With funding from the Polar Studies Program of the Robert A. Pritzker Center for Meteoritics and Polar Studies Genome Analyst Felix Grewe journeys to Antarctica to collect Usnea lichens. A unique hybrid of algae and fungus, lichens are early predictors of climate change. Step into this extreme and beautiful environment. Thanks to Thorsten Lumbsch, Leopold G.

Philipp Heck (Robert A. Pritzker Associate Curator for Meteoritics and Polar Studies) and collaborators from the University of Maryland and the University of California at Davis report on the rapid effects of terrestrial alteration of a pristine meteorite in a new article in Meteoritics & Planetary Science: The meteorite was seen falling in April 2012 over California’s Sierra foothills and landed near Sutter’s Mill (where the 1848–49 Gold Rush started).

Field Museum team completed naming and classification of meteorite that fell in Michigan in January.

The Field’s team consisting of University of Chicago graduate student Jennika Greer and Robert A. Pritzker Associate Curator Philipp Heck used scanning electron microscopy with X-ray spectroscopy and Raman spectroscopy to classify the rock as a very weakly shocked H4 chondrite. Out of about 60,000 confirmed meteorites, only about 0.1 percent are H4 chondrite falls. The meteorite is now officially named after Hamburg, Michigan.

A bright fireball streaked across the sky on January 16, 2018 near Detroit. The shockwave through the air caused a magnitude 2.0 earthquake in the area. Meteorite hunter Robert Ward used a strewn field map generated through Doppler radar data from NASA collaborator Marc Fries to search for meteorites. He found several pieces, and donated one to the Field. The connection to Robert Ward is thanks to long-time Field Museum supporter and private meteorite collector Terry Boudreaux. Robert A.

No, it’s not a sci-fi movie, but rather the unique Swedish fossil meteorite Oesterplana 065 which is the subject of a paper published last week in Meteoritics & Planetary Science by Postdoctoral Scholar Surya Rout (now at the University of Bern, Switzerland), Robert A. Pritzker Associate Curator for Meteoritics and Polar Studies Philipp Heck, and Field Museum Research Associate and Professor of Geology Birger Schmitz (Lund University of Sweden).
