Planetary Science

Where do we come from? How did our solar system come to be the way it is? Are we alone? By studying the makeup and evolution of Earth, our solar system, and planets orbiting distant stars, Caltech’s astronomers, geologists, planetary scientists, and environmental scientists and engineers are collaborating to tackle these questions. Your support can help Caltech leverage its historic partnership with JPL and unparalleled access to observatories to reveal some of the universe’s greatest mysteries.
