你知道土星嗎？土星有一些特別的環，但是你知道嗎？在很久之前，當地球經過那些環的時候，看到的土星就像只有一顆星星，沒有環出現！這是因為土星的環真的非常薄，比一片刀片還要薄。從2004年到2017年，有一艘探測器叫做Cassini，它飛到了土星的附近，拍下了很多照片。最近，一位來自西班牙的朋友Fernando Garcia Navarro發現了2005年拍的照片。照片裡，土星的薄環看起來像藍色的絲帶，而土星上面的雲雲團團則像金色的夢。還有兩顆小月亮，Dione和Enceladus，就像環上的小圓丘，非常好看！
原文:
If this is Saturn, where are the rings? When Saturn’s “appendages” disappeared in 1612, Galileo did not understand why. Later that century, it became understood that Saturn’s unusual protrusions were rings and that when the Earth crosses the ring plane, the edge-on rings will appear to disappear. This is because Saturn’s rings are confined to a plane many times thinner, in proportion, than a razor blade. In modern times, the robotic Cassini spacecraft that orbited Saturn frequently crossed Saturn’s ring plane during its mission to Saturn, from 2004 to 2017. A series of plane crossing images from 2005 February was dug out of the vast online Cassini raw image archive by interested Spanish amateur Fernando Garcia Navarro. Pictured here, digitally cropped and set in representative colors, is the striking result. Saturn’s thin ring plane appears in blue, bands and clouds in Saturn’s upper atmosphere appear in gold. Details of Saturn’s rings can be seen in high dark shadows. The moons Dione and Enceladus appear as bumps in the rings.
