We knew nothing about the structure in Saturn's rings.

我们对土星的结构一无所知。

What are Saturn's rings believed to be made of?

土星被认为由什么构成的？

I have just imagined flying along in a shuttlecraft across the ring right close to the rings.

我象着乘坐航天飞机飞过土星，就在离土星很近的地方。

And just like the rings of Saturn, Earth's rings wouldn't last forever.

并且就像土星一样地球的行星不会永存。

So yeah, Saturn's rings are flat.

所以土星确实非常扁平。

Their mass was the missing piece of the puzzle to determine their age.

“土星的质量确定其年龄的缺失线索。”

They may look for water on Mars or take close-up pictures of Saturn's rings.

这些卫星或在火星上寻找水，或拍摄土星的特写照片。

The bump is the result of the particles that make up the ring becoming distorted by the presence of something large.

新的大物体的出现使土星扭曲，这个凸起就构成土星的颗粒组成。

The substances are the same material that creates one of Saturn's rings, called the " E" ring.

这些物质与形成土星之一“E”的物质相同。

What really gets me about Saturn's rings is their scale.

土星真正让我惊讶的地方的它的尺寸。

And when they crunched the numbers, the data suggested an age of no more than 100 million years.

当他们运算这些数字时，数据显示土星的年龄不超过1亿年。

I still remember seeing Saturn in the eyepiece, a perfect jewel, the rings small but vivid and sharp.

我仍然记在目镜中看到的土星，一件完美的珠宝，土星虽小却生动清晰。

As it plowed through the material around the proto-Saturn, the moon's icy layer got stripped off, forming the rings.

当它穿过原始土星周围的物质时，卫星的冰层被剥离，形成了土星。

The data suggests that Saturn's rings are young by celestial body standards, that is possibly a few hundred million years old.

这些数据表明，按照天体的标准，土星还很年轻，可能有几亿年的历史。

Saturn as a planet is of course an amazing place, but come on. When you think Saturn, you think rings.

作为一颗行星，土星当然一个神奇的地方，不过，当你起土星时，多半就会到土星。

A ring of debris formed around the Earth, sort of like Saturn's rings, unlike Saturn's rings that all collected into our moon.

围绕地球形成的碎片，有点像土星，不像土星都聚集在我们的卫星上。

The pieces of ice and rock that form rings around Saturn are not considered moons themselves, NASA said.

NASA说，围绕土星形成的冰块和岩石本身并不被认为卫星。

In this way, the main belt is like Saturn's rings, whose gaps are carved out by the gravity of the orbiting moons.

这样，主小行星带就像土星一样，的空隙由轨道卫星的重力雕刻出来的。

Cassini's study of the system of Saturn's rings and moons brought many surprises.

卡西尼号对土星和卫星系统的研究带来了许多惊喜。

But it's as Cassini captures images with the sun directly above the equator, that the most surprising feature of the rings emerges.

但，当卡西尼号拍摄到太阳直射赤道上方的图像时，土星最令惊讶的特征出现了。
