Strong whistler mode waves observed in the vicinity of Jupiter’s moons
Nature Communications, 2018 Observations of Jupiter’s magnetosphere provide opportunities to understand how magnetic fields interact with particles. Here, the authors report that the chorus wave power is increased in the vicinity of Europa and Ganymede. The generated waves are able

The dynamics of the de Sitter resonance
, 2017 We study the dynamics of the de Sitter resonance, namely the stable equilibrium configuration of the first three Galilean satellites. We clarify the relation between this family of configurations and the more general Laplace resonant states.

Seismic wave propagation in icy ocean worlds
, 2017 Seismology was developed on Earth and shaped our model of the Earth's interior over the 20th century. With the exception of the Philae lander, all in situ extraterrestrial seismological effort to date was limited to other terrestrial planets. All have in

Europa, Another Water Moon? [PDF]
, 1999 Comparing Europa to Earth's size and oceans, this resource tells the story of the Galileo spacecraft's exploration of Europa in the late 1990's, and explains why scientists believe there may be an ocean of water underneath Europa's icy crust. Educational

Impact-induced Contamination of Ganymede’s Deep Ice Shell
The Planetary Science JournalJuno flew by Ganymede in 2021 June and measured the microwave brightness temperatures of the ice shell at six frequencies from 0.6–22 GHz. Based on the increasing brightness temperature with wavelength, S. Brown et al.

Planet Mass Function around M Stars at 1–10 au: A Plethora of Sub-Earth Mass Objects
The Astrophysical JournalSmall planets (≲1 M _⊕ ) at intermediate orbital distances (∼1 au) represent an uncharted territory in exoplanetary science. The upcoming microlensing survey by the Nancy Grace Roman Space Telescope will be sensitive to objects as light as Ganymede and ...

Resonant Plasma Acceleration at Jupiter Driven by Satellite‐Magnetosphere Interactions
Geophysical Research LettersThe Juno spacecraft had previously observed intense high frequency wave emission, broadband electron and energetic proton energy distributions within magnetic flux tubes connected to Io, Europa, Ganymede, and their wakes.

A Passive Probe for Subsurface Oceans and Liquid Water in Jupiter's Icy Moons
, 2014 We describe an interferometric reflectometer method for passive detection of subsurface oceans and liquid water in Jovian icy moons using Jupiter's decametric radio emission (DAM).

A Billion-Year Facelift and Cleaner Air
The Scientific World Journal, 2001 Science leads the first (or is it second?) year of the millennium with a story about a facelift for Jupiter’s moon, Ganymede. Nature leads with a story about new regulations on diesel-powered vehicles in the U.S.
