A team of researchers at the University of Oxford have uncovered crucial evidence for the origin of water on Earth. Using a rare type of meteorite, known as an enstatite chondrite, which has a composition analogous to that of the early Earth (4.

The chemical composition of a meteorite that was built much like early Earth shows evidence of ample hydrogen necessary to form water.
