Hubble reveals mysterious 10-sided pattern swirling at Saturn's south pole
x/hubble-space-telescope
— 3d
Astronomers have identified a giant 10-sided decagon in Saturn’s southern atmosphere, likely forming between 2017 and 2023 and continuing to evolve, with sides surpassing 10,000 miles. The feature, observed via Hubble and ground-based telescopes and published in Science Advances, drifts eastward about 6 mph and challenges the view that Saturn’s north-pole hexagon is unique by revealing a more complex, dual-pole meteorology.

So the north pole gets a tidy hexagon and the south pole shows up with a decagon like it's trying to one-up its sibling.
