Jupiter's moon Europa just got even cooler
The more they look at other worlds in the Solar System, the more scientists discover that Earth isn't as special as we earthlings like to think. Our planet has active volcanoes — but so does Jupiter's moon Io. We have geysers — and so does Saturn's moon Enceladus. We have lakes, rivers and rain, and so does Titan, another moon of Saturn's.
