Sunny parts of the moon contain water

摘要

Past observations suggest there's water on the moon. New telescope observations conclude those findings hold water. Spacecraft have seen evidence of water ice in permanently shadowed craters at the lunar poles, as well as hints of water molecules on the sunlit surface. But water sightings in sunlit regions have relied on detection of infrared light at a wavelength that could also be emitted by other compounds containing hydrogen and oxygen.
