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.

Predictions of Auroral Electron Precipitation and Joule Heating at Uranus

Geophysical Research Letters
The precipitation of electrons and Joule heating are key processes through which energy is transferred from Uranus' magnetosphere to its upper atmosphere. These processes drive atmospheric ionization, thermospheric heating, and auroral emission at Uranus.

Evaluation of the Canadian Regional Climate Model in Simulating Extratropical Cyclones Over Northeastern North America

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 18, 28 September 2026.
Abstract The ability of convection‐permitting regional climate models to realistically simulate extratropical cyclones (ETCs) and associated near‐surface wind speeds and precipitation remains poorly documented. This study provides the first comprehensive evaluation of the sixth version of the Canadian regional climate model (CRCM) for this purpose over

Contrasting C/O ratios in Uranus and Neptune from disequilibrium chemistry: A clue to distinct evolutionary pathways?

Astronomy & Astrophysics
Context. The formation of Uranus and Neptune remains poorly constrained, largely due to poorly known deep elemental abundances. Carbon monoxide (CO), a disequilibrium species in the upper troposphere, provides an indirect constraint on the deep oxygen ...

Investigating Galactic Cosmic Ray Ionization’s Contribution to Aerosol Formation on Neptune and a Potential Link to the Relationship Between Brightness and Solar Activity

Journal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.
Abstract In this work we investigate how ionization from Galactic Cosmic Rays (GCRs) can affect aerosol nucleation on Neptune and discuss potential implications for the observed brightness variations that appear to follow the solar cycle. We calculate the planetary vertical cutoff rigidity for Neptune based on the O8 ${\mathrm{O}}_{8}$ magnetic field ...

The Upper Atmosphere of Uranus from Stellar Occultations. II. Revised Temperatures in the Upper Stratosphere and Lower Thermosphere

The Planetary Science Journal
Measurements made by Voyager 2 during its flyby of Uranus in 1986 found warm stratospheric and hot thermospheric temperatures that cannot be explained by solar energy alone.

Uranus's Highly Nonaxisymmetric Magnetopause and Its Impact on Magnetic Reconnection

Journal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract Mass and energy fluxes from the solar wind can access a planet's magnetosphere through dayside magnetic reconnection. The plasma and magnetic field conditions on either side of the magnetopause determine whether reconnection is suppressed. However, magnetosheath conditions are sensitive to the shape of the magnetopause, and deviations from ...

Reassessing planetary composition: Evidence of rock-dominated envelopes in Uranus and Neptune

Astronomy & Astrophysics
Although Uranus and Neptune are commonly classified as ice giants, their exact compositions remain poorly constrained. Recent studies of outer Solar System bodies challenge the traditional view that these planets are primarily ice-dominated, suggesting ...

Detecting an Ocean Inside Callisto With Geodetic Measurements From Europa Clipper and Juice

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Determining whether Callisto hosts a subsurface ocean, and the implications for material and energy transport through its hydrosphere, is of high interest to NASA's Europa Clipper and ESA's Juice missions. A recent reanalysis of Galileo magnetometer data strengthens the ocean hypothesis, but definitive confirmation awaits new measurements.
