A JWST Study of CO2 on the Satellites of Saturn

The Planetary Science Journal
Solid state CO _2 has been detected throughout the outer solar system, even at temperatures where crystalline CO _2 is unstable, requiring that the CO _2 be trapped in a separate host material. The Saturnian satellites provide an ideal laboratory for the

Evolution of a Point Plume in a Rotating Unstratified Fluid Overlain by a Stratified Layer: Scaling and Implications for Icy Satellites

Journal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.
Abstract Plumes that rise through an unstratified layer and penetrate into an adjacent stably stratified layer are ubiquitous in geophysical and planetary environments, including the subsurface oceans of icy satellites such as Europa, Enceladus, and Titan. In this study, we investigate the evolution of such plumes from isolated buoyant sources, both in

The Potential for Organic Synthesis in the Ocean of Enceladus

The Astrophysical Journal
The Cassini spacecraft detected a soup of organics in the plume of Saturn’s moon Enceladus. Those compounds could provide building blocks for the potential emergence or sustenance of microbial life in Enceladus’ subsurface ocean. However, the sources and

Inter‐Orbit Variability of Jupiter's Current Sheet Morphology

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract The structure of Jupiter's magnetosphere reflects the combined effects of a strong intrinsic field and an extended hinged current sheet whose morphology varies with solar wind forcing. We present a study of Jupiter's magnetodisc that combines the UCL‐AGA magnetodisc code with Khurana's generalized, hinged current sheet models (1992/2022) to ...

Extensional tectonics of the Saturnian Satellites [PDF]

, 1985
The saturnian satellites were imaged by the Voyager spacecraft at sufficient resolutions to reveal landforms that indicate histories of extensional tectonics for several of these bodies.

Asymmetric Distribution of Electron Density near Enceladus: A Comparative Survey of Upstream and Downstream Cassini Flybys

The Astrophysical Journal
Enceladus is a key source of plasma and neutrals in Saturn’s magnetosphere through its active south polar plume, which drives complex dust–plasma interactions and modifies the local environment.

What Observations Would an Energetic Neutral Atom Imager Have Made During the Voyager 2 Flyby of Uranus?

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract We present large‐scale simulations of energetic neutral atom (ENA) emissions at Uranus from a spacecraft viewpoint. Models of magnetic field, extended hydrogen exosphere, moon‐sourced neutral tori, and proton radiation belt are implemented into a simulator to evaluate the production of ENAs for L $L$ = 1–15.

Retrograde Predominance of Small Saturnian Moons Reiterates a Recent Retrograde Collisional Disruption

The Planetary Science Journal
We report the discovery and careful orbital determination of 64 new irregular moons of Saturn found in images taken using the Canada–France–Hawaii Telescope from 2019 to 2021, bringing the total number of Saturnian irregulars to 122.

Soft X‐Ray Emission From Saturn's Magnetosheath II: Solar Wind Driving

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract Saturn's magnetosphere is dominated by Enceladus‐sourced neutrals, which spread throughout the system into the magnetosheath. The neutrals can charge exchange with highly charged solar wind ions, causing soft X‐ray emission (<2 ${< } 2$ keV) upon de‐excitation of the ion.

Onboard Science Instrument Autonomy for the Detection of Microscopy Biosignatures on the Ocean Worlds Life Surveyor

The Planetary Science Journal
The quest to find extraterrestrial life is a critical scientific endeavor with civilization-level implications. Icy moons in our solar system are promising targets for exploration because their liquid oceans make them potential habitats ...
