Michigan Meteorite at Field Museum

Mon, 02/12/2018 - 12:49 -- pheck

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. Pritzker Associate Curator Philipp Heck and Resident graduate student Jennika Greer (Univ.

Mysterious Object from Beyond has significant shock value.

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).

McKay Award for PhD Student Jennika Greer

Resident Ph.D. Student Jennika Greer (Univ. of Chicago/Geophysical Sciences) has been selected to receive the McKay Award,* which honors the best student oral presentation at the Meteoritical Society Annual Meeting. This is particularly impressive, since this was her first oral presentation at a major scientific meeting. Jennika’s project focused on the analysis of a lunar sample to study the effects of space weathering, which affects airless bodies such as the Moon and asteroids.

The asteroidal source of the Park Forest meteorite

Park Forest

A bit more than 14 years ago, a 2-6 ton space rock entered the Earth's atmosphere. It broke up above Chicagoland, and up to 100 kg of fragments fell into southern suburb of Park Forest, which now lends its name to the meteorite. The new study published by Matthias Meier, a researcher at the Swiss Federal Institute of Technology and a former graduate student of Robert A.

The Field Museum of Natural History in Chicago opened a brand new exhibit on meteorites in February 2017. The exhibit features an exclusive display of four rare fossil meteorites that fell to Earth into an ocean 466 million years ago. In the Americas this is the only place which has fossil meteorites on exhibit. These rare specimens were loaned from private collector Mario Tassinari from Sweden.

Bright fireball over the Midwest

On Monday, February 6, 2017 around 1:30 AM local time many inhabitants of the Midwest saw a bright fireball shooting across the night sky. Some even heard a sonic boom. The Field Museum's Invertebrate Collections Manager Paul Mayer woke up from the sonic boom: "I was staying in Fredonia, Wisconsin and was woken up by a large boom that shook the whole house. It sounded like thunder and I thought maybe it was a train hitting something. I got up and looked out the window, but did not see anything.

Two papers on CAIs from Murchison published

University of Chicago postdoctoral scientist Levke Kööp, Robert A. Pritzker Associate Curator Philipp Heck, and colleagues from the Universities of Chicago, Wisconsin, and Hawaii, recently published two articles in the journal Geochimica and Cosmochimica Acta. The focus of their work was on some of the first materials that formed in the Solar System, i.e., inclusions in meteorites rich in the mineral hibonite.

Analysis of micrometeorites reveals H chondrite needles in L Chondrite haystack

Philipp Heck (Robert A. Pritzker Associate Curator of Meteoritics and Polar Studies), Surya Rout (Postdoctoral Research Scientist), Krysten Villalon (Univ. of Chicago Graduate Student) and Lund University’s Professor Birger Schmitz (also a Field Museum Research Associate) with colleagues from the University of Wisconsin published a new paper on 470-million-year-old fossil micrometeorites recovered from marine sediments in Sweden and Russia.
