Although a simple, short sentence 'This finding means water is native to the moon,' the sentence is very important to the history of the Moon. This water, for the most part, did not come from impacts with asteroids, comets, and other celestial bodies. It was a part of the Moon when it first formed.
Francis McCubbin, the lead author of the study, stated, 'For over 40 years we thought the moon was dry. In our study we looked at hydroxyl, a compound with an oxygen atom bound with hydrogen, and apatite, a water-bearing mineral in the assemblage of minerals we examined in two Apollo samples and a lunar meteorite."
The study was published in the journal Proceedings of the National Academy of Sciences (PNAS).
Their PNAS article is entitled 'Nominally hydrous magmatism on the Moon.'
They state in the abstract to the paper: 'For the past 40 years, the Moon has been described as nearly devoid of indigenous water; however, evidence for water both on the lunar surface and within the lunar interior have recently emerged, calling into question this long-standing lunar dogma.'
