00:00Saturn just got a whole lot stranger.
00:02Astronomers using NASA's Hubble Space Telescope have discovered
00:05a giant ten-sided cloud pattern circling the planet's south pole,
00:10something scientists have never seen before in that hemisphere.
00:13This newfound decagon stretches about 104,000 miles across,
00:17with each of its ten sides measuring more than 10,000 miles long,
00:21making it even bigger than Saturn's famous six-sided hexagon at the north pole.
00:26First spotted by the Voyager spacecraft back in the 1980s,
00:30researchers believe the decagon may have formed sometime between 2017 and 2023.
00:36While Saturn's south pole was tilted away from Earth and completely out of view,
00:40lead researcher Agustin Sanchez-LaVega says the discovery was a total surprise,
00:45and it proves the hexagon isn't as unique as scientists once thought.
00:49The structure moves incredibly slowly,
00:52taking about 800 days just to complete one rotation around the planet.
00:56Scientists say it could still be evolving,
00:58and they're hoping future observations will help solve the mystery
01:01of what's actually driving these strange geometric wind patterns on the ringed giant.
