Discovered the silica (SiO2) mineral quartz in a primitive meteorite

A team of researchers from Waseda University, the Graduate University for Advanced Studies, the University of Hawaii at Manoa, Harvard University, and the National Institute for Polar Research discovered the silica (SiO2) mineral quartz in a primitive meteorite, becoming the first in the world to present direct evidence of silica condensation within the solar protoplanetary disk and coming a step closer to understanding solar formation and evolution.
