Hubble detects rare 10-sided atmospheric wave at Saturn's south pole

NASA's Hubble Space Telescope has identified a massive 10-sided wave forming around Saturn's south pole, with early signs of the pattern traceable to 2023. The structure is embedded within a powerful jet stream and spans multiple layers of the planet's atmosphere. The discovery comes after decades of scientists searching for a southern equivalent to Saturn's well-known northern hexagonal storm pattern. Unlike the northern hexagon, which was already fully formed when first observed, this southern wave offers a unique opportunity to study a major atmospheric feature as it develops. Researchers say the finding provides valuable new insight into the complex atmospheric dynamics of Saturn.
