Astronomers using Hubble found a new roughly 104,000-mile-wide ten-sided storm forming at Saturn’s south pole, a geometric twin to the famous hexagon that has long circled the north

Astronomers have discovered a massive ten-sided storm pattern at Saturn's south pole using the Hubble Space Telescope. This 'decagon' mirrors the famous hexagon found at the planet's north pole, providing new insights into atmospheric physics.
Why it matters
The discovery challenges existing models of planetary atmospheric dynamics and suggests deeper, universal geometric principles in gas giants.
Saturn's symmetry breaks: a ten-sided storm now mirrors the planet's legendary hexagon, suggesting these geometric puzzles obey deeper physics we're only beginning to understand.
