Well, in space water starts to boil away immediately so you would need a gas tight container which don't typically happen in nature in sizes that would allow internal currents to develop.

Earth is a (reasonably) gas tight container filled with flowing liquid (lava propelled by convection currents). Europa (the moon) is a reasonably gas-tight container filled with water under an ice sheet. Of course Earth also has appreciable gravity. The real problem isn't that nature produces no gas tight liquid-filled containers, it's that gravity is the primary mechanism by which things are naturally created in spa…

https://en.m.wikipedia.org/wiki/Saturn's_hexagon > Saturn's hexagon is a persisting hexagonal cloud pattern around the north pole of the planet Saturn, located at about 78°N.[1][2][3] The sides of the hexagon are about 14,500 km (9,000 mi) long,[4][5][6][7] which is more than the diameter of Earth[8] (about 12,700 km (7,900 mi).

Why do the two photos at the top of that article look so weird? They look like 3D renders almost. Is that what it actually looks like to the eye too, if one looked at Saturn from a spacecraft orbiting around it?

I walk home most work nights and cross the Presumpscot River on my way. It adds about 20 minutes to go up to that end of town and see it. I did that a couple times last year, and will be doing so this coming Tuesday (since Monday is MLK day). Thankfully the weather will be mostly below freezing until then, although it will go up to 37 today. I think its the combination of the single digit nights which allow ice to fo…
