Saturn Unveils a New 10-Sided Polar Polygon

TL;DR Summary
Astronomers using the Hubble Space Telescope have detected a new 10-sided polygon (a decagon) at Saturn’s south pole, adding to the planet’s famous north-pole hexagon. The pattern is a cloud-formed atmospheric feature, not a solid surface, likely shaped by waves and jet streams; researchers will continue monitoring with Hubble and JWST to understand its origin, duration, and how deep these structures extend.
