The full light of our sun allowed the Cassini spacecraft to capture this image of Saturn's hexagonal polar jet stream, but the sun does not provide much warmth. In addition to being low in the sky (just like summer at Earth's poles), the sun is nearly ten times as distant from Saturn as from Earth. This results in the sunlight being only about 1 percent as intense as at our planet. Details: http://go.nasa.gov/2qTpxN9
