Atmospheric Ion‐Neutral Coupling as a Potential Driver for Saturn's Magnetospheric Antisunward Electric Field

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Saturn's inner magnetosphere contains a weak antisunward electric field that has influenced a wide array of different aspects of the magnetospheric conditions in that region. Previously, these currents have been explained as being caused by magnetospheric drivers.

Global Morphology of Chorus Waves in the Outer Radiation Belt and the Effect of Geomagnetic Activity and fpe ${f}_{pe}$/fce ${f}_{ce}$

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract Whistler‐mode chorus waves play a key role in driving radiation belt dynamics by enabling both acceleration of electrons to relativistic energies as well as their loss into the atmosphere via pitch‐angle scattering. The ratio between the electron plasma frequency (fpe ${f}_{pe}$) and the electron gyrofrequency (fce ${f}_{ce}$) significantly ...

Current Events at Saturn: Ring–Planet Electromagnetic Coupling

The Planetary Science Journal
This study presents a synthesized analysis of in situ and ground-based observations to investigate electromagnetic coupling between Saturn and its rings. During the Cassini Grand Finale, the magnetometer detected gradients in the azimuthal magnetic field

Saturn's Exploration Beyond Cassini-Huygens [PDF]

, 2009
For its beautiful rings, active atmosphere and mysterious magnetic field, Saturn is a fascinating planet. It also holds some of the keys to understanding the formation of our Solar System and the evolution of giant planets in general.

Reconstructing Magnetotail Reconnection Events Using Data Mining is Feasible and Repeatable

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 1, February 2026.
Abstract Recently, Stephens et al. (2023), https://doi.org/10.1029/2022ja031066 utilized a data mining (DM) algorithm, applied to 26 years of magnetospheric magnetometer observations coupled with a flexible formulation of the magnetospheric magnetic field, to reconstruct the global configuration of the magnetotail when the Magnetospheric MultiScale ...

Low Frequency Oscillation Observed in the Ionosphere Around the Substorm Onsets

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Three substorm events in which Defense Meteorological Satellite Program (DMSP) spacecraft are geomagnetically co‐located with substorm onset locations in IMAGE far ultraviolet auroral images are analyzed. A Hilbert‐Huang Transform is used to decompose the DMSP B⊥ ${B}_{\perp }$ in the ionosphere to its intrinsic mode functions. A dominant mode

Ambipolar Electric Field, Photoelectrons, and their Role in Atmospheric Escape From Hot-jupiters [PDF]

, 2012
Atmospheric mass-loss from Hot-jupiters can be large due to the close proximity of these planets to their host star and the strong radiation the planetary atmosphere receives.

Multipoint Observations of a SLAMS Evolution and Its Merger With Whistler Waves

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract We report multipoint observations of a merger between a Short Large‐Amplitude Magnetic Structure (SLAMS) and 1‐Hz whistler wave packets upstream of Earth's quasi‐parallel bow shock. Using high‐resolution data from the Magnetospheric Multiscale (MMS) mission in a string‐of‐pearls configuration, we track the SLAMS as it evolves, exhibiting ...

Plasma Conditions Govern the Reversible Transition Between STEVE and Picket Fence Emissions

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract On 6 May 2018, a remarkable subauroral optical event exhibiting three phases of evolution (Strong Thermal Emission Velocity Enhancement [STEVE] → Picket Fence → STEVE) and co‐occurrence with a stable auroral red arc was observed over Alberta, Canada.
