JWST Reveals Surface Processes on Europa

This paper presents a novel data-driven analysis of JWST NIRSpec-IFU observations of Europa's leading hemisphere across three observing geometries, targeting nine spectral bands sensitive to water ice, radiolytic products, and volatiles. The study aims to understand the competing processes that shape Europa's surface: geological activity and bombardment by charged particles. Through spectral factorization, the authors isolate the dominant components of spectral variability and reconstruct their spatial distributions. The key finding is that CO2 enrichment extends beyond Tara Regio, covering multiple chaos units in a lens-like pattern. These CO2-enriched areas co-occur with anomalous ice-texture signatures. The authors suggest that enrichment in volatiles on Europa may reflect retention-favorable near-surface microphysics as well as emplacement, refining how they are interpreted in the context of surface-interior exchange. This has implications for interpreting the sources and supply rates of extant carbon-bearing species and, ultimately, for assessing Europa's habitability. The success of this analysis hinges on the quality of JWST data and the effectiveness of the spectral factorization techniques. The potential impact is significant, as it provides new insights into the surface processes on Europa and their implications for habitability.
