    This feature of hexagonal clouds on Saturn is very odd and scientists do not know the reason for its formation.  It was discovered during the 1980s when the Voyager flew by the planet.  No similar features have since been sighted anywhere in the Solar System.  The South pole of Saturn is known as having a strange rotating vortex and this image shows the North Pole with this mysterious cloud pattern.  This image was taken by the Cassini Spacecraft which reached Saturn in 2004.  This shows that the clouds have been active for over 20 years since the Voyager sighting.  This feature of the planet is very massive as four Earths could easily fit inside of it.
