Dawn–Dusk Asymmetry of the Io Plasma Torus Derived from Io’s Auroral Footprints Observed by Juno-UVS

The Planetary Science Journal
The Io plasma torus (IPT) is a dense plasma cloud that corotates around Jupiter near Io’s orbit. A dawn-to-dusk electric field shifts the IPT dawnward.

Characteristic Responses of Particles and Plasma Waves During Interchange Events at Jupiter Using Juno Observations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract Interchange instability plays a critical role in driving mass and plasma transport within Jupiter's inner and middle magnetospheres. In this study, we present a superposed epoch analysis of 160 interchange events to quantify their characteristic signatures of magnetic fields, particles, and plasma waves using Juno data from 2016 to 2024 ...

CCD positions for eight Jovian irregular satellites

, 2006
The astrometric positions of eight irregular Jovian satellites are given for the oppositions of the planet from 1995 to 1999. These positions were measured on 204 CCD frames obtained at the Cassegrain focus of a 1.6 m reflector.

JWST Reveals Varied Origins between Jupiter’s Irregular Satellites

The Planetary Science Journal
We report JWST NIRSpec (0.7–5.1 μ m) observations of eight Jovian irregular satellites across five orbital groups. We detect variation in the phyllosilicate content of the three largest members of the Himalia collisional family (Himalia, D  ∼ 140 km ...

A Mechanism for the Generation of Enhanced Fluxes at Discrete Energies on the Wakes of the Galilean Moons

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract In this study, we propose a new mechanism to explain the observed particle flux at discrete energies in the flux tubes connecting to the wakes of the Galilean moons, first reported by Sarkango et al. (2024, https://doi.org/10.1029/2023gl107431) and referred to as “banded flux.” We demonstrate the proposed mechanism using test particle ...

A CCD comparison of outer Jovian satellites and Trojan asteroids [PDF]

, 1991
The eight small outer Jovian satellites are not as well known as the brighter, more illustrious Galilean satellites. They are divided into two groups, each containing four satellites; the inner group travels in prograde orbits while the outer group ...

Plasma Properties at the Orbits of Ganymede and Callisto: Survey of Juno Data

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract The space environment around the Galilean moons is important for understanding the interaction of the magnetospheric plasma with their magnetosphere (in the singular case of Ganymede), their atmospheres and surfaces. Juno's orbital evolution brought the spacecraft close to the orbits of Ganymede and Callisto on multiple occasions over several ...

Europa’s Sodium and Potassium Exosphere during Juno’s Flyby

The Planetary Science Journal
Jupiter’s icy moon Europa is enveloped in gaseous sodium and potassium that resonantly scatter sunlight as optical emission lines. The High Resolution Echelle Spectrograph on the Keck I telescope has spatially mapped these alkalis contemporaneously with ...

Type‐III Solar Radio Bursts at Mars: A 16.5‐Year Catalog From Mars Express‐MARSIS at 0.1–5.5 MHz

Space Weather, Volume 24, Issue 10, October 2026.
Abstract The most intense radio feature in the Solar System are the solar Type‐III radio bursts, which are associated with electron beams that propagate along open magnetic field lines. Although solar radio bursts have been studied since the 1940s, observations remain mainly restricted within 1 AU.

Surface Changes on Io Observed by Large Binocular Telescope/SHARK in Early 2025

The Planetary Science Journal
High spatial resolution images of the volcanic moon Io at visible and near-infrared wavelengths were obtained by the SHARK-VIS and SHARK-NIR instruments on the Large Binocular Telescope on UT 2025 February 18 and 23.
