1·The best possible explanation seemed to be that something physical-a ring of debris around rhea-was blocking the ions and electrons from reaching Cassini. (see Saturn Moon May Have rings-a First.)

最有可能的解释像是某些物质——围绕土卫五的碎片环——正阻碍离子和电子到达卡西尼。(参见《土星的卫星也许有光环——第一个》。)

2·Its particles are diffuse and may even extend beyond the bulk of the ring material all the way in to Saturn and all the way out to interplanetary space.

光环微粒是如此的弥散以致于它们从土星一直延伸到行星间空间。

3·This diagram illustrates the extent of the largest ring around Saturn, discovered by NASA's Spitzer Space Telescope.

本插图示意了由斯皮策空间望远镜发现的土星大光环的范围。

4·This impact would have sprayed huge quantities of material into space, forming a ring around Earth similar to, but much thicker than, those that now adorn Saturn.

这次碰撞已将大量的物质散发到了太空，从而形成了环绕地球的光环，类似于那些现在装饰土星的光环，但是要厚得多。

5·What was once the asteroid is now just a jagged ring of dust, encircling the Earth like one of the rings of Saturn.

在曾经是小行星现在只是一个锯齿状的尘埃环，包围像土星环一个地球。

6·The relatively small Numbers of particles in the ring wouldn't reflect much visible light, especially out at Saturn where sunlight is weak.

人数较少的粒子环，并不反映多少可见光，特别是已在土星在阳光薄弱。

7·If you could see the ring, it would span the width of two full moons' worth of sky, one on either side of Saturn.

如果你可以看到环，它将跨越宽度两满月'价值的天空，一个在任何一方的土星。
