At the Earth and Planets Laboratory, we work at the frontier of human knowledge. We discover new worlds, create new materials, illuminate the inner workings of our planet, and seek to understand the universe that is our home. In 2020 we merged the Department of Terrestrial Magnetism (est.1904) and the Geophysical Lab (est.1905) to create a new multidisciplinary department. By combining a century of scientific trailblazing, we are better suited than ever to collaborate, discover, and innovate.
