The Astrobiological Potential of the Uranian Moon System
The 2023-2032 Planetary Science and Astrobiology Decadal Survey prioritized the Uranus Orbiter and Probe (UOP) mission concept as the next priority flagship mission. The UOP concept includes scientific studies of […]

Webb Observes Carbon Oxides On Uranus’ Moon Ariel That Hint At A Hidden Ocean
The surface of Uranus’ moon Ariel is coated with a significant amount of carbon dioxide ice, especially on its “trailing hemisphere” that always faces away from the moon’s direction of […]

JWST Spectrophotometry of the Small Satellites of Uranus and Neptune
We use 1.4-4.6 micron multi-band photometry of the small inner Uranian and Neptunian satellites obtained with the James Webb Space Telescope’s near-infrared imager NIRCam to characterize their surface compositions.

The Effect Of Lightning On The Atmospheric Chemistry Of Exoplanets And Potential Biosignatures
Lightning has been suggested to play a role in triggering the occurrence of bio-ready chemical species. Future missions (PLATO, ARIEL, HWO, LIFE) and ground-based ELTs will investigate the atmospheres of […]

Feasibility of Passive Sounding of Uranian Moons using Uranian Kilometric Radiation
We present a feasibility study for passive sounding of Uranian icy moons using Uranian Kilometric Radio (UKR) emissions in the 100 – 900 kHz band.

A New Study of Uranus’ Large Moons Shows That Four May Hold Water
Re-analysis of data from NASA’s Voyager spacecraft, along with new computer modeling, has led NASA scientists to conclude that four of Uranus’ largest moons likely contain an ocean layer between […]

Two Of Uranus’ Moons May Harbor Active Oceans, Radiation Data Suggests News Releases
Uranus — the turquoise, tilted oddball of the solar system — may have just joined ranks with Jupiter, Saturn and Neptune as host to at least one icy moon that’s […]

In Search Of Subsurface Oceans Within The Uranian Moons
The Galileo mission to Jupiter discovered magnetic signatures associated with hidden sub-surface oceans at the moons Europa and Callisto using the phenomenon of magnetic induction. These induced magnetic fields originate […]

The Science Case For Spacecraft Exploration Of The Uranian Satellites: Candidate Ocean Worlds In An Ice Giant System
The 27 satellites of Uranus are enigmatic, with dark surfaces coated by material that could be rich in organics. Voyager 2 imaged the southern hemispheres of Uranus’ five largest ‘classical’ […]
