WHY DO SATURN HAS A HEXAGON ON ITS TOP??


Saturn is the most beautiful planet in our solar system and personally, it is my favorite planet of all time. When you go near to Saturn you can see some stupendous and weird activities that are happening in that gas giant and one of the weird things about Saturn is it has a hexagonal storm in its north pole, wait what? Really? Yes it has, storms are very common on our earth even on other planets like Venus, Mars, and Jupiter but nothing looks like a perfect polygon as same as that is in Saturn but why it has? because storms in Saturn are good at maths, just kidding !!! no that’s not the answer then what is the real reason? 

Ok for that let's start from the beginning, Saturn’s entire north pole was implied when the Voyager spacecraft flew by the planet in November of 1980, Then Cassini spacecraft arrived in Saturn’s orbit in 2004, but wasn’t able to take images of that region until 2007. Stunning images showed the hexagonal structure in detail which is in the north pole and the hexagon extended much deeper than scientists previously expected, with initial estimates reaching 100 km But the new model created by Yadav and geophysics professor Jeremy Bloxham suggests the storm could be thousands of kilometers deep. While the south pole of Saturn also has a large storm, it looks more like a hurricane with a giant eye but not in a hexagon. For scientists these data first looks uncanny but after a lot of researches and simulations now we have a good idea of why this thing occurs, at the center of the hexagon at the north pole, has a very robust vortex and where the fast-moving winds of that vortex interacts with the slow-moving winds further away and they start to mix together and forms hurricanes, after that, the hurricanes naturally space themselves out and these push the jet streams(Jet streams are fast flowing, narrow, meandering air currents in the atmospheres of some planets, including Earth) a little towards the north and this gives us the straight edges of the hexagon. 

For visualization purpose imagine a big rubber band surrounded by a bunch of small rubber bands. 

Then squeeze the entire thing from the outside and That the big rubber band is going to be compressed by some centimeters and form some weird shape with a certain number of edges.

That’s basically the physics of what’s happening. We have these smaller storms and they’re basically pinching the larger storms at the polar region and since they have to coexist, they have to somehow find a space to basically house each system.

By doing that, they end up making this polygonal shape and even we also, re-create that polygonal shapes in labs not only hexagon but from triangle to an octagon.
