Voyager I took this photo of Jupiter and its Great Red Spot from 20 million miles away in 1979. The first information on the physical, atmospheric and geological processes occurring on the planet was thus revealed. The first close-up image of the planet‘s atmosphere was taken, the temperature of the clouds was measured, the movement of winds in the bands and zones observed, lightning was detected in the dark hemisphere, and the velocity of the matter that constitutes the Great Red Spot was measured, revealing its anticyclonic nature.
