Washington, Nov 26 : Computer simulations have indicated that Jupiter has a rocky core, surrounded by layer of ice, that is more than twice as large as previously thought.
The simulations have been developed by a geophysicist at the University of California, Berkeley, who simulated conditions inside Jupiter on the scale of individual hydrogen and helium atoms.
The simulation predicts the properties of hydrogen-helium mixtures at the extreme pressures and temperatures that occur in Jupiter''s interior, which cannot yet be studied with laboratory experiments.
