Scientists discover moon is shrinking

The moon is shrinking because of clashing tecton - ic plates triggering moonquakes, according to new research.

Earth-style quakes are wrinkling it “like a raisin” – creating step-like cliffs called “scarps” Each is roughly ten yards high and a few miles long – making them resemble a giant stairway on the lunar surface. They were first discovered more than 50 years ago by the Apollo astronauts, but analysis has shown some are more recent.

Nasa hopes to return to the moon in the next few years.
