Ganymede is the biggest moon orbiting Jupiter and the largest satellite in the solar system. Reporting in The Journal of Geophysical Research: Space Physics, researchers describe a subsurface ocean on the moon that could be 60 miles thick. Geophysicist Joachim Saur, lead author on the study, tells us what this finding could mean for the search for life beyond our planet.
