Cassini Images Show Activity on Saturn Moon
From Times Staff and Wire Reports
NASA’s Cassini spacecraft has found evidence that Saturn’s moon Enceladus is geologically active.
Recent images taken by the spacecraft show streams of fine icy particles rising from the moon’s south pole, suggesting they originated from warm zones in the region.
The discovery puts Enceladus in the class of geologically active moons with Jupiter’s Io and Neptune’s Triton. It’s unclear what causes the geologic activity, but scientists think it’s due to internal heating caused by radioactivity or tides.
