The scientists have long held that the various seas on the moon were dry. But a recent study published in the Nature recently proves the assumption wrong. In this study, geologist Alberto Saal and his team of researchers from the Brown University have mentioned that they have the proof of water molecules in pebbles that have been retrieved by Apollo missions of NASA. Their finding signals to the fact that there could be water deep within the surface of the moon.

This finding also holds a lot of significance as it has the potential to greatly alter the understanding of the moon, which is the closest celestial body from earth, as well as our own. There may also be a more immediately practical application. If there is water on moon then it could prove vital for lunar missions, says Alberto Saal. He then adds that people could get the water, whereas use the hydrogen for energy purposes. It is also believed that the pebbles that have been retrieved from the moon were scattered by lunar volcanoes that erupted three billion years back.
