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

In the race to discover a proposed ninth planet in our Solar System, DTM’s Scott Sheppard and Chadwick Trujillo of Northern Arizona University have observed several never-before-seen objects at extreme distances from the Sun in our Solar System. Sheppard and Trujillo have now submitted their latest discoveries to the International Astronomical Union’s Minor Planet Center for official designations. A paper about the discoveries has also been accepted to The Astronomical Journal.
An international team of astronomers including DTM’s Paul Butler has found clear evidence of a planet orbiting Proxima Centauri, the closest star to our Solar System. The new world, designated Proxima b, orbits its cool red parent star every 11 days and has a temperature suitable for liquid water to exist on its surface, if it were present. This rocky world is a little more massive than the Earth and is the closest exoplanet to us; it may even be the closest possible abode for life beyond our own Sun. A paper describing this milestone finding is published by Nature.
DTM scientists regularly explore our planet and the universe. Along the way they capture images of stunning landscapes, geophysical processes and data visualizations.
