NGC 2359 (also known as Thor's Helmet) is an emission nebula [3] in the constellation Canis Major. The nebula is approximately 3,670 parsecs (11.96 thousand light years) away and 30 light-years in size.

Thor’s Helmet is an emission nebula located in the southern constellation Canis Major. Its designation in the New General Catalogue is NGC 2359. The nebula is 30 light years in size and lies at a distance of 11,960 light years from Earth.

NGC 2359 is located about 15,000 light-years away in the constellation of the Great Overdog. The remarkably sharp image is a mixed cocktail of data from broadband and narrowband filters using three different telescopes.

Thor’s Helmet is composed of cosmic dust and gas, which astrophotography reveals to have a blue-green appearance. NGC 2359 spans roughly 30 light-years across and appears as an interstellar bubble inflated by a central Wolf-Rayet star.

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 by a fast wind from the bright, massive star near the bubble's center.

NGC 2359: Image by David Malin using the 3.9m-Anglo Australian Telescope Physical Properties. It is an emission nebula around a 10.4 mag Wolf-Rayet star (WR). These stars are characterized by very high temperatures and an extremely strong mass loss due to stellar winds.

2010年4月30日 · This heroic image from WISE is of a special cloud of dust and gas in the constellation Canis Major catalogued as NGC 2359.
