The icy Jupiter's moon Europa could have subsurface ocean and possible rock iron core. Europa is the first icy moon of Jupiter.
Data from a previous NASA planetary mission, Galileo, have provided scientists evidence of what appears to be a body of liquid water just beneath the icy surface of Jupiter's moon, Europa. The data suggest that, not only is the volume of this Europan subsurface ocean similar to that of the North American Great Lakes, but also that there is significant exchange between the moon's icy shell and the ocean beneath.
The two geological terrain pictures above, where taken by Galileo spacecraft called "Chaos Terrain". The brown texture material is called "matrix" and you can see the large icebergs in both of the images.
