When other planets do storms, they do 'em right. The Cassini spacecraft snapped photos of this monster thunderstorm on Saturn that's been raging for five months now, each lightning bolt packing 10,000 times more juice than it's Earthly counterparts. Jupiter's still got the illest storm in the solar system with it's almost four-century old Great Red Spot, but Saturn's storm's not too shabby — it's that blotch down in the lower right-hand part of the planet. That bright spot just below the rings? That's Saturn's moon Tethys looking way bigger than it should because it's in the foreground, just to give you a rough sense of scale. (from NASA)
