Reported plume detections at Jupiter’s moon Europa are exciting but uncertain. They could be from active ice volcanic eruptions like those on Saturn’s moon Enceladus. We ask the question, could these detections also be explained by meteoroid impacts spewing water ice and vapor upward? The number of impacts occurring right now on Europa is not well known, and the number of plume detections could easily fall within the wide range of estimated impact rates.


As a start to figuring out whether the observations are from internal or external sources, we will present constraints on how often impacts are currently happening at Europa, and how difficult it would be to observe them, both from Earth-based telescopes and future missions such as NASA Europa Clipper and ESA Juice.
