Interactions of Sublimated Frost With Volcanic Plumes: Modeling Io's SO2 Atmosphere Using the DSMC Method

Journal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.
Abstract Io's tenuous atmosphere consists primarily of sulfur dioxide (SO2 ${\text{SO}}_{2}$) with observed column densities of approximately 1016−1017 $1{0}^{16}-1{0}^{17}$ cm−2 ${\text{cm}}^{-2}$. However, it remains uncertain whether the sublimation of SO2 ${\text{SO}}_{2}$ surface frost or volcanic outgassing is the primary source of the SO2 ...

Mapping of the Ganymede surface reflectance from Juno/UVS data

Astronomy & Astrophysics
Context. Ganymede is the only moon in the Solar System with an intrinsic magnetic field that actively interacts with the Jupiter magnetosphere. This precipitates energetic electrons that generate ultraviolet (UV) auroral emission. Aims. In sunlit auroral

Capturing Secondary Kinetic Instabilities in Three‐Dimensional Dayside Reconnection Using an Improved Gradient‐Based Closure

Journal of Geophysical Research: Space Physics, Volume 131, Issue 7, July 2026.
Abstract Magnetic reconnection is a highly dynamic process that excites a wide variety of kinetic waves and instabilities. Transverse current sheet instabilities such as the lower‐hybrid drift and secondary drift‐kink instabilities in particular have been shown by kinetic simulations to modify the reconnection and introduce significant turbulence and ...

Backscattering of Ions Impacting Ganymede’s Surface as a Source for Energetic Neutral Atoms

The Astrophysical Journal Letters
Jupiter’s largest moon Ganymede has its own intrinsic magnetic field, which forms a magnetosphere that is embedded within Jupiter’s corotating magnetospheric plasma.

Mercury's Alfvén Wing Current System Under Sub‐Alfvénic Solar Wind Conditions: Insights From Global MHD Simulations

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Mercury's proximity to the Sun results in the lowest average Alfvénic Mach number in the upstream solar wind compared to any other planet. Under extreme conditions, the upstream Alfvén speed can exceed the solar wind speed, resulting in a sub‐Alfvénic interaction in which standing Alfvén wings form.

Ganymede’s Tenuous Atmosphere

Ganymede possesses a tenuous water-based atmosphere, thought to be produced by the solar and Jovian plasma irradiation of its icy surface. Observational evidence for Ganymede's atmosphere is provided by far-ultraviolet (FUV) emission from the atomic oxygen (O) and hydrogen (H) constituents.

Mid‐Infrared Absorption Coefficients of Human Skin Stratum Corneum

Advanced Photonics Research, Volume 7, Issue 6, June 2026.
This work reports the first quantitative determination of mid‐infrared absorption coefficients for the human stratum corneum. By utilizing transmission infrared spectroscopy across varying hydration levels, the study establishes a fundamental dataset for understanding and rigorous modeling of light–skin interaction.

New Results From Galileo's First Flyby of Ganymede: Reconnection‐Driven Flows at the Low‐Latitude Magnetopause Boundary, Crossing the Cusp, and Icy Ionospheric Escape

Geophysical Research Letters, 2018
On 27 June 1996, the NASA Galileo spacecraft made humanity's first flyby of Jupiter's largest moon, Ganymede, discovering that it is the only moon known to possess an internally generated magnetic field. Resurrecting the original Galileo Plasma Subsystem

Species‐Specific Vulnerability of Northern Red Sea Mesophotic Corals to Accelerated Warming

Global Change Biology Communications, Volume 1, Issue 2, June 2026.
Mesophotic reefs are often considered climate refuges, yet experimental thermal‐stress reveals species‐dependent vulnerability. Skeletal optics, energy reserves, and light environment determine bleaching severity. A depth‐generalist coral resisted stress while the mesophotic specialist bleached severely.

UVS Observations of Ganymede's Aurora During Juno Orbits 34 and 35

Geophysical Research Letters, 2022
On 7 June 2021, Juno‐UVS mapped Ganymede's auroral emissions near a closest approach altitude of 1,046 km. The high spatial resolution map exhibits bright, 200–1,000 R, oxygen emissions organized into northern and southern auroral ovals.
