NASA CONFIRMED: Pluto’s Hidden Nuclear Heat May Be Keeping Its Ocean Alive

Deep beneath Pluto’s frozen surface, something remarkable may be happening. Despite temperatures around −232°C and almost no sunlight, evidence from NASA’s New Horizons mission suggests Pluto could be hiding a vast liquid ocean beneath its thick ice shell. In this video, we explore the radioactive heat inside Pluto’s rocky core, the possible role of ammonia as natural antifreeze, and the mysterious gas-hydrate layer that may help trap heat underground. We’ll also examine the geological clues—ancient fractures, Sputnik Planitia, possible cryovolcanoes, and Pluto’s companion Charon—that reveal just how active this distant world may be. And then comes the bigger mystery: Was Pluto born with an ocean, and could other icy worlds in the Kuiper Belt be hiding oceans of their own? Watch until the end to discover why Pluto may be far more dynamic than scientists once imagined.
