Dr. Maria Zuber, Griswold Professor of Geophysics and Vice President for Research at MIT, gave CIERA’s Fifth Public Lecture on Thursday, April 3rd. She introduced the audience to the “New Moon” that has been revealed by detailed maps of the Moon’s structure made by a pair of lunar satellites called GRAIL (Gravity Recovery and Interior Laboratory). These new maps have helped inform new models of how the moon as formed, and how the inner solar system evolved very early in the history of our Sun’s worlds. Professor Zuber also spent the day at Northwestern, speaking with administrators, faculty, and students.
