Hubble Observations Show Ten-Sided Cloud Pattern at Saturn's South Pole
Recent Hubble Space Telescope observations of Saturn revealed a decagon, or ten-sided, cloud pattern surrounding the planet's South Pole [1]. A hexagonal, six-sided cloud formation at Saturn's North Pole has been documented since 1987, based on data gathered by NASA's Voyager spacecraft during their flybys of the ringed planet in the early 1980s [1]. The geometric boundaries may result from waves formed when fast-moving gas farther from the poles interacts with polar regions [1]. The image was featured in NASA's Astronomy Picture of the Day for September 8, 2026, which publishes a daily image with an explanation written by a professional astronomer [1].
