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.About our research

After an NPR interview ran on May 16 quoting a male astronomer saying, "Many scientists, I think, secretly are what I call 'boys with toys'", the reactionary hashtag #girlswithtoys went viral on Twitter.
Female scientists from around the world posted photos of themselves on Twitter with the tools and machines they use to conduct their research everyday. Besides proving a point, the photos also provide a gateway into the fascinating equipment scientists use on a daily basis. Here are Carnegie's #girlswithtoys doing cool, smart science.
Over 120 people descended upon Carnegie's Broad Branch campus on Thursday, 14 May 2015, to hear DTM Astronomer Paul Butler reveal the truth about alien worlds and the origin of science for the final installment of Carnegie's 2014-15 Neighborhood Lectures Series.
In the past 20 years, more than a thousand extrasolar planets have been found, first from ground-based precision Doppler surveys, and more recently by the Kepler space mission. Butler and his colleagues have concentrated on building precise Doppler systems to survey the nearest stars. Systems at Lick, Keck, AAT, and Magellan have found hundreds of planets, including five of the first six extrasolar planets, the first saturn-mass planet, the first neptune-mass planet, the first terrestrial mass planet, and the first multiple planet systems.
DTM scientists regularly explore our planet and the universe. Along the way they capture images of stunning landscapes, geophysical processes and data visualizations.
