It was a theory that the Moon had many seas but all of them are dried up.But it is now proved wrong. In a study published today in Nature, researchers led by Brown University geologist Alberto Saal found evidence of water molecules in pebbles retrieved by NASA's Apollo missions.The findings point to the existence of water deep beneath the moon's surface,transforming scientific understanding of our nearest neighbor's formation and, perhaps, our own."Water is important for lunar missions. People could get the water and use the hydrogen for energy," said Saal.
The pebbles were scattered by lunar volcanoes that erupted three billion years ago, when the Moon was still a cooling hunk of magma cast into orbit by the collision of a Mars-sized asteroid with the Earth.
