Deep inside Neptune and Uranus, an exotic form of ice may behave nothing like ordinary ice. Researchers have created a new superionic phase under extreme conditions, where hydrogen can flow freely through a rigid oxygen structure, potentially helping explain the ice giants’ unusual magnetic fields. The discovery could reshape our understanding of what lies beneath their atmospheres. Thank you for listening to Bedtime Astronomy — your guide to the cosmos.
