American researchers received data from the Juno probe, which explains the nature of Jupiter’s polar shine.

Apparently, the polar radiances at the poles of Jupiter generate non-dispersing electrons, as on Earth, and another type of interaction of charged particles.

Juno’s flight over the polar region showed that the electrons in the Jupiter’s atmosphere accelerated in the direction of Jupiter at energies up to 400,000 electron volts — which is 30 times higher than the largest polar eclips observed on Earth.

«At Jupiter, bright polar glare is caused by some kind of turbulent process of particle acceleration, which we do not understand very well yet,» explains lead researcher Barry Mouche of Johns Hopkins University at

When the electrons reached the poles of Jupiter, they were scattered with clouds of plasma existing in the upper layers of the atmosphere of the planet, and generated flashes of light and ultraviolet radiation. Because of turbulence, electrons are so much accelerated that in large quantities create dazzling flashes in the sky. A similar process occurs when some very weak polar shades appear on Earth.

At the moment, it’s just a work hypothesis, since researchers can not fully explain what’s happening. But at the moment, the turbulent acceleration hypothesis is the best explanation for Jupiter’s polar shine.
