Join host Beth Johnson and guest Dr. Sam Courville, lead author of a new study on Ceres, as they dive into the possibility that the dwarf planet may have had the energy needed to support habitability for much longer than once believed. Using data from NASA's Dawn mission, researchers uncovered evidence of persistent geologic activity, brine movement, and long-lived energy sources beneath Ceres' icy surface. Could this small world in the asteroid belt have been more habitable than we ever imagined?
