Earth’s Water was Present before Moon-Forming Impact, Research Shows

Greenwood et al discovered that water was present on Earth at an early stage in its evolution and survived the giant impact, which formed the Moon. This is an artist’s depiction of a catastrophic collision between two celestial bodies; such an impact between the proto-Earth and Theia likely formed the Moon. Image credit: NASA / JPL-Caltech.

The high-energy impact about 100 million years after our Solar System formed, resulted in the two colliding planetary objects completely merging to create the Earth-Moon system we have now. An international research team led by an Open University scientist has discovered that most of Earth’s water was present before the catastrophic impact and not delivered later by small asteroids and comets as previously thought. This suggests liquid water can...
