Planetary science

Definition

Planetary science is the study of the celestial bodies that orbit stars, with a particular focus on our own solar system. This includes studying the formation and evolution of planets, the moons and rings that orbit them, and other smaller bodies such as asteroids and comets.

    Glacial meltwater from the Greenland Ice Sheet causes buoyancy-driven upwelling of nutrient-rich, subtropical waters from depth to the continental shelf. This nutrient transport may exceed the direct ice sheet inputs, according to geochemical analyses of transect samples from Sermilik Fjord.

    Infrared and neutron spectroscopic observations by Dawn give contrasting results on the elemental composition of Ceres’s surface, which can be reconciled by assuming that Ceres’s surface contains ~20 wt% of carbon, coming from impacts by carbonaceous asteroids and/or generated by extensive aqueous alteration.

    Changes in glacier speed in High Mountain Asia are closely linked to mass balance through gravitational driving stress, and largely insensitive to basal conditions, according to satellite-derived ice-flow observations.

    Permafrost thaw poses a serious threat to the sustainable development of Arctic communities. Here the authors show that most fundamental Arctic infrastructure and population will be at high hazard risk, even if the Paris Agreement target is achieved.

    Short-lived natural bromocarbons, which contribute to ozone depletion in the atmosphere, are believed to be produced through light-driven processes, mainly in oceans. Here the authors present bromocarbon measurements in snow, sea ice, and air during polar winter that show an unexpected source of bromine to the polar atmosphere during periods of no sunlight.
