Yes. Scientists have identified a giant 10-sided atmospheric wave, known as a decagon, encircling Saturn's south pole.
The published research and observations from the NASA/ESA Hubble Space Telescope show that the pattern sits within a powerful jet stream and extends through multiple atmospheric layers. Researchers traced signs of the feature in Hubble observations dating back to 2023.
Scientists do not yet know exactly when the decagon formed, what caused it or how long it will persist. Continued observations will determine whether it becomes stable like Saturn's long-lived northern hexagon or continues to evolve.
Key takeaway
Saturn now has a documented 10-sided atmospheric pattern in its southern hemisphere, but its origin and longevity remain uncertain.

Not yet. The LZ experiment recorded one unexplained event that could involve dark matter, but it falls short of the threshold for a confirmed discovery.
