New Model Recasts Uranus and Neptune as Magma-Ocean Giants
TL;DR
A UC-led study proposes Uranus and Neptune may harbor well-mixed magma oceans with dissolved hydrogen beneath a hydrogen-dominated envelope, suggesting they’re magma-ocean giants rather than ice giants and potentially explaining their densities. The model, submitted to The Astrophysical Journal, challenges the traditional three-layer interior picture and could inform the study of sub-Neptune exoplanets, though the idea remains under debate without a dedicated mission to these distant planets.
