resh evidence has been uncovered for the theory that our moon was created by a collision between Earth and a planet-sized object some 4.5 billion years ago. German scientists studied moon rocks gathered by astronauts nearly a half-century ago in the Apollo 11, 12 and 16 missions.
They say the results show Earth was hit by a huge object called ‘Theia’ which led to the moon’s formation. They analysed various kinds of oxygen atoms and found the moon rocks have a different makeup than Earth rocks do.
