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.
