A water plume has been observed escaping from a moon of Saturn, with some reports specifically identifying the moon as Enceladus. The discovery has raised questions about the potential habitability of sub-surface seas on distant moons and may also provide insight into the origin of Saturn's rings. However, there is some uncertainty, as one outlet mistakenly reported the plume was seen on a Jupiter moon, while others have suggested that the moon's water jets may not be as previously thought.
