Bernard Burke, who co-discovered Jupiter’s “voice,” dies at 90. With deep sadness, the Carnegie Institution's Department of Terrestrial Magnetism reports the passing of Bernard Burke, distinguished MIT astrophysicist and former DTM Staff Scientist.
Maggie Thompson, former DTM Research Trainee and now doctoral student at UC Santa Cruz, flew on the Stratospheric Observatory for Infrared Astronomy (SOFIA) on August 22. While a pre-doc at DTM in 2016-2017, Thompson worked with Alycia Weinberger on studying the dust around an extremely dusty, old star called BD+20 307. Using data taken with the infrared spectrograph (FORCAST) on SOFIA, they found that the disk got brighter over time. This object is the dustiest disk known and probably resulted from a massive collision of giant asteroids. Thompson and Weinberger  recently submitted a paper with these results to the American Astronomical Society Journals. They also applied to continue studying the dust with SOFIA. On August 22, Thompson flew on board SOFIA. She helped collect new observations to test whether the disk has continued to change in brightness or composition. The flight lasted 10 hours and zigzagged over the western US. The SOFIA aircraft, a joint mission by NASA and the German Aerospace Center, is a Boeing 747 with a door that opens to let a 2.5 m telescope observe while flying above most of the water vapor in Earth's atmosphere.
A group of teachers from across the United States visited Carnegie’s Broad Branch Road (BBR) campus on August 2 as part of the Smithsonian Science Education Academy for Teachers (SSEAT), a program designed to introduce K-12 teachers to world-class scientists and science education resources. The teachers toured BBR facilities and met DTM and Geophysical Laboratory scientists who gave lectures and presentations about geochemistry  and BBR's state of the art instrumentation.
Meredith Macgregor   gave an invited talk titled, "Exploring grain and gas properties in debris disks with millimeter interferometry," at the Cosmic Dust XI meeting held on August 13-17 in Sagamihara, Japan.

DTM scientists presented their research at the annual Goldschmidt conference held on August 12-17 in Boston.
As chair of the NASA Exoplanet Exploration Program's Technology Assessment Committee, Alan Boss led a review on August 7 of the draft plan to develop the technology needed to fly a star shade that would allow future space telescopes to take images and spectra of Earth-like exoplanets orbiting nearby stars. Boss, also as chair of the NASA WFIRST Coronagraphic Instrument (CGI) Independent Review Team,  participated in a telecon on August 9 to review options for lowering the cost of the CGI while preserving its ability to advance the technology of coronagraphic imaging of exoplanets.
Giant Magellan Telescope excavation begins. GMTO announced the start of hard rock excavation for the Giant Magellan Telescope's massive concrete pier and the foundations for the telescope's enclosure on its site at Las Campanas Observatory in Chile.

Elodie Brothelande joined DTM’s volcanology team as a Postdoctoral Fellow following a fellowship at the University of Miami where she used GPS and InSAR to evidence temporal relationships between events affecting neighboring volcanoes in Japan and Galápagos.  Her PhD is in Volcanology from the Université B. Pascal, Clermont-Ferrand, France.
DTM welcomed new Instrument Maker, Steven Bassin. A certified machinist, welder, and industrial electrician with experience in sheet metal equipment, Bassin has worked for the Naval Research Center, Bassonics, Howard Hughes Medical Institute, and Orbital Sciences, where he was involved in research and development laboratory activities.
