NASA’s OSIRIS REx samples from asteroid Bennu revealed simple sugars and gum like organic molecules. These compounds formed through chemical reactions on dust grains exposed to radiation in space.
Astronomers have found a planetary system that seems to have formed inside-out. While most systems, like our own, have rocky planets closest to their star and gaseous ones further out, the LHS 1903 system has a rocky world at its edge, challenging established models of formation.
