Collision with a Mars-Sized Body Delivered Carbon to Early Earth

Researchers propose that a planetary body the size of Mars crashed into early Earth, simultaneously delivering a mix of volatile elements necessary for life and creating the Moon. The hypothesis is based on a new study of how the presence of sulfur in a newly forming planet impacts whether carbon and nitrogen end up in the core or the mantle.
