yeah i read up on it and all four giants (jupiter, saturn, uranus, neptune) have no "clear" surface: they all have a gaseous atmosphere on the surface, but when you go down, it goes above the critical point and therefore continuously changes into a liquid phase with no clear line in between. very deep inside, they all have cores made from rocks, but it's rather small compared to the total size of the planet.
