Helmet Sure, its suggestive winged appearance might lead some to refer to it as the "duck nebula", but if you were a nebula which name would you choose? By any name NGC 2359 is a bubble-like nebula some 30 light-years across, blown by energetic winds from an extremely hot star seen near the center and classified as a Wolf-Rayet star.
