Bruchstück des Stubenberg-Meteoriten
In der Meteoritenforschung untersuchen wir die Entstehung des Sonnensystems vor 4,5 Milliarden Jahren. Meteorite, interplanetarer Staub und durch Raumsonden zur Erde beförderte Proben dokumentieren die Prozesse, die zur Bildung der planetaren Kleinkörper des Sonnensystems geführt haben. Diese wiederum lieferten das Baumaterial der Erde und die Grundlagen des Lebens, so zum Beispiel Wasser. Die Untersuchung von Meteoriten, die von Großasteroiden, dem Mond oder dem Mars stammen, liefern direkte Informationen über frühe Prozesse, die durch teleskopische Beobachtungen oder Raumsonden im Allgemeinen nicht zugänglich sind.
