Elutähtsat

Elutähtsat is a term used in speculative astrophysics and in spacefaring fiction to describe a class of life-energy reservoirs associated with stars. The word is formed from Estonian elements elus (life) and täht (star), with the plural suffix -sat.

Description: Elutähtsat are described as luminescent or crystalline structures found in certain stellar environments. They are said to store energy in a biotic or bio-compatible form and can exchange energy with living systems, acting as a bridge between astrophysical and biological processes. In fictional settings, they may serve as carriers of genetic memory or ecological potential.

Formation and properties: Theoretical models place elutähtsat at the intersection of magnetohydrodynamics and prebiotic chemistry within protoplanetary disks or in remnants around evolved stars. Reported properties include slow energy release, resilience to high radiation, and distinctive infrared or spectroscopic signatures associated with complex organic compounds. They are often depicted as self-organizing, gravity-bound aggregates that can migrate through nebulae.

Occurrence and use: In worldbuilding contexts, elutähtsat explain how life-bearing systems arise in distant star regions or persist during interstellar travel. Researchers in-universe may study them to understand energy budgeting for biospheres, planetary colonization, and the origin of life. Some works treat elutähtsat as a conserved cosmic resource or as a marker of habitable epochs in a galaxy.
