Jupiter's UV aurora are generated by charged particles from its volcanic moon Io, NASA reveals
A spectacular and dramatic ultraviolet auroras on Jupiter is generated by charged particles escaping its volcanic moon Io, according to a new NASA study. The origins of the bright blue circular aurora were revealed by the NASA Juno spacecraft, which is currently studying the gas giant from orbit. The Jovian polar light show, also known as the auroral dawn storms, brighten up the early morning north and south poles of the massive world. These immense, transient displays of light evolve in a similar way to 'aurora substorms' that undulate across Earth's polar skies, according to NASA and the...
