Peaking Into Oberon's Past: An Isolated Peak Could Imply the Existence of a Subsurface Ocean or Convecting Ice Shell

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.
Abstract The Uranian moons, last visited in 1986 by Voyager 2, remain an intriguing yet under‐explored set of targets. Understanding the thermal structure and evolution of these moons is key to addressing one of the highest priority goals in planetary science: identifying if any are ocean worlds today or have been in the past. On Oberon, one feature in

Crater morphology and morphometry on the Uranian satellites [PDF]

, 1987
Fresh craters on the icy Uranian satellites exhibit a range of morphologies similar to craters on the icy satellites of Jupiter and Saturn. The general structural features found in the craters are described.

Highly Asymmetric Magnetosphere‐Ionosphere‐Thermosphere Coupling at Uranus

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Magnetosphere‐Ionosphere‐Thermosphere (MIT) coupling is widely considered the dominant energy source responsible for maintaining the elevated thermospheric temperatures observed at the giant planets. At Uranus, the strongly tilted and asymmetric magnetic field produces a highly asymmetric magnetospheric configuration that may fundamentally ...

Inclination of Miranda as a Constraint on the Tidal Dissipation of Uranus

The Planetary Science Journal
The five major moons of Uranus record a complicated geological history characterized by both tectonic resurfacing and heavy impact cratering, connecting their evolution to dynamical processes in the solar system.

On the Detection of Low‐Frequency Planetary Radio Emission With an Orbiting Interferometer

Radio Science, Volume 61, Issue 6, June 2026.
Abstract The magnetized planets of the outer Solar System produce kilometric radio emissions at very low frequencies (<1 ${< } 1\,$MHz). They reveal the planetary magnetic dynamics and their interaction with the solar wind. Those radio emissions can also serve as a proxy for interplanetary space weather monitoring.

Optical Spectroscopy of the Uranian Moons from Equinox to Northern Summer

The Planetary Science Journal
We present an analysis of ground-based visible and near-infrared wavelength (VIS, ∼0.4–0.9 μ m) reflectance spectra of the four largest Uranian satellites, utilizing observations with multiple telescopes, collected near Uranian equinox and in northern ...

Rotation‐Controlled Diurnal Evolution of Uranus' Asymmetric Bow Shock at Equinox

AGU Advances, Volume 7, Issue 3, June 2026.
Abstract Uranus possesses the most extreme magnetic and rotational geometry in the solar system, resulting in a uniquely dynamic and asymmetric interaction between its magnetosphere and the solar wind. Here we investigate the diurnal evolution of the Uranian bow shock (BS) at equinox using global multifluid magnetohydrodynamic simulations constrained ...

What Observations Would an Energetic Neutral Atom Imager Have Made During the Voyager 2 Flyby of Uranus?

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract We present large‐scale simulations of energetic neutral atom (ENA) emissions at Uranus from a spacecraft viewpoint. Models of magnetic field, extended hydrogen exosphere, moon‐sourced neutral tori, and proton radiation belt are implemented into a simulator to evaluate the production of ENAs for L $L$ = 1–15.

The 3:1 mean motion resonance between Miranda and the inner Uranian satellites, Cressida and Desdemona

, 2014
We build a simple dissipative analytical model considering an averaged restricted 3-body problem taking into account the effect of the oblateness of a planet on a small satellite and on its perturber.

Polarization Measurements and Source Locations of Saturn Electrostatic Discharges During the Voyager Era

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract A Saturn Electrostatic Discharge or SED is an intense electromagnetic impulse induced by Saturn lightning, which escapes into space through the magnetoplasma of the ionosphere. Since previous SED polarizations from Voyager data are inconclusive, this polarization study is the first which properly considers the characteristics of the Voyager ...
