This is the week for gazing up at the moon floating serenely in the night sky and imagining cataclysmic interplanetary collisions. Picture a Mars-sized planet slamming into the Earth about four-and-a-half billion years ago, injecting its iron core into our planet and sending a couple of quintillions of tons of vaporized mantle rock into orbit, where it forms a ring that re-condenses into the Man in the Moon. Planetary scientists at the Washington University at St. Louis (WUSTL) and Scripps Institution of Oceanography have supplied a key piece of evidence supporting just that giant-impact scenario of lunar formation—continuing the evolution of a 1975 conference-room conjecture into the leading explanation of selenic cosmogony. (The 1975 date is a little artificial. The idea that the moon is an offspring of Earth has emerged many times over the centuries. The 1975 incarnatio...
