'Decagon' at Saturn’s South Pole? After the long-lived 'hexagon' at its north pole, astronomers spot a mysterious 10-sided atmospheric wave in the planet’s southern hemisphere - Here’s what we know so far

Astronomers have discovered a giant, evolving ten-sided atmospheric wave near Saturn's south pole. This striking geometric feature was identified using Hubble Space Telescope and ground-based observations. Unlike Saturn's stable northern hexagon, this southern decagon appears to be strengthening and evolving. Researchers are now closely watching this developing atmospheric pattern to understand its origins. The discovery offers a unique opportunity to study planetary atmospheric circulation and wave development.
