Probing methane in Uranus’ upper stratosphere using HST observations of the 1280 Å Raman feature
Astronomy & AstrophysicsWe analysed far-ultraviolet (FUV) spectra of Uranus obtained by the HST STIS and COS instruments in 2012 and 2014, respectively, to determine the brightness of Raman-scattered Lyman-alpha (Lyα) emissions centred at 1280 Å (hereafter, the Raman feature ...

Soft X‐Ray Emission From Saturn's Magnetosheath Part I: 3D Modeling From MHD Data
Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.Abstract Saturn's magnetosheath hosts a mixed population of water‐group neutrals and solar wind plasma. We present a 3‐D model of soft X‐ray emission by ion‐neutral charge exchange in the near‐equatorial magnetosheath. The model employs MHD simulation data of plasma properties at Saturn, Enceladus‐genic neutral populations extrapolated from existing ...

Noble Gas Planetology and the Xenon Clouds of Uranus
The Planetary Science JournalNoble gases provide tracers of cosmic provenance that are accessible to a future Uranus atmospheric probe. Argon and krypton are expected to be well mixed on Uranus with respect to H _2 and He, although condensation at the winter pole may be possible ...

Kelvin‐Helmholtz Stability Analysis as a Function of Dipole Tilt and Solar Wind Property
Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.Abstract Kelvin‐Helmholtz instabilities (KHIs) play a critical role in facilitating mass and momentum transport across the magnetopause boundary. Recent studies have demonstrated that KHI occurrence exhibits both seasonal and diurnal variability, with enhanced activity when Earth's magnetic dipole is more closely aligned with the northward direction in

Observations of Uranus at High Phase Angle as Seen by New Horizons
The Planetary Science JournalWe present flux measurements of Uranus observed at phase angles of 43.°9, 44.°0, and 52.°4 by the Multispectral Visible Imaging Camera on the New Horizons spacecraft during 2023, 2010, and 2019, respectively.

Uranus’s Influence on Neptune’s Exterior Mean-motion Resonances
The Planetary Science JournalNeptune’s external mean-motion resonances play an important role in sculpting the observed population of trans-Neptunian objects (TNOs). The population of scattering TNOs is known to “stick” to Neptune's resonances while evolving in semimajor axis ( a ),

Wide‐Range Adaptive Metal Oxide for Hydrogen Sulfide Detection From Earth to Space‐Like Environments
Advanced Science, Volume 13, Issue 19, 2 April 2026.This work presents a gas sensing platform based on Cu‐doped SnO2 microspheres that operates reliably from ambient to space‐like conditions. The sensor maintains performance across vacuum and cryogenic environments, bypassing traditional oxygen‐mediated mechanisms, utilizing direct chemisorption and interfacial charge transfer.
