The generation of hydrogen and reduced carbon compounds during serpentinization provides sustained energy for microorganisms on Earth, and possibly on other extraterrestrial bodies (e.g., Mars, icy satellites).

The Pale Orange Dot: The Spectrum and Habitability of Hazy Archean Earth [PDF]
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 ...

Searching for Life, Mindful of Lyfe’s Possibilities
We are embarking on a new age of astrobiology, one in which numerous interplanetary missions and telescopes will be designed, built, and launched with the explicit goal of finding evidence for life beyond Earth.

Habitability of Exoplanet Waterworlds [PDF]
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 ...

Habitability of the marine serpentinite subsurface: a case study of the Lost City hydrothermal field
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 ...

Mineral dust increases the habitability of terrestrial planets but confounds biomarker detection [PDF]
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.

Habits of practice, habits of thought [PDF]
The years since the launch of this journal in 2000 have been as bountiful for scholars of journalism as they have been painful for practitioners scrambling to keep up with the dizzying pace of change. Our observations and explorations over time suggest that journalistic activities – what we might call ‘habits of practice’ – seem to be changing far more
