Enceladus Moon

Why the Warm Ocean on This Moon of Saturn Could Be Perfect for Life

One of the most promising places to look for life beyond Earth just got even more tantalizing

Move over, Europa. It looks as though the most life-friendly habitat ever discovered outside of Earth is Enceladus—Saturn’s sixth-largest moon.

Astrophysicists working with NASA’s Saturn sweeping Cassini spacecraft have just announced that Enceladus has a warm ocean at its southern pole with ongoing hydrothermal activity—the first ever discovered outside of Earth. This new research, published in the journal Nature, builds upon last year’s discovery of the moon’s 6-mile-deep ocean, which is also believed to contain many of the chemicals commonly associated with life.

“We now have very strong evidence that there is a hot hydrothermal environment at the base of Enceladus’s ocean, perhaps like those where we believe life began on Earth,” says Jonathan Lunine, a planetary scientist at Cornell University who works with the Cassini spacecraft but was not involved in the new research. “This is yet another discovery in a series of really remarkable findings that have come one by one, to tell us that this may be the place to go look for life in the outer solar system.”
