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 […]

Insights on the Formation Conditions of Uranus and Neptune from their Deep Elemental Compositions
This study, placed in the context of the preparation for the Uranus Orbiter Probe mission, aims to predict the bulk volatile compositions of Uranus and Neptune. Using a protoplanetary disk […]

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.

Constraints On Triton’s Atmospheric Evolution From Occultations: 1989-2022
Context – Around the year 2000, Triton’s south pole experienced an extreme summer solstice that occurs every about 650 years, when the subsolar latitude reached about 50°. Bracketing this epoch, […]

Neptune-like Exoplanets Can Be Cloudy Or Clear — New Findings Suggest The Reason Why
The study of “exoplanets,” the sci-fi-sounding name for all planets in the cosmos beyond our own solar system, is a pretty new field. Mainly, exoplanet researchers like those in the […]
