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)

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:
