In a story that sounds like the basis for a science fiction blockbuster, Professor Sabine Stanley, the Bloomberg Distinguished Professor of Earth and Planetary Sciences at Johns Hopkins University, demonstrates how studying Moon rocks has suggested a large number of meteor collisions in our solar system about four billion years ago—known as the Late Heavy Bombardment. See how this Moon event, which occurred during a concentrated time period of 200 million years, has implied that giant planets migrated during their formation—a possibility many scientists never considered.
