A Piece of the Moon

After visiting the Museum of Modern Art yesterday, I went to the Hayden Planetarium for a lecture on the Core of the Moon.  The speaker, Ben Weiss, is a Planetary scientist at MIT, and he talked about the nature and history of the Moon's core.  It was a terrific lecture, and at the end he mentioned that he had brought a piece of Moon rock with him, and we could all see it out in the lobby.  So that's what he is doing here.  I love that someone illuminated the rock with a really bright LED flashlight, and so the rock itself appears to have some supernatural glow to it.  You would never know what is going on here, if I didn't describe what was happening.
