Text, Jupiter's X-ray aurora mystery solved. July 26, 2021. Using data from multiple missions, scientists have uncovered the source of Jupiter's unusual X-ray auroras.

 
(DESCRIPTION)
NASA's Juno spacecraft observed the chain of events. Jupiter's outer magnetic field is struck by charged particles from the Sun. Electrically charged atoms "surf" the magnetic field lines over millions of miles, emitting a traceable pulse.
 
Animation of pulse. Orange lines cross over a bright orange light.
 
Text, Minutes later, the European Space Agency's XMM-Newton mission picks up a burst of X-rays as the atoms slam into Jupiter's atmosphere, creating the auroras. Over the course of a day, XXM-Newton saw the auroras pulse every 27 minutes, matching up with the observations by Juno.
