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.

Lara Wagner Journeys to the Center of the Earth at her Neighborhood Lecture


Friends and neighbors of Carnegie's Broad Branch Road Campus gathered in the Greenewalt Lecture Hall on Thursday, October 20, 2016, to listen to a sold out talk titled "Pointing the Telescope Down: Seismo-vision into the Earth" by DTM Staff Scientist Lara Wagner as part of our quarterly Neighborhood Lecture Series.

Found: Oldest known planet-forming disk

Jonathan Gagne

A group of citizen scientists and professional astronomers, including DTM’s Jonathan Gagné, joined forces to discover an unusual hunting ground for exoplanets. They found a star surrounded by the oldest known circumstellar disk—a primordial ring of gas and dust that orbits around a young star and from which planets can form as the material collides and aggregates.
