Measurements by the Juno Spacecraft (NASA).
'Jupiter, the largest planet in the Solar System, is best known for its colourful storms. Now astronomers have focused on another beautiful feature of the planet, using the ultraviolet capabilities of the NASA/ESA Hubble Space Telescope. The extraordinary vivid glows shown in the new observations are known as auroras. They are created when high energy particles enter a planet’s atmosphere near its magnetic poles and collide with atoms of gas.'
