Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract During Galileo's closest (“E12”) flyby of Europa, a brief burst of wave activity was recorded by the plasma wave instrumentation, PWS. This was speculatively interpreted by Jia et al. (2018, https://doi.org/10.1038/s41550‐018‐0450‐z) as a 2,100 cm−3 spike in plasma densities from a water plume encounter. While the plasma instrument, PLS, could

Spectral Properties and Energy Injection in Mercury's Magnetotail Current Sheet
Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract Mercury's magnetotail hosts a thin and highly dynamic current sheet (CS), where magnetic reconnection and strong fluctuations frequently occur. Here, we statistically analyze magnetic field power spectra across 370 magnetotail CSs observed by MESSENGER.

How Unusual Was the Paleocene‐Eocene Thermal Maximum?
Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract The Paleocene‐Eocene Thermal Maximum (PETM) was an extreme fluctuation of Earth's climate and a potential analog for future unmitigated anthropogenic climate change, but whose cause is debated. We show that fluctuations in Cenozoic benthic foraminiferal δ13 ${\delta }^{13}$C and δ18 ${\delta }^{18}$O follow a Laplace distribution. We present a

Martian Atmospheric Loss Through Foreshock Transient Events
Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract At Mars, the MAVEN spacecraft has made observations of Hot Flow Anomalies (HFAs) in the foreshock. Due to the bow shock's proximity to the planet, it is theorized that HFAs contribute to atmospheric escape at Mars through the excavation of ionospheric ions.

The Dust Environment of Short Period Comets
, 2013 In this work we present a characterization of the dust environment of various Short Period Comets, with the purpose to improve the knowledge on their physical properties. Among this comet family members, we focused over 30P/Reinmuth 1, 78P/Gehrels 2, 123P/West-Hartley and P/2011 W2 (Rinner).

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract In Saturn's magnetosphere, the inward transport of magnetic flux is largely carried by localized injection flux tubes filled with warm, tenuous plasma, although their inflow speeds and spatio‐temporal properties remain poorly constrained. Here, we propose that these flux tubes can modify electron microsignatures, the small‐scale, absorption ...

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.
