A Common Origin for Lunar and Terrestrial Water? (1 of 1)

Caption

This is a backscatter electron image of a lunar melt inclusion from Apollo 17 sample 74220, enclosed within an olivine crystal. The inclusion is 30 μm in diameter. Skeletal crystals within the melt inclusion are a fine mixture of olivine and ilmenite. Dark area in the lower-left is an ion microprobe sputter crater. This image relates to a paper that appeared in the May 9, 2013, issue of Science Express, published by AAAS. The paper, by Alberto Saal at Brown University in Providence, R.I., and colleagues was titled, "Hydrogen Isotopes in Lunar Volcanic Glasses and Melt Inclusions Reveal a Carbonaceous Chondrite Heritage."
