Uranus and Neptune are hiding something big beneath the blue

New research from the University of Zurich challenges the long-held belief that Uranus and Neptune are "ice giants," revealing these planets could actually contain far more rock than previously assumed. Using advanced simulation techniques that combine physics-based and empirical modeling approaches, scientists found that both planets could be either water-rich or rock-dominated structures, fundamentally questioning current planetary classifications and highlighting the need for dedicated missions to determine their true composition.
