UPDATE: We regret to announce that the Spring Neighborhood Lecture Series has been postponed due to growing concerns over the spread of COVID-19. This difficult decision has been made after careful assessment of risks as determined by the CDC and WHO. Read more about our decision. 

Sarah Stewart
is a Professor at the Department of Earth and Planetary Sciences at the University of California, Davis.  She received her Ph.D. in Planetary Sciences from Caltech and is a recent recipient of a MacArthur Genius Prize for her work on planetary collisions and the discovery of synestias.  Stewart will talk about the accidental discovery of a new type of astronomical object, called a synestia, that may save the idea of a giant impact and forever change the way you think about the birth of our planet.
