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.

Found: Oldest known planet-forming disk

Jonathan Gagne

A group of citizen scientists and professional astronomers, including DTM’s Jonathan Gagné, joined forces to discover an unusual hunting ground for exoplanets. They found a star surrounded by the oldest known circumstellar disk—a primordial ring of gas and dust that orbits around a young star and from which planets can form as the material collides and aggregates.

Celebrating the 2016 Postdoc Appreciation Week at Carnegie's Broad Branch Road Campus

Postdoc Week

For this year’s National Postdoc Appreciation Week, we had the honor of hosting Carnegie President Matt Scott, who presented a lecture on Wednesday, September 21, 2016, that went out to all Carnegie departments on “How to Give a Good Talk: Finding and Keeping a Job.” As light relief to the prospect of looking for a new job, DTM and the Geophysical Laboratory hosted a Postdoc Science Pictionary Party and taco dinner on Friday, September 23, on campus for all of our postdoctoral fellows and associates.
