The Block Nebula is a reflection nebula located in the central part of Yearn Sector, within the Where The Stars End region of the Empty Stars.

Description (Specifications)[edit]

The Block Nebula is a large dim group of gases and dark clouds measuring around 9 parsecs coreward-rimward by 6 parsecs spinward-trailing. Parsec-sized "pockets" of gas and dust are located to spinward-coreward and to rimward-trailing of the nebula.

  • It is classified as a reflection nebula and is primarily formed of ionized gases, thrown off by the stars at its center many millennia ago.
  • The gases consist of about 90% hydrogen, with the remainder made up of helium, oxygen, nitrogen, and other elements. The clouds have a mean density of 102–106 particles/cm³. Its central regions are relatively denser.

Two separate star systems lie at its core:
