Phosphine on Brown Dwarfs Challenges Life-Signature Claims
Phosphine and the hunt for alien life Phosphine, a molecule composed of one phosphorus atom and three hydrogen atoms, has long been touted as a potential beacon of life beyond Earth. On our planet, phosphine is produced mainly by biological activity or through industrial synthesis, making it a compelling, albeit controversial, biosignature. In recent years,…

Phosphine on a brown dwarf reshapes the life-sign biosignature debate
Phosphine on a brown dwarf: a surprising detection NASA’s James Webb Space Telescope (JWST) has detected phosphine in the atmosphere of Wolf 1130C, a brown dwarf often described as a “failed star.” The discovery, published in Science, challenges the idea that phosphine is a universal sign of life. Brown dwarfs sit between planets and stars:…
