Endogenous CO2 ice mixture on the surface of Europa and no detection of plume activity

GL Villanueva, HB Hammel, SN Milam, S Faggi… - Science, 2023 - science.org
Jupiter's moon Europa has a subsurface ocean beneath an icy crust. Conditions within the
ocean are unknown, and it is unclear whether it is connected to the surface. We observed …

JWST molecular map** and characterization of Enceladus' water plume feeding its torus

GL Villanueva, HB Hammel, SN Milam, V Kofman… - Nature …, 2023 - nature.com
Enceladus is a prime target in the search for life in our Solar System, having an active plume
that is likely to be connected to a large liquid water sub-surface ocean. Using the sensitive …
