Unusual vortices tied to Jupiter’s magnetic field may be driving massive formations of atmospheric haze close to the giant planet's poles.

Scientists have discovered Earth-sized dark UV spots at Jupiter's poles, likely caused by magnetically driven vortices concentrating hydrocarbon haze. These transient features, visible in ultraviolet light,

New research reveals that Jupiter’s magnetic tornadoes generate massive Earth-sized storms, visible only in ultraviolet light.

Magnetic vortices twisting down from Jupiter's ionosphere into its deep atmosphere cause giant, ultraviolet-absorbing polar anticyclones, each the size of our Earth.

Jupiter’s immense size–about 1,000 Earths could fit inside of it–and its swirling and jiggly Great Red Spot typically get most of the attention. Now, the planet’s northern and southern poles have entered the discussion.

The Great Red Spot is not the only Earth-sized atmospheric disturbance seen on Jupiter. That dramatic storm remains number one for size and power in the Solar System, but ultraviolet (UV) observations from Hubble have now revealed that Earth-size ovals of haze are being stirred up over Jupiter's polar regions.

While Jupiter’s Great Red Spot has been a constant feature of the planet for centuries, University of California, Berkeley, astronomers have discovered equally large spots at the planet’s
