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.

    Observations reveal that electrons in Earth’s outer radiation belt possess a spectrum that partially rises with increasing energy, contrary to common beliefs. Plasma hiss waves scattered off electrons are found to be the origin of this phenomenon.

    Groundwater model results and hydrologic data sets reveal that half of global groundwater fluxes may equilibrate with climate-driven recharge variations on human timescales, indicating that hydraulic memory may buffer climatic change impacts.

    Using SN 1987A as a cosmic laboratory, Miceli et al. have measured the shock acceleration of ions heavier than oxygen, finding that the post-shock temperature of a wide range of ions is mass dependent.

    Ocean warming contributes to the thinning of the Antarctic ice shelves, however, lack of observations has prevented a quantification of this contribution. Here the authors use geological records to show that 0.3–1.5 °C ocean warming has played a central role on regional ice shelf instability over the last 9000 years.
