Caption:

Roughly true color image of the Great Red Spot of Jupiter as taken by the Galileo imaging system on June 26, 1996. Because the Galileo imaging system's wavelength sensitivities go beyond those of the human eye, this is only an approximation of what a human observer would have seen in place of the Galileo spacecraft. To simulate red as our eyes see it, the near-infrared filter (756 nm) image was used. To simulate blue as our eyes see it, the violet filter (410 nm) image was used. Finally, to simulate green as our eyes see it, a combination of 2/3 violet and 1/3 near-infrared was used. The result is an image that is similar in color to that seen when looking through a telescope at Jupiter with your eye, but allowing detail about 100 times finer to be visible!
