A Localized and Surprising Source of Energetic Ions in the Uranian Magnetosphere Between Miranda and Ariel

Geophysical Research Letters, 2023
In situ exploration of Uranus has been limited to a single flyby encounter by the Voyager 2 spacecraft in January 1986. Nonetheless, new investigation has led to significant questions about the origin of energetic ions observed in the region between its ...

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

Massive Rocky Planets May Suppress Deep Melting

AGU Advances, Volume 7, Issue 4, August 2026.
Abstract Melting properties of silicates are critical to understanding the thermal evolution of rocky planetary interiors. In the deep mantles of massive rocky planets, post‐post‐spinel Mg2SiO4 ${\text{Mg}}_{2}{\text{SiO}}_{4}$ is potentially one of the most abundant mineral phases, yet its melting behavior remains unconstrained. Here, we determine the

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 ...

Detection of stratospheric HCN and tropospheric CO in Uranus and the implication for their sources

Astronomy & Astrophysics
Context. Uranus belongs to the category of ice giants that are common in our Galaxy. However, Uranus is one of the least explored and understood planets in our Solar System. Aims.

Strong Tidal Dissipation at Uranus?

The Planetary Science Journal, 2023
Geophysical estimates of paleo heat fluxes on the Uranian moons Miranda and Ariel are in the range of 25–75 mW m ^−2 . For a canonical Uranus dissipation factor Q = 18,000, expected equilibrium tidal heating rates for these satellites are less than 6 mW ...
