Interior and Gravity Field Models for Uranus Suggest Mixed-composition Interior: Implications for the Uranus Orbiter and Probe

This is a montage of NASA Hubble Space Telescope views of our solar system's four giant outer planets: Jupiter, Saturn, Uranus, and Neptune, each shown in enhanced color. The images were taken over nearly 10 years, from 2014 to 2024. This long baseline allows astronomers to track seasonal changes in each planet's turbulent atmosphere, with the sharpness of the NASA planetary flyby probes of the 1980s. These images were taken under a program called OPAL (Outer Planet Atmospheres Legacy). NASA, ESA, Amy Simon (NASA-GSFC), Michael H. Wong (UC Berkeley); Image Processing: Joseph DePasquale (STScI)

Magnetic field of Uranus. (left) Magnetic field line geometry of Uranus for Winter Solstice and Spring Equinox in the Uranus–Sun–Orbit frame. The orbits of Miranda, Ariel, Umbriel, Titania and Oberon are shown. Independent of season, the magnetic field of Umbriel (as well as Miranda and Ariel) is well shielded from external effects of the magnetosphere, making it a robust target for magnetic induction investigation of its interior (right) Fourier transform of the magnetic field of Uranus evaluated at the position of Umbriel. Note that although there are many beats and harmonics of the two fundamental frequencies, only the synodic is used here for characterization owing to its dominance over the other frequencies. -- Philos Trans A Math Phys Eng Sci via PubMed

This zoomed-in image of Uranus, captured by Webb’s Near-Infrared Camera (NIRCam) Feb. 6, 2023, reveals stunning views of the planet’s rings. The planet displays a blue hue in this representative-color image, made by combining data from two filters (F140M, F300M) at 1.4 and 3.0 microns, which are shown here as blue and orange, respectively Credits: NASA, ESA, CSA, STScI.

Uranus’ Swaying Moons Will Help Spacecraft Seek Out Hidden Oceans

Models for the interior structures of the ice-giant planets Uranus and Neptune have two distinct, intermediate layers: an upper, water-rich convecting layer where disorganized magnetic fields are generated, and a lower, non-convecting hydrocarbon-rich layer. New computer simulations show that icy materials naturally separate at high pressure and temperature into these two layers. Credit Burkhard Militzer, UC Berkeley

A Clue To What Lies Beneath The Bland Surfaces Of Uranus And Neptune

Map of Miranda's southern hemisphere made using JMARS and a base map by P. M. Schenk (2013). The map is shown to give context to the regional maps of Arden Corona and Elsinore Corona in Figures 4 and 5. The map shows how Arden Corona and Elsinore Corona are on opposite hemispheres from each other and made up of concentric ridges. The upper mapped region represents Elsinore Corona. Elsinore Corona is divided between ropelike folded terrain in the south (ECFT), rugged ridged terrain in the northwest (ECRT) and a mixture of the two terrains to the northeast (ECMT). Ridges are positive relief grooves. Furrows are negative relief grooves. The lower region represents Arden Corona (AC). Arden Corona is made up of a series of furrows. Prominent impact basins are also mapped for geographic context. Elsinore Corona and Arden Corona are mapped in this figure because their analysis required higher-resolution imagery, but the cratered terrain and Inverness Corona are mapped only in Figure 3 because of lower-resolution requirements, since they were not the main focus of the study. Labels of each unit mapped are added to clarify colors because of transparency issues. -- The Planetary Science Journal

Is An Ocean Lurking Beneath Miranda?

The first panel of this artist’s concept depicts how Uranus’s magnetosphere — its protective bubble — was behaving before the flyby of NASA’s Voyager 2. The second panel shows an unusual kind of solar weather was happening during the 1986 flyby, giving scientists a skewed view of the magnetosphere. Credit: NASA/JPL-Caltech
