The Field Museum will receive a high-quality meteorite from a fireball that exploded over California and Nevada last month. The 4.6-billion-year-old meteorite, donated by private collector Terry Boudreaux, is extremely rare and valuable to science. It weighs about one-third of an ounce (10 grams) and has been tentatively classified as carbonaceous chondrite.
Robert A. Pritzker Assistant Curator of Meteoritics and Polar Studies Philipp Heck and co-authors from the Max-Planck-Institute for Chemistry in Germany had their paper on the first isotopic analysis of sulfur-rich comet dust published in the April issue of the journal Meteoritics & Planetary Science. The dust was captured during a flyby of Comet Wild 2 by NASA’s Stardust Mission and returned to Earth.
