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.Subscribe today About our research

New planetary formation models from DTM's Alan Boss indicate that there may be an undiscovered population of gas giant planets orbiting around Sun-like stars at distances similar to those of Jupiter and Saturn. His work is published by The Astrophysical Journal.
Jesse Reimink has been around science and the outdoors his entire life. His father, a high school biology teacher, would keep him and his sister busy searching for rocks and insects outside for their collections. Today, as a postdoctoral fellow at DTM, his rock collection has grown exponentially. This summer, he collected over 1200-pounds worth of samples from the Slave craton, a block of rocks in north-western Canada that has preserved a large amount of old rocks ranging in age from 4 billion to 2.5 billion years old.
DTM scientists regularly explore our planet and the universe. Along the way they capture images of stunning landscapes, geophysical processes and data visualizations.
