A giant 10-sided wave is emerging around Saturn’s south pole, Hubble observations show

{}Saturn's south pole reveals a giant, evolving 10-sided atmospheric wave. Hubble telescope observations trace subtle signs of this pattern back to 2023. This newly identified feature is embedded in a powerful jet stream and extends through multiple atmospheric layers. Scientists have searched for a southern counterpart to the northern hexagon for decades. This discovery offers a rare chance to observe a major atmospheric pattern developing in real time.
