The rare fossil meteorites are now on public exhibit at the Field Museum in the Main Hall (Stanley Field Hall next to Sue) extended until April 2015. After that they will be incorporated into a permanent exhibit that will open end of 2015. This is the first and only exhibit of fossil meteorites in the Western Hemisphere.

We may joke about looking for a needle in a haystack, but that’s nothing compared to searching for stardust in a foil! A new paper published in Science reveals that such work has led to the discovery of seven dust particles that are not only out of this world, they’re out of this solar system.

Field Museum meteorites help determine planetary core formation

A Field Museum research loan of iron meteorites that were made available to a group of researches in Germany led to the most accurate chronology to date of planetary core formation.

The group’s study finds that planetary cores formed very fast in geological terms, in about 1 million years after the first solids condensed in the solar system. For the first time the study finds also that cores of the parent bodies of different iron meteorites formed at different times. This was previously unknown and unresolvable because the analytical methods were not precise enough.

Dr. Philipp Heck, the Robert A. Pritzker Associate Curator for Meteoritics and Polar Studies and head of the Robert A. Pritzker Center, published a paper on atom-probe tomography of nanodiamonds from The Field Museum’s Allende meteorite in the journal Meteoritics & Planetary Science. This is the first application of the novel technique of Atom-Probe Tomography (APT) in the field of cosmochemistry.
