This is the most recent composite image of Saturn based on Cassini probe photos. On top of the planet, a blue-tone hexagon is visible. What we're seeing is the center of a huge polar vortex that spins on the north pole of Saturn.
Beautiful Saturn hides violent and tumultuous structures.
First observed by Voyager 1 and 2 probes in the early 80, this complex structure extends for nearly 25 thousand kilometres and forms a hexagonal pattern easily recognizable in images taken in infrared wavelengths.
As far as it is known, this form results of a standing hexagonal wave of cyclonic clouds, each side about 14 000 miles long (Earth diameter - 12 700 miles).
No one knows its origin, although it is probably related to the magnetic field resonance, of dodecahedric form. Similar patterns in swirling fluids have already been created in laboratory .
