New Global Map of Io’s Volcanic Thermal Emission and Discovery of Hemispherical Dichotomies

The Planetary Science Journal
By combining multiple spacecraft and telescope data sets, the first fully global volcanic heat flow map of Io has been created, incorporating data down to spatial resolutions of ∼10 km pixel ^−1 in Io’s polar regions.

Ice chemistry on the Galilean satellites [PDF]

Journal of Geophysical Research: Planets, 1998
Jupiter's icy satellites Europa, Ganymede, and Callisto are subject to energy fluxes from electrons, photons, and magnetospheric plasma ion bombardment. As water ice and CO2 ice are thought to be present on their surfaces, the radiolysis of these materials over time should produce more complicated CHO‐containing molecules. These may include CH3OH, H2CO,

Modeling Ganymede's Surface Charging in Preparation for the JUICE Mission

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract The European Space Agency's (ESA) JUICE mission (JUpiter ICy moons Explorer) is en route to the Jovian system to characterize Ganymede's subsurface ocean. Determining the ocean's conductivity and depth requires precise measurements of its induced magnetic field at the position of JUICE.

Hot Spot Detections and Volcanic Changes on Io during the Juno Epoch: Orbits PJ5 to PJ55

The Planetary Science Journal
We report volcanic changes on Io since the last Galileo (2002) and New Horizons (2007) flybys as observed by NASA’s Juno spacecraft, examining Io’s volcanism down to the local scale (200 K at 325 individual sites of volcanic activity has been generated ...

Not just gas: How solids-driven torques shaped the migration of the Galilean moons

Astronomy & Astrophysics
Context. A crucial aspect of formation models for the Galilean moons of Jupiter is that the objects survive rapid inward orbital migration. Aims. The primary aim of this study is to investigate the orbital migration of the Galilean moons by incorporating

Motional Induction in Ganymede's Ocean

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract We investigate the magnetic signature of oceanic circulation in Ganymede's subsurface ocean using kinematic induction modeling. Our approach couples zonal jet flows from rotating thermal convection simulations with magnetic field models incorporating Ganymede's internal dynamo and external contributions from Jupiter.

Eclipses of the inner satellites of Jupiter observed in 2015

, 2016
During the 2014-2015 campaign of mutual events, we recorded ground-based photometric observations of eclipses of Amalthea (JV) and, for the first time, Thebe (JXIV) by the Galilean moons.

Europa is Embedded in Non‐Maxwellian, Anisotropic Electron Distributions

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract In September 2022, the Juno spacecraft flew by Europa, providing new insight into the electron pitch angle and energy distributions via the Jovian Auroral Distributions Experiment electron analyzers (JADE‐E). We fit these observations with two anisotropic kappa distributions (cold and hot), accounting for spacecraft potential, which we find to
