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 […]

Characterizing Deposits Emplaced By Cryovolcanic Plumes On Europa
In the absence of direct observations of Europa’s particle plumes, deposits left behind during eruptive events would provide the best evidence for recent geological activity, and would serve as indicators […]

Water Vapor Confirmed On Europa
Forty years ago, a Voyager spacecraft snapped the first closeup images of Europa, one of Jupiter’s 79 moons. These revealed brownish cracks slicing the moon’s icy surface, which give Europa […]
