We present mid-infrared SOFIA/EXES spectroscopy of Europa, seeking direct evidence of the presence of water vapor arising from plumes venting from the surface of Europa. We place quantitatively useful upper […]

ALMA Maps The Temperature of Europa
Jupiter’s icy moon Europa has a chaotic surface terrain that is fractured and cracked, suggesting a long-standing history of geologic activity. A new series of four images of Europa taken […]

Europa Plume Sites Lack Expected Heat Signatures
The study of two potential plume sites on Jupiter’s moon Europa has shown a lack of expected hotspot signatures, unlike Enceladus where plumes have a very clear and obvious temperature […]

Condition For The Deflection of Vertical Cracks at Dissimilar Ice Interfaces On Europa
The surface of Europa contains many quasi-circular morphologies called lenticulae. Although the formation mechanism of lenticulae is not understood, sill intrusion from the subsurface ocean is one promising hypothesis. However, […]

ALMA Thermal Observations of Europa
We present four daytime thermal images of Europa taken with the Atacama Large Millimeter Array. Together, these images comprise the first spatially resolved thermal dataset with complete coverage of Europa’s […]

Radiation Maps of Jupiter’s Moon Europa: Key to Future Missions
New comprehensive mapping of the radiation pummeling Jupiter’s icy moon Europa reveals where scientists should look — and how deep they’ll have to go — when searching for signs of […]

Old Data Reveal New Evidence of Europa Plumes
Scientists re-examining data from an old mission bring new insights to the tantalizing question of whether Jupiter’s moon Europa has the ingredients to support life. The data provide independent evidence […]

The Origin and Fate of O2 in Europa's Ice: An Atmospheric Perspective
The early prediction and subsequent detection of an O2 atmosphere on Europa, coupled with the discovery that Europa has an ocean under its ice mantle, has made this moon a […]

Dusk Over Dawn O2 Asymmetry in Europa's Near-Surface Atmosphere
The evolution of Europa’s water-product exosphere over its 85-hour day, based on current models, has not been shown to exhibit any diurnal asymmetries. Here we simulate Europa’s exosphere using a […]

Model Based on Hydrothermal Sources And The Possibility of Life on Europa
Jupiter’s icy moon Europa is a major target of astrobiology research in light of the possibility that it offers a habitable environment in the Solar System. Under its ice crust, […]
