The Deep Composition of Uranus and Neptune from In Situ Exploration and Thermochemical Modeling [PDF]
Space Science Reviews, 2020 The distant ice giants of the Solar System, Uranus and Neptune, have only been visited by one space mission, Voyager 2. The current knowledge on their composition remains very limited despite some recent advances.

Detecting an Ocean Inside Callisto With Geodetic Measurements From Europa Clipper and Juice
Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.Abstract Determining whether Callisto hosts a subsurface ocean, and the implications for material and energy transport through its hydrosphere, is of high interest to NASA's Europa Clipper and ESA's Juice missions. A recent reanalysis of Galileo magnetometer data strengthens the ocean hypothesis, but definitive confirmation awaits new measurements.

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

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 ...

Uranus's complex internal structure
Astronomy & AstrophysicsUranus's bulk composition remains unknown. Although there are clear indications that Uranus's interior is not fully convective, and therefore has a non-adiabatic temperature profile, many interior models continue to assume an adiabatic interior.
