The atmosphere of the Archean eon—one-third of Earth's history—is important for
understanding the evolution of our planet and Earth-like exoplanets. New geological proxies …

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 …

Earth's climate may be stabilized over millennia by solubilization of atmospheric carbon
dioxide (CO2) as minerals weather, but the temperature sensitivity of this thermostat is …

Methane is a potent greenhouse gas, which likely enabled the evolution of life by kee**
the early Earth warm. Here, we demonstrate routes towards abiotic methane and ethane …

The Hadean eon, following the global-scale melting of the mantle,–, is expected to be a
dynamic period, during which Earth experienced vastly different conditions. Geologic …

One popular view of Venus' climate history describes a world that has spent much of its life
with surface liquid water, plate tectonics, and a stable temperate climate. Part of the basis for …

The chemical reactions that formed the building blocks of life at origins required catalysts,
whereby the nature of those catalysts influenced the type of products that accumulated …

The flux balances of carbon and chlorine between subduction into the deep mantle and
volcanic emissions into the atmosphere are crucial for the habitability of our planet …

Water plays a critical role in erosion and sediment transport and this relationship is most
evident in the hyperarid Atacama Desert of Northern Chile, a region characterized by …

Prebiotic systems chemistry suggests that high phosphate concentrations were necessary to
synthesise molecular building blocks and sustain primitive cellular systems. However …
