Mikrometeorite und ihr Ursprung im Sonnensystem: Außerirdischer Staub zum Anfassen

open access: yesPhysik in unserer Zeit, EarlyView.
Mit einer Größe, die der Dicke eines Haares entspricht, sind Mikrometeorite kaum sichtbar für das bloße Auge. Dennoch werden sie seit etwa 150 Jahren gesammelt, und seit wenigen Jahren sogar auf unseren Hausdächern. Als Kostproben von Asteroiden oder Kometen stellen sie wertvolle Boten unseres Sonnensystems dar.
