Approaching Jupiter.

In 1979 the Voyager 1 spacecraft compiled this view as it approached the gas giant Jupiter . Snapping a picture every time the Great Red Spot was properly aligned, the above time-lapse sequence shows not only spot rotation but also the swirling of neighboring clouds . Since Jupiter takes about 10 hours to rotate, this short sequence actually covers several days. Voyager 1 shot past Jupiter rapidly taking pictures on which many discoveries would be made, including previously unknown cloud patterns , rings , moons , and active volcanoes on Jupiter's moon Io . Voyager is moving so fast that it will one day leave our Solar System .
