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.

June 2016 Letter from the Director

Letter from the Director June 2016

This month saw the first workshop of the new Science and Society initiative of Carnegie Science, headed by David and Edith Tatel. The topic of the first workshop was “Handling Hazards” and involved DTM’s Diana Roman, Lara Wagner, and Richard Carlson. During this workshop, it became obvious to Carlson that science has a clear, important, and effective role to play in hazard mitigation. Read about Carlson's revelations from the workshop in this month's Letter from the Director.

When It Comes To Brown Dwarfs, "How Far?" Is A Key Question

Artist

Brown dwarfs are sometimes called failed stars. They’re stars’ dim, low-mass siblings and they fade in brightness over time. They’re fascinating to astronomers for a variety of reasons, but much about them remains unknown. New work from a Carnegie-led team reports the distances of a number of brown dwarfs, as well as low-mass stars, in The Astronomical Journal.
