An article published in the journal “Proceedings of the National Academy of Sciences” describes a research on the presence of water on the Moon. A team led by the geochemist James M. D. Day of the University of California at San Diego examined amounts and compositions of zinc, chlorine and lead isotopes in a lunar rock concluding that water and other volatile compounds evaporated very early in the Moon’s history. This contradicts a research published only a few weeks ago in which it’s argued that ancient Moon volcanic deposits contain large amounts of water.
