Man in the Moon's cataclysmic birth revealed

Shock waves from ancient lunar impacts may be responsible for creating the Earth's single most famous face - the "Man in the Moon".

People have long interpreted a series of dark patches on the Moon's surface as a human face but no one knew how they formed. Now, scientists at Ohio State University, US, appear to have solved the mystery by creating a topographical model of the Moon and mapping gravity signatures of rocks all the way to the core.
