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 […]

Marine Science Can Contribute to the Search for Extra-Terrestrial Life
Abstract: Life on our planet likely evolved in the ocean, and thus exo-oceans are key habitats to search for extraterrestrial life. We conducted a data-driven bibliographic survey on the astrobiology […]

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.

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 […]

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, […]

Surface Volatile Composition as Evidence for Hydrothermal Processes Lasting Longer in Triton’s Interior Than Pluto’s
Ocean worlds, or icy bodies in the outer solar system that have or once had subsurface liquid water oceans, are among the most compelling topics of astrobiology. Typically, confirming the […]

Spectroscopic Detection of Biosignatures in Natural Ice Samples as a Proxy for Icy Moons
Some of the icy moons of the solar system with a subsurface ocean, such as Europa and Enceladus, are the targets of future space missions that search for potential extraterrestrial […]

Volatile Transport Modeling On Triton With New Observational Constraints
Neptune’s moon Triton shares many similarities with Pluto, including volatile cycles of N2, CH4 and CO, and represents a benchmark case for the study of surface-atmosphere interactions on volatile-rich KBOs. […]
