Galileo NIMS archival data reveal first ammonia-bearing compounds on Europa
Reanalysis of Galileo NIMS archival data has revealed the first spectral evidence of ammonia-bearing compounds on Europa's surface, concentrated in fracture regions. The finding implies altered ocean chemistry and recent subsurface-to-surface exchange, reshaping target selection and science goals for upcoming missions to assess habitability.
