In the coming years and decades, advanced space-and ground-based observatories will
allow an unprecedented opportunity to probe the atmospheres and surfaces of potentially …

Rocky planets are common around other stars, but their atmospheric properties remain
largely unconstrained. Thanks to a wealth of recent planet discoveries and upcoming …

Habitability is a widely used word in the geoscience, planetary science, and astrobiology
literature, but what does it mean? In this review on habitability, we define it as the ability of …

Recognizing whether a planet can support life is a primary goal of future exoplanet spectral
characterization missions, but past research on habitability assessment has largely ignored …

The TRAPPIST-1 planetary system provides an unprecedented opportunity to study
terrestrial exoplanet evolution with the James Webb Space Telescope (JWST) and ground …

Finding life on exoplanets from telescopic observations is an ultimate goal of exoplanet
science. Life produces gases and other substances, such as pigments, which can have …

The detection of exoplanets orbiting other stars has revolutionized our view of the cosmos.
First results suggest that it is teeming with a fascinating diversity of rocky planets, including …

The TRAPPIST-1 system, consisting of an ultracool host star having seven known Earth-
sized planets, will be a prime target for atmospheric characterization with the James Webb …

The prospects for the habitability of M-dwarf planets have long been debated, due to key
differences between the unique stellar and planetary environments around these low-mass …

The implications of the water vapor runaway greenhouse phenomenon for water-rich sub-
Neptunes are developed. In particular, the nature of the postrunaway equilibration process …
