This document is subject to copyright. It was named after the river Muonio, at the border between Sweden and Finland, above the arctic circle, where it was discovered. This "rotten-peanut-butter-meteorite paste" was then dissolved with acid, until only the presolar grains remained. Drouard says this terrestrial crop of meteorites in the Atacama can foster more research on studying meteorite fluxes over large time scales.

"It starts with crushing fragments of the meteorite down into a powder ," explains Jennika Greer, a graduate student at the Field Museum and the University of Chicago and co-author of the study. By measuring how many of these new cosmic-ray produced elements are present in a presolar grain, we can tell how long it was exposed to cosmic rays, which tells us how old it is.
