Scientists from the Paris Observatory used the NASA/ESA Hubble Space Telescope to take a look at the auroras on Uranus – caused by streams of charged particles like electrons that come from various origins such as solar winds, the planetary ionosphere, and moon volcanism.
They become caught in powerful magnetic fields and are channeled into the upper atmosphere, where their interactions with gas particles, such as oxygen or nitrogen, set off spectacular bursts of light.
