What NASA's Juno Found Inside Jupiter Broke a 60-Year-Old Model

For sixty years, every textbook showed Jupiter the same way: a dense, rocky core about ten times the mass of Earth, sitting compact at the center. Then NASA's Juno spacecraft arrived — and what it measured shattered the model. Using Doppler gravity science, Juno revealed that Jupiter's core is not compact at all. It is dilute — heavy elements dissolved and spread across nearly half the planet's radius, a diffuse zone holding the equivalent of 300 to 500 Earth masses. Not a core with clean edges, but a core that lost its boundaries entirely. In this video we break down how the compact core model was built, how Juno tested it, what the 2017 Nature data actually showed, and the leading theory that a giant impact billions of years ago shattered and mixed Jupiter's center forever. The mission is still running. The dilute core is still unexplained.    / @sciencedecoded   #Jupiter #Juno #SpaceScience
