What do scientists think that's in the middle of Saturn?

Scientists believe that the core of Saturn is likely composed of a mixture of rock and ice, surrounded by a deep layer of metallic hydrogen and liquid hydrogen. The exact nature of the core is still a subject of research, but it's thought to be larger than previously estimated, possibly containing heavier elements. The extreme pressures and temperatures within Saturn contribute to the unique conditions present in its interior. Overall, the internal structure remains an area of active exploration and study.
