The Moon is more metal than we thought

The Moon is more metal than we thought, scientists have said.
The discovery could challenge our understanding of how it was formed, the researchers claim, after discovering new information from data sent back by a Nasa craft sent to visit the Moon.
For a long time, scientists have debated how the Moon was formed. The most popular story suggests that it was created after an object the size of Mars hit the Earth, sending what is now the Moon off into orbit.


But the subsurface of the Moon is more rich in metals than previously thought, suggesting that may not be true.
