We've known for some time that geysers on Saturn's moon Enceladus sprays water vapor that eventually finds its way to Saturn. But this striking image lets us see that water vapor spilling into space.
If you've ever visited Old Faithful and the other geysers at Yellowstone National Park, you've likely come away with two reactions. First, it's one of the most captivating sights in all of nature. Second, the place stinks like rotting eggs.
If you're tired of skiing on Earth, there's some perfect powder waiting for you, just 800 billion miles away. It's all thanks to Enceladus's amazing water geysers, some of which rain back down on the moon's surface as snow.
Dozens of nearly-imperceptible mini-earthquakes have made Yellowstone National Park tremble over the past few days - they might be early warning of an eruption so huge it buries half the U.S. under hot ash.
