Secular Café: The Fountains of Enceladus

Secular Café Serious discussion of science, skepticism, evolution, pseudoscience, and the paranormal

The Fountains of Enceladus Mar 29th 2012, 01:07 Is it snowing microbes on Enceladus? Geysers at the poles of Saturn's moon Enceladus are spraying salt water into space- and possibly microbes, too. The Cassini spacecraft has returned fascinating pictures and data, showing multiple geysers. The source of the energy which powers these fountains is a mystery; although it's most probably a result of tidal flexing from the moon's orbit around Saturn, calculations show that the present orbit isn't sufficiently eccentric to generate the observed heat flow from the fountains. This could well be the place where we first detect extraterrestrial life!
