Sweet Sixteen: Jupiter in Motion
This video, made up of 16 images assembled from Voyager 1 data by astro-artist Björn Jónsson and animated by Ian Regan, shows a time period spanning 16 Jupiter days (about 7 days Earth-time) wherein we can briefly observe the dynamics of the different cloud belts and spinning storms in the gas giant’s swirling atmosphere. Especially prominent is the Great Red Spot, a monstrous hurricane in Jupiter’s southern hemisphere three times the size of Earth and over 300 years old. Very cool!
The video is somewhat true-color, although a bit washed-out because Voyager 1’s CCD cameras were not calibrated to detect the color red as our eyes would see it…since Jupiter’s atmosphere has a lot of red in it, the closest approximation to that hue in the image data received is a less intense orange coloration. In other words, Jupiter would actually look a lot more vibrant to the human eye.

Voyager 1 was launched in September of 1977 and made its closest pass by Jupiter on March 5, 1979. Completing its Jovian encounter in April, Voyager 1 sent back almost 19,000 images of the giant planet and its moons before continuing on to pass by Saturn. It is now the most distant active spacecraft – and man-made object – still sending back data from the edge of the solar system nearly 11 billion miles away.
