About Us

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.

Carnegie Alum discusses JWST on C-Span as EPL scientists prepare their projects


Former Carnegie postdoctoral fellow Meredith MacGregor, now an Assistant Professor at the University of Colorado, joined Susan Swain on C-Span for a Q&A session on NASA’s James Webb Space Telescope. During the interview, MacGregor discusses how this new telescope will use infrared light to peer into the early development of our Universe. She also explains that scientists, like those at the Earth and Planets Laboratory, will use the telescope to probe and characterize the atmospheres of faraway planets.
