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.

Postdoc Spotlight: Astronomer Johanna Teske

Johanna Teske

The search for life outside our planet has always inspired joint DTM and Carnegie Observatories Origins fellow Johanna Teske to pursue astronomy, and now she can't imagine doing anything else. We asked Teske about how she first became interested in astronomy, and what she will be researching during the second part of her Origins fellowship at the Carnegie Observatories in Pasadena, CA, starting in August 2016. 

New Paper Published by Scott Sheppard and Colleagues Details The Discovery of a Collection of New Objects Beyond the Kuiper Belt Edge

Scott Sheppard

The hunt for Planet X, the hypothetical ninth major planet in our solar system, has led Scott Sheppard and collaborators to the discovery of a collection of new objects located in the outer reaches of our solar system beyond the Kuiper Belt edge at 50 au. This work is now published in The Astrophysical Journal Letters.
