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.

The GMT Groundbreaking Ceremony in Chile with Serge Dieterich


Serge Dieterich, NSF postdoctoral fellow at DTM, helped with the groundbreaking ceremonies for the Giant Magellan Telescope at Carnegie's Las Campanas Observatory in Chile on 11 November 2015. Below is Dieterich's first-hand account of the ceremony. 

"When finished, GMT will be a 25 meter diameter optical telescope that will allow Carnegie scientists, as well as scientists from other GMT Consortium members, unprecedented insights into the early universe, star and planet formation, action, and the search for life in other planets."
