Enceladus Bubbles (IMAGE)
Caption
The left panel shows the kilometers-thick icy crust believed to encapsulate Saturn’s moon Enceladus. Filling the crack is salty water with a proposed thin layer (shown orange) at its surface. The right panel shows that as gas bubbles rise and pop, they combine with organic material and get lofted into the spray.
