Found this story and thought it was bizarre and really intriguing. Natural things like this don't normally come in shapes like this, it looks to me like something is CAUSING it to be that shape - maybe a MASSIVE (MASSIVE!!) hexagonal object, intelligently created?
Cassini Images Bizarre Hexagon on SaturnMarch 27, 2007
Pasadena, Calif. -- An odd, six-sided, honeycomb-shaped feature circling the entire north pole of Saturn has captured the interest of scientists with NASA's Cassini mission.
NASA's Voyager 1 and 2 spacecraft imaged the feature over two decades ago. The fact that it has appeared in Cassini images indicates that it is a long-lived feature. A second hexagon, significantly darker than the brighter historical feature, is also visible in the Cassini pictures. The spacecraft's visual and infrared mapping spectrometer is the first instrument to capture the entire hexagon feature in one image.
