An article published in the journal “Nature” describes a research on the auroras on the planet Jupiter and on the differences with those on Earth. A team of researchers led by Barry Mauk of the Johns Hopkins University Applied Physics Laboratory investigated data collected in particular by two instruments aboard NASA’s Juno space probe finding traces of remarkable electrical potentials. They’re aligned with Jupiter’s magnetic field, which accelerates the electrons towards the atmosphere at energies even tenths times higher than those of the Earth’s auroras.
