Phosphine in Brown Dwarf Atmospheres: Biosignature Clues
Introduction: Phosphine and the hunt for life beyond Earth Scientists seeking life beyond our planet often focus on biosignatures—molecules that hint at biological processes. Phosphine, a gas produced by anaerobic microbes on Earth, has long been proposed as a potential marker of life. Yet before any molecule can be treated as a true biosignature, researchers…

Phosphine Detected in Brown Dwarf Atmosphere
Biosignatures, phosphine, and the brown-dwarf twist In the search for life beyond Earth, scientists look for biosignatures—molecules whose presence could signal biology. Phosphine is one such candidate because on our planet it is produced primarily by anaerobic organisms and is rarely formed through abiotic processes in oxygen-rich environments. Yet before scientists declare any molecule a…
