Scientists have seemingly settled long-standing arguments about whether the components of Earth originated from the inner or ...

New research confirms Earth formed almost entirely from material in the inner Solar System, with Jupiter acting as a barrier to outer Solar System debris. Isotopic analysis of meteorites shows a close ...

Earth’s story may have hardened into place almost as soon as the Solar System began. That is the striking claim in new ...

Meteorite isotope research shows Earth's composition aligns almost entirely with inner solar system materials, with Jupiter's gravity likely blocking outer solar system debris. Published in Nature ...

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 ...
