Ocean Detected Inside Enceladus

Article excerpt

The Cassini spacecraft's tour of Saturn has been one of NASA's most successful planetary missions. The spacecraft's amazing discoveries and images have revolutionized our knowledge of the ring world and its moons. The spacecraft has recently uncovered evidence that Saturn's moon, Enceladus, harbors a large underground ocean.

One of Cassini's major highlights was the 2005 discovery of water- ice geysers erupting from the surface of Saturn's moon Enceladus. This small moon is only one-seventh the size of Earth's moon. The geysers, which jet out at a distance three times the diameter of Enceladus, shoot particles into Saturn's expansive ring system. Based on this discovery, scientists believe that liquid water may be found just beneath the surface of Enceladus. New data from Cassini on Enceladus' gravity field support the theory that an ocean is hidden inside the moon.

Gravity measurements suggest to scientists that a large ocean about 6 miles deep lies beneath an ice shell about 19 to 25 miles thick. …
