    JWST Reveals Spectral Tracers of Recent Surface Modification on Europa by Richard J. Cartwright, Charles A. Hibbitts, Bryan J. Holler, Ujjwal Raut, Tom A. Nordheim, Marc Neveu, Silvia Protopapa, Christopher R. Glein, Erin J. Leonard, Lorenz Roth, Chloe B. Beddingfield, Geronimo L. Villanueva

    Published 2025-01-01
    “…These results support the hypothesis that H _2 O ice in Europa’s regolith is vertically stratified, with amorphous ice grains dominating its exposed surface, except in Tara and Powys Regiones. We also find that a previously detected 4.38 μ m ^13 CO _2 feature is present almost exclusively at southern latitudes in Tara and Powys Regiones, likely derived from an internal source of carbon-bearing material.…”
