Researchers using advanced simulations have identified a remarkable state of matter deep within Uranus and Neptune where hydrogen and carbon atoms behave in unprecedented ways under extreme pressure and heat. This "superionic" hybrid phase—simultaneously solid and fluid—could revolutionize our understanding of how these distant planets generate heat and magnetism, opening new avenues for planetary science discovery.
