International research team investigated the isotopic composition of rocky planets in the inner Solar System — ScienceDaily

Earth and Mars were formed from material that largely originated in the inner Solar System; only a few percent of the building blocks of these two planets originated beyond Jupiter’s orbit. A group of researchers led by the University of Münster (Germany) report these findings today in the journal Science Advances. They present the most … Read more
