Uranus' Long‐Term Thermospheric Cooling Is Unlikely to Be Primarily Driven by the Solar Wind

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract Over the last 40 yrs, Uranus' thermospheric temperature has decreased by ∼8 K/yr. Here we show that this is less likely to be driven by solar wind kinetic power than previously thought. We determine that the solar wind kinetic power at Uranus has been increasing since the start of solar cycle 24 in 2009, while Uranus's thermospheric ...

The role of the dynamic terrestrial exosphere in the storm-time ring current decay

Frontiers in Astronomy and Space Sciences
The charge exchange interaction between exospheric hydrogen (H) atoms and energetic ions in the terrestrial ring current is a crucial mechanism for dissipating global magnetospheric energy, especially during the recovery phase of geomagnetic storms ...

Energetic Electron Spectra at Low Altitudes: Transition From the Plasma Sheet to the Outer Radiation Belt

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract Low‐altitude measurements of energetic electron fluxes offer insight into the dynamics of the radiation belts and plasma sheet. However, distinguishing between key magnetospheric regions–such as inner belt, slot region, outer belt, and plasma sheet–based on low‐altitude data remains challenging, particularly for missions lacking pitch‐angle ...

Magnetopause Location and Solar Wind Turbulence Level During FDs and Their Impacts on the Global Electric Circuit

Space Weather
During Forbush decreases (FDs), the fluxes of high‐energy galactic cosmic rays (GCRs) are suppressed. As a consequence, the ionization profile of the atmosphere is affected and the global electric circuit system is perturbed.

Solar wind origin of terrestrial water

, 2011
The origin of the Earth water reserves during the evolution of the planet is one of the big miracles in geophysics. Common explanations are storage of water in the Earth mantle at a time when the crust had not yet formed and depositing of water by comets

Solar Energetic Particle Events During May 2024 Geomagnetic Superstorm

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract Three solar energetic particle (SEP) events originating from solar active region 13664 occurred on 10–16 May 2024, coinciding with a geomagnetic superstorm. Using data from the Geostationary Operational Environmental Satellites and Meteorological Operational satellite‐C, we investigate the energetic proton fluxes and east‐west flux ratios in ...

The Global Propagation of Hiss Waves Originating From Dynamic Plasmaspheric Plume

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract Hiss waves play a critical role in shaping Earth's radiation belts and mediating magnetosphere‐ionosphere energy transfer. Intense hiss emissions are frequently generated within dynamic plasmaspheric plumes through linear and nonlinear wave‐particle interactions.

Plasma Acceleration by Magnetic Tension Forces in the Martian Magnetotail: MAVEN Observations

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract The Martian magnetotail is a dynamic region where several processes contribute to plasma acceleration. Here, we analyze ∼5 ${\sim} 5$ years of Mars Atmosphere and Volatile EvolutioN (MAVEN) data to evaluate the role of magnetic tension forces in driving plasma acceleration within current sheets in the tail. Based on magnetic field measurements,
