A research group at the University of Bayreuth has found a long-sought explanation for the apparent contradictions implicit in the composition of lunar and Martian meteorites. In cooperation with the German Electron Synchrotron (DESY) in Hamburg, the European Synchrotron Radiation Facility (ESRF) in Grenoble and research partners in Lyon and Vienna, the Bayreuth scientists led by Prof. Dubrovinsky were able to demonstrate how meteorites could contain within narrow spaces minerals whose formation conditions are quite different.
When asteroids or co...
