In an unlikely corner of our solar system, scientists have discovered evidence of what they believe is a subterranean ocean. The water means a tiny moon orbiting Saturn could be one of the few places in the solar system with the right ingredients for life.
The moon Enceladus is only 300 miles wide—it would fit between New York City and Charlottesville, Va. It’s a mini-world with a bright, icy, frigid surface, and it is just one of an astounding 62 moons orbiting the ringed planet. But it is not just a static, boring ice ball. Fractures on the moon’s surface—evocatively named “tiger stripes”—emit jets of frozen water that help form one of the bands in Saturn’s rings.
