Using the James Webb Space Telescope, scientists have detected phosphine gas in the atmosphere of the brown dwarf Wolf 1130C, about 54 light-years away. The finding suggests phosphine can form in extreme, non-biological environments, challenging its status as a potential biomarker and reshaping how scientists search for alien life.Using the James Webb Space Telescope, scientists have detected phosphine gas in the atmosphere of the brown dwarf Wolf 1130C, about 54 light-years away.
