What Lies Beneath Ceres | Dr. Samuel Courville

New evidence suggests that Ceres may still harbor subsurface brine, cryovolcanic activity, and internal heat sources capable of sustaining habitable environments. The discussion explores how radioactive decay, methanogenesis, and chemical energy could support life beneath its surface, what salt deposits reveal about ancient liquid water, and whether asteroids like Ceres could have delivered Earth’s oceans—and possibly life itself—featuring Dr. Samuel Courville with John Michael Godier.Links:https://www.science.org/doi/10.1126/sciadv.adt3283https://www.jpl.nasa.gov/news/nasa-ceres-may-have-had-long-standing-energy-to-fuel-habitability/https://www.seti.org/news/hidden-habitability-on-ceres-what-dawn-discovered-beneath-ceres-icy-crust/Podcast: hhttps://creators.spotify.com/pod/show/john-michael-godier/subscribeApple: https://apple.co/3CS7rjTMore JMG https://www.youtube.com/c/JohnMichaelGodierWant to support the channel?Patreon: https://www.patreon.com/EventHorizonShowFollow us at other places!@JMGEventHorizon
