Astronomers Detect a 10-Sided Structure in Saturn's Atmosphere

Astronomers have discovered a 10-sided polygon structure swirling around Saturn's south pole, complementing the famous hexagon at its north pole that has been observed for over 40 years. The decagon was first spotted in 2024 in amateur astronomer images and confirmed through Hubble observations, suggesting that polygonal atmospheric waves are a common feature in Saturn's polar regions rather than isolated phenomena. This discovery indicates that conditions in Saturn's atmosphere naturally produce these geometric shapes, though the exact mechanism behind their formation remains unclear.
