Nasa team sees explosion on Moon

Nasa scientists have witnessed a rare explosion on the Moon, caused by a "meteoroid" slamming into it. The blast was equal in energy to about 70kg of TNT and was seen near the edge of Mare Imbrium (the Sea of Rains). The object that hit the Moon was probably part of a shower of "taurids" which peppered Earth in late October and early November.
Understanding lunar impacts could help protect astronauts when Nasa sends humans back to the Moon.
