On icy moon Enceladus, expansion cracks let inner ocean boil out

In 2006, the Cassini spacecraft recorded geyser curtains shooting forth from "tiger stripe" fissures near the south pole of Saturn's moon Enceladus—sometimes as much as 200 kilograms of water per second. A new study suggests ...

Ocean currents predicted on Enceladus

Buried beneath 20 kilometers of ice, the subsurface ocean of Enceladus—one of Saturn's moons—appears to be churning with currents akin to those on Earth.

Researchers model source of eruption on Jupiter's moon Europa

On Jupiter's icy moon Europa, powerful eruptions may spew into space, raising questions among hopeful astrobiologists on Earth: What would blast out from miles-high plumes? Could they contain signs of extraterrestrial life? ...

The habitability of Titan and its ocean

Saturn's largest moon, Titan, is a hotbed of organic molecules, harboring a soup of complex hydrocarbons similar to that thought to have existed over four billion years ago on the primordial Earth. Titan's surface, however, ...

Gas insulation could be protecting an ocean inside Pluto

A gassy insulating layer beneath the icy surfaces of distant celestial objects could mean there are more oceans in the universe than previously thought. Computer simulations provide compelling evidence that an insulating ...

Europa's ocean ascending

This animation demonstrates how deformation in the icy surface of Europa could transport subsurface ocean water to the moon's surface.
