Are Uranus and Neptune Really Ice Giants?

Scientists are challenging the long-held view of Uranus and Neptune as ice giants after advanced computer simulations revealed they may contain vast magma oceans of iron and silicates beneath their atmospheres.

The new model could explain the planets' unusual magnetic fields and internal heat, while offering fresh insights into the mysterious sub-Neptune exoplanets that dominate our galaxy. Although only one spacecraft has ever visited these distant worlds, the findings strengthen the case for future missions to uncover their true nature.
