The Catastrophic Consequences of Agnosticism for Life Searches and a Possible Workaroun
Planned and ongoing searches for life, both biological and technological, confront an epistemic barrier concerning false positives – namely, that we don’t know what we don’t know.

Synergistic Effects of Ocean Salinity and Planetary Obliquity Enhance Habitability of Cold Exo-Earths
Past work has shown that ocean salinity and planetary obliquity both influence the climates of Earth-like exoplanets throughout the habitable zone of Sun-like stars. The effects of salinity and obliquity […]

Smaller Than Earth Habitability Model (STEHM): The Lower Size Limit for Atmosphere Retention in the Habitable Zone
With recent advances in exoplanet observational techniques enabling the discovery of increasingly smaller planets, a crucial question emerges in the search for habitable planets: how small can a planet be […]

Flare-driven Habitability: Expanding Life’s Potential Around Low-mass Stars
The traditional definition of the circumstellar habitable zone (HZ) focuses on liquid water, but neglects the crucial role of ultraviolet (UV) radiation in prebiotic chemistry.

Astrochemical Inheritance of Terrestrial Planets Water from Local Wet Silicates
The delivery of water to the inner Solar System rocky planets, including Earth, remains debated, as standard models assume that they formed from dry grains, inside the snowline of the […]
