Despite its relatively minor abundance in magmas (compared with H2O and CO2), sulfur
degassing from volcanoes is of tremendous significance. It can exert substantial influence …

The advent of radial velocity (RV) and transit photometry method has resulted in the
detection of more than 5000 exoplanets since 1995. Of these detected planets, a significant …

Geological evidence shows that ancient Mars had large volumes of liquid water. Models of
past hydrogen escape to space, calibrated with observations of the current escape rate …

The presence of valleys on ancient terrains of Mars suggests that liquid water flowed on the
martian surface 3.8 Gyr ago or before. The above-freezing temperatures required to explain …

The Precambrian history of our planet is marked by two major events: a pulse of continental
crust formation at the end of the Archaean eon and a weak oxygenation of the atmosphere …

We present here new experimental data on H2O–CO2 solubility in mafic melts with variable
chemical compositions (alkali basalt, lamproite and kamafugite) that extend the existing …

Magmatic degassing is ubiquitous and enduring, yet its impact on both planetary surficial
chemistry and how it may have varied among planetary systems remains imprecise. A large …

Volcanic emissions link the oxidation state of the Earth's mantle to the composition of the
atmosphere. Whether the oxidation state of an ascending magma follows a redox buffer …

The widespread evidence for liquid water on the surface of early Mars is difficult to reconcile
with a dimmer early Sun. Many geomorphological features suggestive of aqueous activity …

Chemical data from the MESSENGER spacecraft revealed that surface rocks on Mercury are
unusually enriched in sulfur compared to samples from other terrestrial planets. In order to …
