Back in 2007 a gigantic hexagonal weather pattern was observed forming over Saturn’s north pole during a storm (see still image below taken by the Cassini spacecraft). The weather pattern is approximately 15,000 miles across (almost twice the diameter of the earth) and has held its shape since astronomers first discovered it 26 years ago via the Voyager space probe. These patterns have been observed in the past by anyone who was able to spin a bucket of water (dating all the way back to Isaac Newton) but none as epic in scale as Saturn’s Hexagonal Storm have ever been witnessed before. Below is a highly-controlled spinning centrifuge demonstration which creates the same pattern with some beautiful results.
