Saturn's South Pole Unveils a New Decagon Storm Cassini Didn't See
TL;DR Summary
A newly formed ten-sided jet around Saturn’s south pole has been confirmed by Hubble, a decagon Cassini never captured during its 13-year mission. The polygon appears to have formed after 2017 as Saturn’s long seasons brought the pole into view, and it strengthens near a southern anticyclone, suggesting the shape is actively forming rather than a long-lived relic.
