ABC News: Yes, There Is Water on the Moon
Summary from United States, from articles in English
|
A new analysis of volcanic glass recovered from the moon decades ago found the rocks contain traces of the constituents of water, challenging a long-held notion that the moon is dry. (article 2)
Using a technique not available when Apollo astronauts collected the rocks in the early 1970s, scientists detected telltale signs of water trapped inside the pebblelike glass. (article 2)
The report, in the new issue of the journal Nature, may cause scientists to rethink theories on how the moon was formed. (article 2)
The pebbles, about the size of a period on this page, are made of magnesium-rich green volcanic glass and iron-rich orange glass that solidified moments after eruption. (article 2)
So researchers looked for one of those components, hydrogen, which would signal the presence of water. (article 2)
In a study published today in Nature, researchers led by Brown University geologist Alberto Saal found evidence of water molecules in pebbles retrieved by NASA's Apollo missions. (article 3)
The findings point to the existence of water deep beneath the moon's surface, transforming scientific understanding of our nearest neighbor's formation and, perhaps, our own. (article 3)
Their discovery suggests that water was present deep within the moon when the pebbles were formed during violent lunar eruptions 3.3 billion to 3.6 billion years ago. (article 1)
