Basilisk Nebula
The Basilisk Nebula is an emission nebula located in the heart of Tarchon Sector, within the Where The Stars End region of the Empty Stars.
- It is an astrographic feature and a nebula.
Description (Specifications)[edit]
The Basilisk Nebula is a group of bright nebulae and dark clouds measuring around 10 parsecs coreward-rimward by 13 parsecs spinward-trailing. The Basilisk's Eye system lies at its core.
- It is classified as an emission nebula and is primarily formed of ionized gases, thrown off by the supergiant primary star of the Basilisk's Eye system many millennia ago.
- The gases consist of about 90% hydrogen (H2), with the remainder made up of helium (He), oxygen (O2), nitrogen (N2), and other elements. The clouds have a mean density of 102–106 particles/cm³.
- The gases primarily emit red light, though other colors can be seen: the source of ionization is high-energy photons emitted from the Basilisk's Eye supergiant star.
A quaternary star system lies at the heart of the nebula:
