1. WOW!!

2. Love the science. Very cool

3. Both amazing, and beautiful.

On Earth, hurricanes have been known to have a pentagonal shaped eye.

I've read that they could have square, ore even hexagonal eyes, but couldn't find an example.

Explanations for hexagon shape

An early hypothesis attributed the hexagon to Rossby waves.[21]

A hypothesis developed at Oxford University is the hexagon forms where there is a steep latitudinal gradient in the speed of the atmospheric winds in Saturn's atmosphere.[22] Similar regular shapes were created in a laboratory when a circular tank of liquid was rotated at different speeds at its centre and periphery. The most common shape was six sided, but shapes with three to eight sides were also produced. The shapes form in an area of turbulent flow between the two different rotating fluid bodies with dissimilar speeds.[22][23] A number of stable vortices of similar size form on the slower (south) side of the fluid boundary, and these interact with each other to space themselves out evenly around the perimeter. The presence of the vortices influences the boundary to move northward where each is present, and this gives rise to the polygon effect.[23] Polygons do not form at wind boundaries unless the speed differential and viscosity parameters are within certain margins and thus absent at other likely places, such as Saturn's south pole or the poles of Jupiter.

6. Wow! This is cool.

Found a short video about it.

9. I have become so skepticle.......

As AI get bigger, better and stronger, I wonder WHERE the AI and REAL start and stop.

That is all.
