Saturn's South Pole Hides a 10-Sided Atmospheric Structure

Saturn's south pole just got a decagonal makeover

TL;DR

Astronomers spotted a 10-sided structure in Saturn's south pole atmosphere, suggesting conditions ripe for polygonal waves. The decagon, unlike the stable north pole hexagon, is a recent formation and could provide insights into atmospheric dynamics.

Astronomers have detected a 10-sided structure in Saturn's south pole atmosphere, marking a significant discovery in planetary science. This decagonal wave, unlike the stable hexagon at Saturn's north pole, is a recent formation and could reveal new insights into atmospheric dynamics and wave formation. The structure, confirmed through Hubble observations between 2023 and 2025, moves at a leisurely pace of around 10 kilometers per hour, embedded in one of Saturn's powerful eastward jet streams racing at 420 kilometers per hour. This discovery suggests that Saturn's southern subpolar jets can indeed produce polygonal waves, challenging previous assumptions. Scientists are now closely monitoring the decagon to understand its formation and evolution over time.
