An article published in the journal “Nature Geoscience” describes a research that provides evidence of the existence of large amounts of water in ancient volcanic deposits on the Moon. Ralph E. Milliken and Shuai Li of Brown University used data collected by the Chandrayaan-1 space probe’s Moon Mineralogy Mapper Spectrometer to locate the water, perhaps formed after the collision between a planet and the primordial Earth that led to the Moon’s formation.
