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 […]
Atmospheric Science Questions for a Uranian Probe
The Ice Giants represent a unique and relatively poorly characterized class of planets that have been largely unexplored since the brief Voyager 2 flyby in the late 1980’s.
Increasing the Usability and Accessibility of Voyager 2 Images of Triton
Much of what we know about Neptune’s moon Triton was inferred from the analysis of images returned by the Voyager 2 mission, the only spacecraft to have visited that putative […]
The Voyager 1 Interstellar Probe Is Returning Science Data From All Four Instruments
NASA’s Voyager 1 spacecraft is conducting normal science operations for the first time following a technical issue that arose in November 2023.
Talking Interstellar: Six Deep Space Network Antennas in Madrid Arrayed For the First Time
“We must reach far beyond our own lifespans. We must think not as individuals but as a species. We must confront the reality of interstellar travel.” — Professor Brand “Interstellar”. […]
New Constraints On Triton’s Atmosphere From The 6 October 2022 Stellar Occultation
The atmosphere of Triton was probed directly by observing a ground-based stellar occultation on 6 October 2022. This rare event yielded 23 positive light curves collected from 13 separate observation […]
Calibrating Instruments For Exoplanets: What Neptune And Uranus Really Look Like
Neptune is fondly known for being a rich blue and Uranus green – but a new study has revealed that the two ice giants are actually far closer in colour […]
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 […]
