Take a look at this beautiful movie image of Saturn taken by NASA:

This nighttime movie of the depths of the north pole of Saturn taken by the visual infrared mapping spectrometer onboard NASA’s Cassini Orbiter reveals a dynamic, active planet lurking underneath the ubiquitous cover of upper-level hazes. The defining feature of Saturn’s north polar regions–the six-sided hexagon feature–is clearly visible in the image.

“Who built that hexagon on top of Saturn?” one might ask.  No one built it.  It’s a self-organized pattern.  And the area of the hexagon is large enough to fit four earths.

This is a very strange feature, lying in a precise geometric fashion with six nearly equally straight sides,” said Kevin Baines, atmospheric expert and member of Cassini’s visual and infrared mapping spectrometer team at NASA’s Jet Propulsion Laboratory, Pasadena, Calif. “We’ve never seen anything like this on any other planet. Indeed, Saturn’s thick atmosphere where circularly-shaped waves and convective cells dominate is perhaps the last place you’d expect to see such a six-sided geometric figure, yet there it is.

But this striking pattern is merely one of the huge numbers of beautiful self-organized patterns one can find in our universe.  In Dynamic Patterns: the Self Organization of Brain and Behavior (1997), J. A. Scott Kelso describes the mysterious-seeming emergence of such dynamic patterns:

Patterns in general emerge in a self-organized fashion, without any agent-like entity ordering the elements, telling them when and where to go . . . [S]ystems that are pumped
