On the Possibility of Melting Water Ice During the Recent Past of Mars: Implications for the Formation of Gullies

Journal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract The formation of gullies on Mars has often been attributed to the melting of (sub)surface water ice. However, melting‐based hypotheses generally overlook key processes: (a) sublimation cooling by latent heat absorption, (b) the non‐stability of ice where melting conditions can be reached, and (c) the particular microclimates of gullied slopes.

Behavior of Evaporation Ducts in Stable and Unstable Surface Layers

Radio Science, Volume 61, Issue 2, February 2026.
Abstract The atmospheric surface layer over the ocean has a strong impact on electromagnetic (EM) wave propagation in the lowest 100 m of the atmosphere. Due to surface evaporation, a strong vertical gradient in water vapor forms in this layer, resulting in an evaporation duct which may greatly increase detection ranges for sensors and targets within ...

Six‐Component Electromagnetic Wave Measurements of Sprite‐Associated Lightning

Radio Science, Volume 61, Issue 2, February 2026.
Abstract Low frequency electromagnetic waves emitted by sprite‐producing lightning are normally measured using vertical electric fields or horizontal magnetic fields. Here we report for the first time the simultaneous measurement of electromagnetic waves from sprite‐producing lightning in all six electromagnetic field components Ex,Ey,Ez,Hx,Hy,andHz ...

High-energy neutrino astrophysics

, 2018
High-energy (> 100 MeV) neutrino astrophysics enters an era of opportunity and discovery as the sensitivity of detectors approaches astrophysically relevant flux levels. We review the major challenges for this emerging field, among which the nature of dark matter, the origin of cosmic rays, and the physics of extreme objects such as active galactic ...

Addressing Known Challenges in Solar Flare Forecasting I: Limb‐Flare Prediction With a 4π Full‐Heliosphere Framework

Space Weather, Volume 24, Issue 2, February 2026.
Abstract A demonstrated failure mode for operational solar flare forecasting is the inability to forecast flares that occur near, or just beyond, the solar limb. To address this shortcoming, we develop a “4π $4{\uppi }$” full‐heliosphere event forecasting framework and evaluate its statistical classification ability against this specific challenge.
