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.
