Planetary Science & Astronomy

Exploring the workings of our solar system provides a window into Earth’s past, with implications for our future. The study of magnetic fields of meteorites has helped establish a timeline for how quickly our solar system emerged from its protoplanetary nebula, and offers insights into the early composition of planetary bodies as they formed. The atmospheric extremes of other planets can tell us about our own climate and its potential changes, whether it be the cooling effects of dust, the heat-trapping properties of carbon dioxide, or even interactions with the solar wind. And as we continue to discover the existence of water and organic molecules elsewhere in the solar system, we are given more clues to the origins of life on Earth—and the tantalizing prospect of detecting life beyond our own planet.
