A Shadow on the Rings of Saturn
This picture of Saturn, taken by the Cassini spacecraft, shows the planet's night side and the shadow cast across its rings. From Earth, only the day side of Saturn is visible because Earth is closer to the Sun. The dark western limb of Saturn looms large, with complex concentric rings visible in the sunlight.
We cannot put this date's photograph on paper at poster size. We can print the nearest public archive plate to your date instead.
