Water Transport from Enceladus to the Rings
The Planetary Science JournalEnceladus continuously ejects approximately 300 kg s ^−1 of water vapor from its south polar regions, forming an extensive neutral gas torus around Saturn.

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract During Galileo's closest (“E12”) flyby of Europa, a brief burst of wave activity was recorded by the plasma wave instrumentation, PWS. This was speculatively interpreted by Jia et al. (2018, https://doi.org/10.1038/s41550‐018‐0450‐z) as a 2,100 cm−3 spike in plasma densities from a water plume encounter. While the plasma instrument, PLS, could

Ocean stratification impedes particulate transport to the plumes of Enceladus
Communications Earth & EnvironmentWater-vapour plumes erupting from Enceladus’ south pole provide a window into the properties of its subsurface ocean, a prime target in the search for life. However, the extent to which plume material represents conditions at Enceladus’ depths is unclear,

Slantwise Convection and Heat Transport in Icy Moon Oceans
Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract Ocean heat transport on icy moons shapes the ice shell topography, a primary observable of these moons. Two key processes control the heat transport: baroclinic instability driven by surface buoyancy contrasts and convective instability driven by heating from the core.

Biological methane production under putative Enceladus-like conditions
Nature Communications, 2018 Many methanogenic archaea use H2 and CO2 to produce methane. Here, Taubner et al. show that Methanothermococcus okinawensis produces methane under conditions extrapolated for Saturn’s icy moon, Enceladus, and estimate that serpentinization may produce ...

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract In Saturn's magnetosphere, the inward transport of magnetic flux is largely carried by localized injection flux tubes filled with warm, tenuous plasma, although their inflow speeds and spatio‐temporal properties remain poorly constrained. Here, we propose that these flux tubes can modify electron microsignatures, the small‐scale, absorption ...

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract Saturn's inner magnetosphere contains a weak antisunward electric field that has influenced a wide array of different aspects of the magnetospheric conditions in that region. Previously, these currents have been explained as being caused by magnetospheric drivers.

Analysis of Ion Cyclotron Waves during Cassini’s Flybys of Enceladus
The Astrophysical JournalIon cyclotron waves (ICWs) are ubiquitous phenomena within Saturn’s magnetosphere, particularly in the vicinity of Enceladus. This study focuses on the Cassini spacecraft’s flyby data of Enceladus to investigate the spatial distribution and properties of

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
