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.

    Collisions of dust particles with a planet’s atmosphere lead to the accumulation of metallic atoms at high altitudes. MAVEN spacecraft observations reveal a persistent—but temporally variable—metal layer of Mg+ ions in the Martian atmosphere.

    Brown carbon absorbs light, but its climate impacts in the upper troposphere are not well known. A series of aircraft observations in the US reveals that convection lofts brown carbon to high altitudes, causing greater warming than at lower altitudes.

    Isoprene emissions are commonly estimated using satellite measurements and model simulations. Here, using eddy covariance, the authors report higher emission rates over the Amazon forest than those estimated with these techniques and a relationship between terrain elevation and isoprene emissions.
