Did a Comet trigger jets from Saturn's moon?

The geyser like jets spurting from Saturn's moon Enceladus have intrigued scientists who wonder whether they are evidence of life on the satellite.

But the latest intrigue around the jets is whether they arose courtesy comet collisions with the surface millions of years ago.

Recent photographs from the Cassini spacecraft have facilitated the process of examining the surface of the moon particularly at points around the geysers. Scientists have found ridges quite similar to those at the bottom of our ocean's, except the ridges on Enceladus are quite parallel and demonstrate gradual spreading.

Research is currently focusing on computer models to simulate the actions that may have preceded such ridges. A consensus seems to be forming on an impact that arose as a consequence of a comet crash. The ensuing surface changes may have created the structural and pressure changes that would engender such a phenomenon.
