Story summary

A new study by researchers from the University of Zurich suggests Uranus and Neptune may be rockier than believed, challenging classification as ice giants.
Researchers developed a hybrid model to analyze the planets' interiors.
The model indicates the cores may have high rock-to-water ratios.
The model suggests convective regions with ionic water could explain the planets' magnetic fields.
Lead author Luca Morf says Voyager 2 data are insufficient.
