NGC 2359 Thor's Helmet. Imaged under a full moon. Was worried the details were going to wash out but I am very pleased with the results! Over 6 hrs of exposure.

Thor's Helmet
Image Credit & Copyright: Ritesh Biswas
Explanation: Thor not only has his own day (Thursday), but a helmet in the heavens. Popularly called Thor's Helmet, NGC 2359 is a hat-shaped cosmic cloud with wing-like appendages. Heroically sized even for a Norse god, Thor's Helmet is about 30 light-years across. In fact, the cosmic head-covering is more like an interstellar bubble, blown with a fast wind from the bright, massive star near the bubble's center. Known as a Wolf-Rayet star, the central star is an extremely hot giant thought to be in a brief, pre-supernova stage of evolution. NGC 2359 is located about 15,000 light-years away toward the constellation of the Great Overdog. This remarkably sharp image is a mixed cocktail of data from narrowband filters, capturing not only natural looking stars but details of the nebula's filamentary structures. The star in the center of Thor's Helmet is expected to explode in a spectacular supernova sometime within the next few thousand years.

Thors Hammer
N2359 is a stellar wind-blown shell nebula around the Wolf-Rayet star HD56925 approximately 15,000 light-years from the Earth. It is located in the constellation Canis Major. HD56925 is the bright star located at the center of the main bubble. This type of star is much more massive and hotter than our Sun. Wolf-Rayet stars are rare. Only about 300 are known to exist in the Milky Way. This rarity makes NGC 2359 an interesting object of study and observation. Wolf-Rayet stars expel material in an extremely violent stellar wind with velocities approaching 2000 kilometers per second. The ejected material interacts with the gas and dust around the star producing the bubble structure seen in the image above. The star is ejecting material at a prodigious rate and cannot sustain its extreme behavior for long and it will end its life in a spectacular supernova explosion.
