Symposium—Earths, Moons, Mars, and Stars

152nd Annual Meeting of the National Academy of Sciences

Despite what the title of the symposium might suggest, the strong common theme of the talks in this symposium—change—highlights recent advances from different branches of the Earth and Planetary Sciences. Several presentations focus on changes on time scales corresponding to the age of the Solar System itself and their implications for habitable environments. The recent discovery of planets around other stars has realization that our own planetary system may have changed in ways not imagined a few years ago. Two presentations highlight the other extreme of the time scale by discussing our understanding of catastrophic changes, both locally as in the case of earthquakes and globally as in the case of the origin of our moon.
