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.

2015年2月10日 · 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.

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.

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.

2024年1月1日 · Thor’s Helmet (NGC 2359) is an emission nebula in Canis Major that has been relegated to obscurity by the brighter Orion Nebula (M42) in the same part of the sky. Like many HII regions,...

NGC 2359 is also known as "Thor's Helmet" due to its distinctive shape. The "helmet" shape is a gas bubble formed by a very energetic Wolf-Rayet star (HD56925) in the center of this bubble. The bubble...

The Thor's Helmet Nebula, also known as NGC 2359, is an emission nebula located in the constellation of Canis Major. It gets its name due to its resemblance to the helmet of the Norse god Thor. This n...

2021年12月13日 · "NGC 2359 is an emission nebula in the constellation Canis Major. The nebula is approximately 3,670 parsecs (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.

2010年3月23日 · NGC 2359, A bright nebula surrounding a Wolf-Rayet Star: This ring-shaped nebulosity results from the interaction between the stellar wind of a central Wolf-Rayet star and the interstellar matter. The wind compresses the interstellar matter and produces a bubble of gas around the star.

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.
