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.

      Reminds me of that old joke:

      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?"
      His host replies, "Oh, these guys have known each other for years, so long now that they know all their jokes. So, to save time , they numbered them."
      "Oh!" the visitor says.
      "Did you want to have a try at it?" says the host.

      With much trepidation, the visitor stands up and says, "96."

      Well, it brought the house down. Grizzled old men are rolling about, clutching their sides laughing, gasping for breath. This goes on for nearly ten minutes.

      "Wow! They really liked that one!" says the visitor.
      "I'll say!" said the host, wiping a tear from his eye, "They hadn't heard that one before!"

      Another related possibility is spherical harmonics, similar to what happens in the sun. The planet would be effectively resonating like a 3D drumhead. If that's true, there should be other points on the surface that exhibit similar phenomena.

      Maybe the solid core is acting like the agitator? Perhaps there are rougher features at the northern pole than there are at the southern, explaining why there is no southern hexagon. The article says the hexagon rotates at the same speed as radio emissions from Saturn, which they assume is the same speed as the core rotates.

      The curious thing, though, is that the south pole is very different -- almost looks like a human eye. I wonder what sort of rotational effect could cause such an asymmetry between north and south poles?

  11. It's a Dissipative Structure by vandan · · Score: 4, Interesting

    Fritjov Capra ( this guy's an absolute legend, by the way ) had an interesting section on hexagonal structures like these in his book, Web of Life. He was talking about Dissipative Structures, discovered by Ilya Prigogine.

    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. It was fascinating reading - thoroughly recommended for people interested in biology, physics, and philosophy.
