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.
“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.”
The hexagon is similar to Earth’s polar vortex, which has winds blowing in a circular pattern around the polar region. On Saturn, the vortex has a hexagonal rather than circular shape. The hexagon is nearly 25,000 kilometers (15,000 miles) across. Nearly four Earths could fit inside it.
The new images taken in thermal-infrared light show the hexagon extends much deeper down into the atmosphere than previously expected, some 100 kilometers (60 miles) below the cloud tops. A system of clouds lies within the hexagon. The clouds appear to be whipping around the hexagon like cars on a racetrack.
“It’s amazing to see such striking differences on opposite ends of Saturn’s poles,” said Bob Brown, team leader of the Cassini visual and infrared mapping spectrometer, University of Arizona, Tucson. “At the south pole we have what appears to be a hurricane with a giant eye, and at the north pole of Saturn we have this geometric feature, which is completely different.”
The Saturn north pole hexagon has not been visible to Cassini’s visual cameras, because it’s winter in that area, so the hexagon is under the cover of the long polar night, which lasts about 15 years. The infrared mapping spectrometer can image Saturn in both daytime and nighttime conditions and see deep inside. It imaged the feature with thermal wavelengths near 5 microns (seven times the wavelength visible to the human eye) during a 12-day period beginning on Oct. 30, 2006. As winter wanes over the next two years, the feature may become visible to the visual cameras.
Based on the new images and more information on the depth of the feature, scientists think it is not linked to Saturn’s radio emissions or to auroral activity, as once contemplated, even though Saturn’s northern aurora lies nearly overhead.
The hexagon appears to have remained fixed with Saturn’s rotation rate and axis since first glimpsed by Voyager 26 years ago. The actual rotation rate of Saturn is still uncertain.
“Once we understand its dynamical nature, this long-lived, deep-seated polar hexagon may give us a clue to the true rotation rate of the deep atmosphere and perhaps the interior,” added Baines.

The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Cassini-Huygens mission for NASA’s Science Mission Directorate, Washington. The Cassini orbiter was designed, developed and assembled at JPL. The Visual and Infrared Mapping Spectrometer team is based at the University of Arizona.

I was thinking the other day if we are being visited by Aliens why do they not help us out and cause Karl Rove to have a heart attack while he is having sex. Then it hit me…..causing him to have a heart attack would be easy for them it is finding someone to have sex with him that they would find so damn difficult. Why it would take massive intervention in the minds of perhaps 3 billion people to find one that might consider it. And even then the person would probably be underage.
I think Saturn may be telling us ( or at least me ) something. Based upon the Scientist, Cleve Baxter’s, beliefs: all things in the Universe are related and perhaps communicate. I recall thinking about the shape, hexagon, for the past week. In fact, just around an hour before I heard about the new Cassini images, I was in deep thought about the molecular structure of the shape. This came after catching a climpse of many on the show Star Trek. Though I think it began several days ago when I caught myself in deep thought over the Honeycomb cereal. THEN, a few nights ago after buying a star/planet program for my computer, I caught my first real glimpse of the planet Saturn in the night sky barely above the horizon, ( I remained excited for days ). But more importantly I couldn’t stray from life reminding me of the shape until I read about the news of Saturn. Whoa ! Then it all seemed to fit together. I’m no more crazy than you aren’t. But at least I feel as thgough the timing of this discovery is cosmically perfect. It’s completely sane. Let’s keep up the sanity and our everflowing electrical energy open to what Saturn and the Universe may be trying to tell us.

P.S. This is not some stupid joke. I do antisipate the potential of my claim. We all ought to be open-minded.
If you can, please write me back with some thought on my experience.
Upon visiting the nasa website and reviewing additional photos, it became evident that there was a pattern. Note the concentric circles found in the atmospheric clouds around the hexagon. Could these patterns and the cause be the clue to the formation of the rings and possibly further help us to understand the force of gravity?
We should expect to see Starbuck any minute now.
If what we are looking at are cloud formations in a hexagon shape that remain stationary for 26years then this means. Some type of massive land based freuency generator is sending out a hexgon pattern to the upper atmosphere. This can not be true because almost everyone tells us that the only intelligent life,in our solar system, is on earth. It must be the Russians or Americans who did it because ET’s don’t exsist
