We explore & discover

Scientists at the Department of Terrestrial Magnetism (DTM) bring the perspective of several disciplines to broad questions about nature. DTM's name comes from its original role to chart the Earth's magnetic field. This goal was largely accomplished by 1929. Since then, DTM has evolved to reflect the growing multi-disciplinary nature of the Earth, planetary, and astronomical sciences. Today, the historic goal remains to understand the physical Earth and the universe that is our home.

Science at the Bar!

Astronomy on Tap Tour in DC

This week, DTM postdoctoral fellow Jackie Faherty kick started the popular bar “talk” series, Astronomy on Tap (AoT), in Washington D.C. at the Science Club. AoT originally began in New York City, as a brainchild of Meg Schwamb when she was a postdoctoral fellow at Yale University from 2010 to 2013. 

The esteemed panel at the innagural D.C. AoT talk included Faherty herself, a Brown Dwarf Wrangler, NASA Goddard Space Center’s Planethunter Michael McElwain, and two of Faherty's DTM colleagues, Volcanologist Diana Roman and Dwarf Planet Expert Scott Sheppard. Over 45 people poured into the room and overtook every inch of the space, proving this series will thrive at future AoT satellite events in Washington D.C.

Opening Day at Broad Branch Road, 1914

Opening day at BBR

The Carnegie Institution celebrates a century of science and discovery at its Washington, DC, campus this month. Learn about our campus history and join us at one of our events in commemeration of our centennial.

April 1, 1914 was cool and rainy, but spirits must have been high among the scientists and staff of the Department of Terrestrial Magnetism. After ten years quartered in rented rooms in the Ontario Apartment House near the National Zoo, the Department marked the start of its eleventh year on its own new campus “out in the country” on Washington’s northwest fringe.
