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)
U.S. researchers have found evidence of water on the moon by studying glass pebbles picked up by NASA astronauts more than 30 years ago. (article 4)
The study, published in Nature on Thursday, means " the presence of water must be considered in models constraining the moon's formation and its thermal and chemical evolution the abstract said. (article 4)
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)

Most of the water in the magma vaporized into space, but traces may have drifted to the moon's cold poles, where they could remain as ice in shadowed craters. (article 1)
The glass beads from the magmas were bombarded with a stream of ions, and then the team analyzed the secondary ions emitted with a mass spectrometer. (article 1)
" We developed a way to detect as little as five parts per million of water said researcher Erik H. Hauri from the Carnegie Institution for Science. (article 1)
" We were really surprised to find a whole lot more in these tiny glass beads, up to 46 parts per million. (article 1)
" This suggests the very intriguing possibility that the moon's interior might have contained just as much water as the Earth's depleted upper mantle Hauri said. (article 1)
NASA, which funded the research, is planning to send the Lunar Reconnaissance Orbiter to the moon late this year. (article 1)
