Jupiter's Great Red Spot is a giant storm, larger than the Earth, which has formed Jupiter's most prominent feature for at least the last 400 years. The size, shape and colour of the feature vary with time: currently it is shrinking gradually. This image was taken by the Voyager 1 spacecraft in 1979. Credit: NASA
