Condensed O₂ on Europa and Callisto (original) (raw)

NASA/ADS

Abstract

High signal-to-noise ratio spectra of Europa and Callisto's trailing side show a 0.3% deep 5771 Å absorption band due to condensed O2 at the same wavelength as a stronger band previously identified on Ganymede. Excellent longitudinal coverage for Europa shows that unlike Ganymede, where the band is much stronger on the trailing side, Europa shows no significant longitudinal variation in the O2 band strength.
