Do the Plumes from Saturn’s Icy Moon Reach Down to Its Ocean?
The plumes erupting from Saturn's moon Enceladus may originate in slush in the moon's icy crust rather than its deep, subsurface ocean.
How Saturn's Moon Got Its Stripes
Astronomers have struggled to understand the origin of the parallel fractures on Saturn’s icy moon Enceladus, known as “tiger stripes,” from which water-ice spews into space. Now, a single explanation ties all the pieces together.
Potential Trouble for Life on Icy Moons
A lack of dry land on moons such as Europa and Enceladus might make it difficult to seed oceans with phosphorus, an element essential for life as we know it.
Enceladus: Hydrothermal Heating Confirmed
Astronomers have more evidence that the hidden ocean inside Saturn’s moon Enceladus is heated by hydrothermal activity.
Cassini Flies Through Enceladus's Plume
On October 28th, the Cassini spacecraft took its deepest dive through the water plume spewing from the south pole of Saturn’s moon Enceladus. It passed only 30 miles (50 kilometers) above the icy surface.
