Constant gusts of particles from the sun may be creating water molecules on the moon, a new NASA-led experiment hints.
Scientists have detected traces of water molecules — as well as hydroxyl (OH) molecules, a component of water — on the surface of the moon through multiple space missions. The source of this water has long been a mystery, though some theories suggest volcanism, outgassing from deeper in the lunar regolith (the combination of rock and dust on the surface of the moon), and bombardment by tiny meteorites.
