Differentiating Plumes and Local Torus Segments of Enceladus

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract Enceladus's south polar plumes and their surrounding torus segments (local plasma regions formed by plume material diffusion) are key to understanding its magnetospheric interaction; however, clear observational criteria to distinguish them remain lacking.

The Influence of the Stretch of Mini‐Magnetospheres Formed by Crustal Fields on the Martian Bow Shock Location

Geophysical Research Letters
Mars lacks an intrinsic dipolar magnetic field but possesses strong crustal magnetic fields scattered across its surface. There has been an ongoing debate about how these crustal fields influence the bow shock, the outermost plasma boundary of the ...

Potential of Soils Natural Sorbents for Environmental Decontamination From 137Cs

Land Degradation &Development, Volume 37, Issue 2, Page 779-789, 30 January 2026.
ABSTRACT This study addresses the existing research gap concerning the lack of integrated data on the role of in situ soil components in the long‐term fixation of 137Cs under natural, protected, and non‐agricultural conditions. The contamination of ecosystems by radioactive isotopes, particularly 137Cs, represents a considerable environmental hazard ...

On the Energy Source of Green Emissions in Ghost

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract The understanding on the formation mechanism of ghosts as a new category of transient luminous events and favorable conditions for their occurrence is limited. In this work, we examined six ground‐based observations of ghost events captured by digital SLR cameras.

Computer simulations of cosmic-ray diffusion near supernova remnant shock waves [PDF]

A plasma simulation model was used to study the resonant interactions between streaming cosmic-ray ions and a self-consistent spectrum of Alfven waves, such as might exist in the interstellar medium upstream of a supernova remnant shock wave.

Whipped and Mixed Warm Clouds in the Deep Sea

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Turbulence is indispensable to redistribute nutrients for all life forms larger than microbial, on land and in the ocean. Yet, the development of deep‐sea turbulence was not studied in three dimensions to date. As a disproportionate laboratory, an array of nearly 3,000 high‐resolution temperature sensors had been installed for three years on ...

Predicting the arrival times of solar particles [PDF]

A procedure has been developed to generate a computerized time-intensity profile of the solar proton intensity expected at the earth after the occurrence of a significant solar flare on the sun.

Testing the proposed link between cosmic rays and cloud cover

, 2008
A decrease in the globally averaged low level cloud cover, deduced from the ISCCP infra red data, as the cosmic ray intensity decreased during the solar cycle 22 was observed by two groups.

Direct Observational Evidence of the Mesoscale Gravity Wave Modulations on Low‐Latitude Sporadic E Layer

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Sporadic E (Es) layer plays essential role in ionosphere‐atmosphere coupling. Theoretical simulations show that the atmospheric gravity waves (GWs) in the lower thermosphere are the main modulatory source on Es dynamics at small spatial scales and short periods.

Spatial Distributions of Energetic Electrons and Energetic Ions in the Tail Reconnection Region: Cluster Observations and PIC Simulations

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract High‐energy particles are prevalent in space, and magnetic reconnection is one of the physical processes responsible for their generation. The heating and acceleration of ions and electrons typically occur respectively in the ion diffusion region and the electron diffusion region.
