We cannot be certain (yet!) but current theories speculate that the moon Europa may be covered with ice, and that beneath the ice there might be oceans. There do appear to be ridges in the surface, which might be caused by cracks forming in the ice and then the liquid water beneath freezing as the ice sheets come back together.
