Astronomy and planetary science


Astronomy and planetary science are the study of objects and phenomena that occur beyond the Earth’s atmosphere. This includes investigating stars and their interaction with each other and the planetary systems that orbit them.

    Current estimates of dissolved CO2 in subduction-zone fluids based on thermodynamic models rely on a very sparse experimental data base. Here, the authors show that experimental graphite-saturated COH fluids interacting with silicates at 1–3 GPa and 800 °C display unpredictably high CO2 contents.

    A decrease in mafic continental crust coincides with the rise of O2 in the Earth’s surface environments about 3 billion years ago, according to an analysis of sediment chemistry. Reduced rates of serpentinization of mafic material, which produces chemicals that react with O2, could explain the link.

    Hydropower represents the largest source of renewable energy currently available, yet its potential provision remains poorly characterized. Gernaat et al. present a high-resolution global assessment of technical and economic hydropower potential based on an analysis of over 3.8 million individual locations.
