I definitely wasn't supposed to be doing this this afternoon, but ... 🤷♂️🙂
A time lapse movie of the northern hemisphere of Saturn, showing a full rotation of the famous polar hexagon, a very cool fluid dynamics phenomenon in the planet's atmosphere 🪐🐻❄️

1. A time lapse movie showing the northern hemisphere of Saturn rotating over a 12.5 hour period. There are atmospheric bands at lower latitudes, with small spots and storms too, and then close to the north pole, there is a giant hexagonal structure in the atmosphere. At its centre is a large vortex. The rings of Saturn are seen above the planet and the latter casts a shadow on the rings to the left. The data have been given a silver blue tint, even though they are original monochrome.
