Habitability of the marine serpentinite subsurface: a case study of the Lost City hydrothermal field
Philosophical Transactions of the Royal Society A, 2020 The Lost City hydrothermal field is a dramatic example of the biological potential of serpentinization. Microbial life is prevalent throughout the Lost City chimneys, powered by the hydrogen gas and organic molecules produced by serpentinization and its ...

The Pale Orange Dot: The Spectrum and Habitability of Hazy Archean Earth [PDF]
Astrobiology, 2016 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 vastly different conditions that have existed in our planet's ...

Multiverse Predictions for Habitability: Origin of Life Scenarios
Universe, 2023 If the origin of life is rare and sensitive to the local conditions at the site of its emergence, then, using the principle of mediocrity within a multiverse framework, we may expect to find ourselves in a universe that is better than usual at creating ...

Life, 2021 There are two types of rogue planets, sub-brown dwarfs and “rocky” rogue planets. Sub-brown dwarfs are unlikely to be habitable or even host life, but rocky rogue planets may have a liquid ocean under a thick atmosphere or an ice layer.

Habitability of Exoplanet Waterworlds [PDF]
Astrophysical Journal, 2018 Many habitable zone (HZ) exoplanets are expected to form with water mass fractions higher than that of the Earth. For rocky exoplanets with 10–1000× Earth’s H2O but without H2, we model the multi-Gyr evolution of ocean temperature and chemistry, taking ...

Atmospheric escape from the TRAPPIST-1 planets and implications for habitability [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 2017 Significance The search for exoplanets has rapidly emerged as one of the most important endeavors in astronomy. This field received a major impetus with the recent discovery of seven temperate Earth-sized exoplanets orbiting the nearby ultracool dwarf ...

Mineral dust increases the habitability of terrestrial planets but confounds biomarker detection [PDF]
Nature Communications, 2020 Identification of habitable planets beyond our solar system is a key goal of current and future space missions. Yet habitability depends not only on the stellar irradiance, but equally on constituent parts of the planetary atmosphere.

Stellar flares versus luminosity: XUV-induced atmospheric escape and planetary habitability [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2020 Space weather plays an important role in the evolution of planetary atmospheres. Observations have shown that stellar flares emit energy in a wide energy range (1030–1038 erg), a fraction of which lies in X-rays and extreme ultraviolet (XUV).
