| 1. | In 1988 we will be able to see saturn's rings in their fullest glory . 到1988年,我们将会看到土星环最壮丽的景象。 |
| 2. | This view looks upward from just beneath the ringplane 这景象是从土星环平面稍微下一点往上看到的。 |
| 3. | Saturn ' s ring system 土星环系 |
| 4. | Crater - scarred rhea floats in the distance , peeking out from behind saturn ' s partly shadowed rings 有许多坑和斑纹的土卫五漂浮在远方,正从土星环外面的阴暗部分窥视着。 |
| 5. | Titan ( 5 , 150 kilometers across ) is surrounded by a thick photochemical haze which scatters the sun ' s light 土星环由于不是连续,有很多裂缝,因此泰坦在环后也能从环中看见。 |
| 6. | Saturn ' s rings are a graceful local example , but not the only one ; all the giant planets in our solar system have rings 优雅的土星环是区域性?例,但并不是唯一;太阳系的所有巨行星都有环。 |
| 7. | After becoming the first spacecraft to enter saturn ' s orbit , cassini sent back this image of a portion of the planet ' s rings 在人类的一艘环土星探测器? ?卡西尼号进入环土星轨道后,它向地球发回了土星环(部分)的图片。 |

| 10. | That means scientists have underestimated the mass of saturn ' s rings . they may be two to three times denser than previous estimates , the researchers said 这项结果代表科学家们低估了土星环的质量。土星环质量可能是原先推估的两到三倍,研究人员说。 |
