New Scientist is carrying this story about a startling new discovery about Saturn's moon Enceladus. By using both visible and infrared cameras, the space probe Cassini has imaged gigantic water geysers erupting on its south pole. The problem is, they shouldn't be there, and scientists can't come up with a convincing explanation as to how they work (well, aside from the "water shoots out under pressure" bit).

Forget a ticket to California. Anyone got a ticket to Saturn? Round trip, of course.
