Bayesian Analysis Of Juno/JIRAM's NIR Observations Of Europa
Juno spacecraft’s spectrometer JIRAM recently observed the moon Europa in the 2-5 {\mu}m wavelength region. Here we present analysis of the average spectrum of a set of observations near 20°N […]

Researchers Model Source Of Eruption On Jupiter's Moon Europa
On Jupiter’s icy moon Europa, powerful eruptions may spew into space, raising questions among hopeful astrobiologists on Earth: What would blast out from miles-high plumes? Could they contain signs of […]

Constraints On Effusive Cryovolcanic Eruptions On Europa Using Topography From Galileo Images
Images of Europa’s surface taken by the Galileo Solid State Imager (SSI) show smooth features measuring a few kilometers, potentially resulting from eruptions of low-viscosity material. We estimate the volumes […]

Regional Study of Europa's Photometry
The surface of Europa is geologically young and shows signs of current activity. Studying it from a photometric point of view gives us insight on its physical state. We used […]

The Ocean Inside Europa Could Be Habitable
A new model from NASA scientists supports the theory that the interior ocean in Jupiter’s moon Europa would be able to sustain life. In addition they have calculated that this […]

Europa's Dynamic Ocean: Taylor Columns, Eddies, Convection, Ice Melting And Salinity
The deep ocean (~100 km) of Europa, Jupiter’s moon, is covered by a thick (tens of km) icy shell, and is one of the most probable places in the solar […]

New Evidence Of Watery Plumes On Jupiter's Moon Europa
Jupiter’s moon Europa is a fascinating world. On its surface, the moon appears to be scratched and scored with reddish-brown scars, which rake across the surface in a crisscrossing pattern. […]

Newly Reprocessed Images of Europa Show 'Chaos Terrain' in Crisp Detail
The surface of Jupiter’s moon Europa features a widely varied landscape, including ridges, bands, small rounded domes and disrupted spaces that geologists call “chaos terrain.” Three newly reprocessed images, taken […]

Europa's Hemispheric Color Dichotomy as a Constraint on Non-synchronous Rotation
Europa’s surface reflectance exhibits a pronounced hemispheric dichotomy, which is hypothesized to form due to enhanced irradiation of the trailing hemisphere by energetic particles entrained in the jovian magnetosphere. We […]
