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.

A Glimpse of a Brown Dwarf Binary Star System In Motion

Brown Dwarf GIF

When looking up at the night sky, it’s hard to imagine the stationary stars up above are actually continuously moving parts of the universe. 

Seven years worth of observational images taken by the Carnegie Astrometric Planet Search Camera (CAPSCam) were compiled to make an animated GIF revealing how a well-known brown dwarf binary system just 12 light-years from Earth, Epsilon Indi B, moves across the sky.

Two New Strainmeters Installed on Mt. Etna

Alan Linde

In November 2014, a DTM team led by Alan Linde travelled to Mt. Etna in Sicily, Italy, to install two strainmeters and double the number of such sites on the volcano. This program is in collaboration with the Istituto Nazionale di Geofisica e Vulcanologia  (INGV) of Italy with principal collaborator Alessandro Bonaccorso.

Mt. Etna, which is in an almost constant state of activity, is the tallest active volcano in Europe, currently reaching an elevation of 10,922 ft. On 28 December 2014, the volcano endured its most intense eruption since December 2013, which was well recorded by Linde and DTM staff member emeritus, Selwyn Sacks, thanks to their two newest strainmeters.
