Huge Asteroid Hits Moon and Leaves Rare Crater

A massive asteroid has crashed into the Moon in a rare event spotted by a NASA spacecraft. Scientists call the impact a once-in-a-lifetime or once-in-a-century moment. The space rock that hit the lunar surface is larger than St Paul's Cathedral and about the size of a six-storey building. This powerful crash left a brand new, giant crater on the Moon that was recently found by NASA's Moon Orbiter. A NASA scientist made the chance discovery, which has quickly become a major talking point among space researchers.
