Here is a recent article in space.com (I tried to link to this a few days ago, but it disappeared from the space.com archives...today it's back) about how Jupiter may have a much bigger core (14-16 Earth masses of rock!) than previously proposed. Previous predictions ranged from a core of 7 Earth masses of rock to no core at all. Juno should help nail down the absolute size of the core, and therefore, whether a rock core was required for the initial accretion. Which came first: gas or rock? And if rock is required to initiate accretion of gas giants... what about stars? -the other Doug (This discussion was originally in the Juno thread but was moved to a separate topic - moderator) -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain
