Presolar Grain Workshop

Mon, 01/21/2013 - 14:28 -- pheck

From January 25-27, 2013 the Annual Presolar Grains Workshop was held in Chicago. At this informal gathering cosmochemists and astrophysicists met and talked about how the study of presolar grains can help improve our understanding of how stars work. The successful meeting was held with talks at the University of Chicago, a dinner at the Field Museum and tours through the labs and collection of the Robert A. Pritzker Center for Meteoritics and Polar Studies.

Science paper: The Sutter's Mill Meteorite

Robert A. Pritzker Assistant Curator of Meteoritics and Polar Studies Dr. Philipp R. Heck is co-author on a paper in the journal Science on the first results of the rare meteorite, Sutter’s Mill. On April 22 a very fast-moving fireball was observed over large parts of California and Nevada. Equivalent to four kilotons of TNT, the fireball was photographed, and recorded by video and by weather Doppler-radars. The photographs and videos helped to trace back its orbit to the far reaches of the outer part of the asteroid belt.

When a meteor hits the earth, there is the possibility that it brings something very rare along with it: cosmic stardust older than our Solar System. Dr. Philipp Heck and his team of scientists use a combination of geosciences, chemistry, and astronomy to hunt for these presolar grains, which offer glimpses into our galaxy's past.
