Jupiter Has No Core: Why It Breaks Every Planet Model We Have | Cosmic Depth US

NASA's Juno mission has overturned decades of planetary science by revealing that Jupiter does not have a solid, compact core, nor is it gas all the way down. Instead, it possesses a \"diffuse core\"—a gradual gradient of heavy elements spanning half the planet's radius. This discovery, mirrored in Saturn, challenges existing models of how gas giants and exoplanets form.
