NASA discovers phosphine on distant star, raising questions about ‘life signal’

NASA’s James Webb Space Telescope (JWST) has recently identified a molecule on a remote Brown Dwarf star that was previously considered a potential indicator of life. This molecule, phosphine, was found on a star, challenging its role as a biomarker of extraterrestrial life. The discovery has sparked discussions among scientists about the origins and implications of phosphine in space. Researchers are now questioning the reliability of phosphine as a definitive ‘life signal’ in the universe.
