Erik Hauri will be delivering this year’s Carnegie Evening Lecture on 5 May. His talk, entited “Water in the Moon’s Interior: Truth and Consequences,” will discuss ion microprobe measurements of volcanic glass from the Moon that have revealed, for the first time, the presence of water in magmas erupted from the lunar interior billions of years ago. As the Moon has somehow retained water after its birth from giant impact, Hauri writes in his abstract, “...the consequences for the formation of the Earth-Moon system are convincing and compelling.” Hauri and colleagues first presented research on this topic in the July 2008 issue of Nature.
