Enceladus covered with ice all over it, contains an ocean beneaths its surface.
Space is wonderful. Enceladus is one of the 62 moons orbitting Saturn. In 2005 the scientists observed plumes containing water vapor spewing from its south polar surface which gives evidence of a subsurface ocean under the moon.
Enceladus is a tiny moon which can say, represents 14% of our own Moon, yet it is the sixth largest moon of Saturn. It is believed that the water ocean on Enceladus is about 6 miles (10 kilometers).
See for yourself the water coming out of the moon's southern hemisphere :)
