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.

Earth and Planets Laboratory Contributes to DC’s Essential Workers in Fight Against Coronavirus

3D Printed Parts

Carnegie Science’s Earth and Planets Laboratory (EPL) is putting its 3D printers to work in the worldwide fight against the coronavirus pandemic. Staff Scientist Tim Strobel is heading up an effort with Postdoctoral Fellow Wan Si Tang and Laboratory Engineer Javier Rojas to print an essential part for transparent face shields. When used in conjunction with low-grade surgical masks, these shields provide CDC-recommended levels of protection for healthcare workers interacting with a COVID-19 carrier. In addition to the 3D printing project, several EPL staff members are contributing their time and skills to supply local medical institutions. 

Earth and Planets Lab Provides Digital Outlet for Cancelled Conference Presentations


On April 1, 2020, Deputy Director Mike Walter organized a virtual meeting that brought together scientists from Carnegie Science, the University of Maryland, and the Smithsonian to present the work they would have shared at the canceled Lunar and Planetary Science Conference (LPSC). During the day-long digital meeting, named LPSC-Z after the original meeting, nine planetary scientists presented their talks to nearly 50 attendees on topics ranging from planetary disk formation to mantle melt chemistry.
