Abstract

Jupiter's moon Europa has a subsurface ocean, the chemistry of which is largely unknown. Carbon dioxide (CO₂) has previously been detected on the surface of Europa, but it was not possible to determine whether it originated from subsurface ocean chemistry, was delivered by impacts, or was produced on the surface by radiation processing of impact-delivered material. We mapped the distribution of CO₂ on Europa using observations obtained with the James Webb Space Telescope (JWST). We found a concentration of CO₂ within Tara Regio, a recently resurfaced terrain. This indicates that the CO₂ is derived from an internal carbon source. We propose that the CO₂ formed in the internal ocean, although we cannot rule out formation on the surface through radiolytic conversion of ocean-derived organics or carbonates.

• I **think** this means that Europa's oceans are carbonated, though we are currently working on experiments to see if that is true. Also you can read the non-paywalled verison here. arxiv.org/abs/2309. [bsky, 23 points, 3 comments]
