Saturn Moon’s Geysers Explained

Scientists have a new theory to explain the ice-spewing geysers on Saturn's moon Enceladus.

The motion causes the moon's huge ice sheets to grind together, producing fault lines on the surface that are likely places where Enceladus' ice sheets are opening and closing.
