New models from University of Zurich researchers suggest Uranus and Neptune may be rock-rich and convective rather than classic 'ice giants', offering fresh explanations for their odd magnetic fields and urging new missions.
Read More News Space 5 months ago Uranus and Neptune: Could They Be Rocky Giants, Not Icy? New models from the University of Zurich show Uranus and Neptune could be far rockier than assumed. The research broadens interior scenarios, links ionic water layers to odd magnetic fields, and argues for dedicated missions.
