Gas giants more solid than thought

Even Jupiter appears now to have quite large rocky core, surrounded by an also thick layer of varied ices (water, methane, etc.) This structure seems similar to that of Saturn and not really different from that of Uranus or Neptune, just that these two have a much narrower atmosphere.

These conclusions are the result of a systematic modelling by scientists of the University of California and appears to be in very tight agreement with the measures taken by the Gallileo probe.
