Cassini Detects Enceladus Ocean: A Habitable World?
Saturn's moon Enceladus harbors a large, 6-mile deep underground ocean of liquid water, indicated by gravity measurements by the Cassini spacecraft and Deep Space Communications network.
- Radio measurements of Enceladus' gravity indicate an interior reservoir of liquid water, which may be connected to water jets gushing from fractures near the small moon's south pole.
- The newly reported finding validates the inclusion of Enceladus among the most likely places in our solar system to potentially host life.
