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.

Thermal Escape of Atomic Hydrogen on Mars: A Comprehensive View With a General Circulation Model
Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.Abstract Mars loses water mainly through the photodissociation of water vapor, followed by the thermal escape of light hydrogen atoms. Observations have revealed large seasonal variations in hydrogen concentration in the upper thermosphere, peaking during southern summers and intensifying during dust storms.

Investigating Potential Benefits of Future Sub‐L1 Missions With STEREO‐A
Space Weather, Volume 24, Issue 6, June 2026.Abstract We present the first statistical study of geomagnetic storm forecasting using in situ data from the STEREO‐A spacecraft as a sub‐L1 monitor. Between November 2022 and June 2024, STEREO‐A crossed the Sun–Earth line, covering longitudinal and radial separations of ±15° $\pm 15{}^{\circ}$ from the Sun–Earth line and 0.01–0.06 au from Earth.

Magnetic Rope Is an Electron Selector: Discovery in Space and Conceptual Application to Medicine
Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.Abstract Magnetic rope is a helical structure existing ubiquitously in astrophysical and space plasmas. Such structure has been conventionally known to accelerate electrons, convert energy, and play key roles in driving solar eruptions. Here, in contrast to the conventional concept, we report that the magnetic rope can divert electrons efficiently in ...

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.Abstract Nitric oxide (NO) radiative cooling governs much of the energy budget in the Earth's lower thermosphere and damps out temperature perturbations. The radiative relaxation time (RRT), the timescale that defines how efficiently infrared radiation damps out the perturbations to the thermal structure to 1/e of the perturbation's initial value, is ...

Wilson's Atmospheric Electron Accelerator: A Centennial Perspective
Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.Abstract As of the time of writing this letter, we mark the centennial of Wilson's runaway electrons proposed in 1925. Owing to instrumentation limitations, Wilson and his students could not detect the particles anticipated by theory Chilingarian et al. (2025, https://doi.org/10.1029/2024jd042350).

Ediacara Obscura: Unveiling Hidden Magnetisations in the Fen Complex, Southern Norway
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.Abstract Paleomagnetic directions found in Ediacaran (635–539 Ma) rocks are widely dispersed, which has led to conflicting hypotheses about tectonic regimes and geomagnetic field behavior during this period, and raised doubts about the fidelity of the paleomagnetic record.

Magnetic flares in the protoplanetary nebula and the origin of meteorite chondrules
, 1987 This study proposes and analyzes a model for the chondrule forming heating events based on magnetohydrodynamic flares in the corona of the protoplanetary nebula which precipitate energy in the form of energetic plasma along magnetic field lines down ...
