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 ...

Global Effects of Chorus and Hiss Waves on Trapped Energetic Electrons at Jupiter

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Unlike Earth, where whistler‐mode chorus is generally observed outside the plasmasphere and hiss is predominantly confined within it, Jupiter's magnetosphere frequently hosts both wave modes simultaneously. Using Juno observations, we present a global survey of whistler‐mode waves at Jupiter, demonstrating that both chorus and hiss are ...

Radio Pulse Power Distribution of Lightning in Jupiter's 2021–2022 Stealth Superstorms

AGU Advances, Volume 7, Issue 2, April 2026.
Abstract Surveys and observations of lightning on Jupiter prior to the NASA Juno mission used night‐side imaging approaches, and a common conclusion was that the optical energy was similar to the highest energy terrestrial lightning flashes, or superbolts.

Application of the MEGNO technique to the dynamics of Jovian irregular satellites

, 2009
We apply the MEGNO (Mean Exponential Growth of Nearby Orbits) technique to the dynamics of Jovian irregular satellites. We demonstrate the efficiency of applying the MEGNO indicator to generate a mapping of relevant phase-space regions occupied by ...

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 ...

The long-term dynamics of the Jovian irregular satellites [PDF]

Astronomy & Astrophysics, 2011
Context. The dynamical region of the Jovian irregular satellites presents an interesting web of resonances that are not yet fully understood. Of particular interest is the influence of the resonances on the stochasticity of the individual orbits of the satellites, as well as on the long-term chaotic diffusion of the different families of satellites ...

New Constraints on the Jovian Narrowband Radio Components From Juno/Waves Observations and 3D Geometrical Simulations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.
Abstract Measurements of Waves instrument onboard the Juno spacecraft suggest that narrowband kilometric radiation (nKOM; 20–141 kHz) and narrowband low‐frequency radiation (nLF; 5–70 kHz) are generated within the plasma near the Io plasma torus (IPT) in low‐latitude regions.

On the Insignificance of Photochemical Hydrocarbon Aerosols in the Atmospheres of Close-in Extrasolar Giant Planets [PDF]

, 2004
The close-in extrasolar giant planets (CEGPs) reside in irradiated environments much more intense than that of the giant planets in our solar system. The high UV irradiance strongly influences their photochemistry and the general current view believed ...

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.

Astrometry from mutual events of Jovian satellites in 1997 [PDF]

Astronomy & Astrophysics, 2003
Astrometric results of observations of the mutual events of the Galilean satellites of Jupiter of the PHEMU97 campaign by the Institut de Mecanique Celeste et de Calcul des Ephemerides are presented. These astrometric positions can be directly utilized in the construction of future ephemerides.
