Saturn’s icy moon may have an ocean

According to the Cassini orbiter, Saturn’s moon Encealdus may have an underground ocean of salty molten liquid. The moon shoots ice from geysers that burst from fissures in the moon as confirmed by Cassini, which swooped to within 21 kilometers of the surface. The icy geysers are responsible for Saturn’s E Rings.
