Cassini Probes the Hexagon On Saturn

Riding with Robots sends us to a NASA page with photos of a little-understood hexagonal shape surrounding Saturn's north pole. "This is a very strange feature, lying in a precise geometric fashion with six nearly equally straight sides," said Kevin Baines, member of Cassini's visual and infrared mapping spectrometer team. "We've never seen anything like this on any other planet." This structure was discovered by the Voyager probes over 20 years ago (here's an 18-year-old note on the mystery). The fact that it's still in place means it is stable and long-lived. Scientists have no idea what causes the hexagon. It's nearly big enough to fit four earths inside — comfortably larger than Jupiter's Great Red Spot. The article has an animation of clouds moving within the hexagon captured in infrared light.

      A guy gets invited to a hunting lodge one evening, and on his arrival, everyone is having a few beers and taking it easy. Suddenly, one of them stands up and says, "27". Everyone has a bit of a laugh and they clap appreciatively. Another person stands and says, "48." Again this is met with laughter and a few guffaws.

      The visitor is perplexed and asks his host, "What's going on here?"

It isn't terribly out of the range of possibility that simple theories like these may be enough to explain a lot of this phenomenon. And, yes, polygonal eyewalls in real hurricanes can be very persistent, if the vortex itself doesn't change much and proper balances are maintained. On a planet like Saturn, I would imagine that things don't change too much even from year to year, so the whole pattern could persist for decades if unperturbed.

    In the experiment that was being described, a small dish of water was heated up uniformly from below. At a certain point, these hexagonal structures emerged. Hot water would rise from the bottom of the dish, travelling in a pipe directly through the middle of the hexagon ( forming a point in the middle that you could see ). When the water hit the surface, it spread out cooled, and then travelled back down to the bottom, creating the sides of the hexagon. Apparently they were getting multiple hexagons, and they were incredibly stable ... ie you could run a pen through them and disturb them, and they'd immediately revert to these perfect hexagons.
