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.
