A Sixth Cyclone Has Joined the Configuration of Circumpolar Cyclones at Jupiter's South Pole This composite visible-light image taken by the JunoCam imager aboard NASA's Juno spacecraft on Nov. 3, 2019, shows a new cyclone at Jupiter's south pole has joined five other cyclones to create a hexagonal shape around a large single cyclone.A series of JunoCam images from Juno's 23rd close pass by Jupiter (Perijove 23) on Nov. 3, 2019 has revealed a sixth circumpolar cyclone in the cluster around Jupiter's south pole. A single cyclone is located close to the geographic south pole, and until now it has been surrounded by five cyclones. The five cyclones were discovered in images acquired early in the Juno mission, but their positioning was never a perfect pentagon. There was always a gap between cyclones 1 and 2 that varied in extent. Now number six has drifted into that gap, forming a nearly-perfect pentagon. The new cyclone had been observed previously nearby. / Credits: NASA/JPL-Caltech/SwRI/MSSS/JunoCam
