The composition and structure of the Enceladus plume
The Cassini Ultraviolet Imaging Spectrograph (UVIS) observed an occultation of the Sun by the water vapor plume at the south polar region of Saturn's moon Enceladus. The Extreme Ultraviolet (EUV) spectrum is dominated by the spectral signature of H2O gas, with a nominal line-of-sight column density of 0.90 0.23 × 1016 cm-2 (upper limit of 1.0 × 1016 cm-2). The upper limit for N2 is 5 × 1013 cm-2, or <0.5% in the plume; the lack of N2 has significant implications for models of the geochemistry...[Show more]
