A multi-institutional team of planetary scientists has learned more about the early composition of the solar system by studying a meteorite named Northwest Africa 14250. In their study, published in the journal Science Advances, the group used a scanning tunneling microscope to learn more about the isotopic makeup of clasts inside the sample.
