Computer artwork of the interior of Europa, a moon of the planet Jupiter. This moon has a small metal core, possibly molten (orange), surrounded by a large mantle of rock (brown). On top of this sits a thick layer of solid ice. Finally, between this layer and the frozen surface there is probably a substantial underground ocean of liquid water.
