Exploring The Orbital Stability Of Large, Lightweight Mirrors Around Exoplanets
Extraterrestrial civilizations might place large, lightweight mirrors into orbit around an exoplanet, either to alter its climate or to provide illumination to the planet’s dark side. We previously analyzed the […]

ExoMars Rosalind Franklin Astrobiology Rover Targets A Vast Bed Of Clay In Its Search For Life
In the region where the ExoMars Rosalind Franklin rover will search for signs of life, clay deposits extend beyond previous estimates, a new study finds. One hypothesis even suggests a […]

Maximum Lifetime Of The Vegetative Biosphere
We use a three-dimensional model to calculate steady-state climates at various intervals in Earth’s future, across a parameter space of increasing insolation and decreasing CO2 mixing ratio.

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 […]
