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

Can anyone give n example of an exagonal natural formation like this on earth?

According to this source we have:

External source:
The hexagon spans nearly 25,000 kilometres – the width of two Earths – and appears to be a clearing in the clouds that extends at least 75 km below the planet's visible cloudtops.
...
This is a very strange feature, lying in a precise geometric fashion with six nearly equally straight sides," says team member Kevin Baines of NASA's Jet Propulsion Laboratory in Pasadena, California, US. "We've never seen anything like this on any other planet...
....
It's amazing to see such striking differences on opposite ends of Saturn's poles," says Bob Brown, leader of the Cassini visual and infrared mapping spectrometer at the University of Arizona in Tucson, US. "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.
Key words: "We've never seen anything like this on any other planet" <-- Kevin Baines of NASA's Jet Propulsion Laboratory in Pasadena.

Any thoughts?
