Although northern lights also exist on giant planets such as Jupiter and Saturn, the newly discovered aurorae are thousands of times more powerful; furthermore, the same electrons that trigger these aurorae may drive weather
patterns on brown dwarfs, some of which have clouds.
«The atmospheric winds of
brown dwarfs seem to be more like Jupiter's familiar regular
pattern of belts and zones than the chaotic atmospheric boiling seen
on the Sun and many other stars,» said study co-author Mark Marley at NASA's Ames Research Center in California's Silicon Valley.
