NASA’s Juno space probe captured footage of a green lightning bolt inside one of Jupiter’s vortices near the planet’s north pole during a flyby in December 2018. The footage was captured by the ultraviolet spectrograph on Juno and shows that the lightning bolt was a bright green color. Scientists theorize that the green hue may be due to the presence of sulfur and ammonia in Jupiter’s atmosphere. This rare occurrence is the first time that a lightning bolt has been observed at the gas giant’s north pole.
