They shimmer with crushed rock and ice.

环由碎石冰晶组成，波光闪闪。

The two black bands around their neck give them their name.

他们的得名源脖子周围有两圈黑色环。

This alkaline ring complex, formed when continents broke apart, left behind a valley with remarkably fertile soil.

这个碱性环是大陆分裂时形成的，留下了一个土壤非常肥沃的山谷。

So there's this idea that if, you know, a civilization becomes, you know, advanced enough that it's really using geosynchronous orbit, that you actually get a belt, something that would actually be detectable from a distance via a transit.

所有一种想法是， 如果一个文明足够先进，能够利用地球同步轨道，那么实际上会形成一个环，这个环从远处通过凌日现象检测到。

It's a belt that's out at the very far end of our solar system, a belt they've named the Kuiper Belt, in honor of Gerard Kuiper, an astronomer who predicted that this belt might exist.

那是一个位我们太阳系最外端的环，他们将其命名为柯伊伯，文学家杰拉德·柯伊伯， 他曾预测这个环能存在。

The Kenlo Owen volcano is part of the hotbed of volcanic and seismic earthquake activity that encircles the Pacific Ocean, what's known as the Ring of Fire.

肯洛欧文火山是环绕太平洋的火山和地震活动热点地的一部分，也就是所谓的火环。

It looked at the planet's thin rings and discovered 11 new moons, all of which are now named after Shakespearean characters, as is the rule for Uranus.

它观察了这颗行星稀薄的环， 并发现了11颗新卫星，这些卫星现在都莎士比亚作品中的人物命名，这也是王星的命名规则。

More specifically, the chances that a randomly chosen vector lands in that band  should be that area divided by the total surface area of the sphere.

更具体地说，一个随机选择的向量落在那个环中的概率应该是那个环的面积除整个球体的表面积。

One recaptured bird had been banded almost 12 years earlier.

大约 12 年前，一只重新捕获的鸟已被贴上环。

However, Voyager 1 showed us that these rings are actually  made up of hundreds of thin ringlets.

然而，旅行者1号向我们揭示，这些环实际上是由数百个细小的环组成的。

What astronomers have realized is that there's another belt in our solar system.

文学家意识到，我们的太阳系中还有一个环。

And I always advise parents, or even people for themselves, you right here, wherever we are, biggest city on earth, Manhattan, where I was growing up as a 12-year-old outside of Manhattan.

我总是建议父母们， 或者个人自己，无论我们身处何地， 哪怕是在地球上最大的城市——曼哈顿，我12岁时就在曼哈顿外长大。 在这里，你同样看到月球上相同的环形山， 土星的环， 木星的卫星， 及金星的相位。

They appear scattered around the rings in this photo, and  are said to resemble broad spokes in a wheel.

在这张照片中，它们看似散布环各处，据说形似车轮上的宽辐条。

And then the area of the band should be that circumference  times its thickness, that little delta theta.

然后这个环的面积应该是周长乘它的厚度，也就是那个小的Δθ。

Gravity is pulling the rings into the planet, turning them into a kind of dusty rain of ice  particles.

引力正将这些环拉向行星，使它们化作一场冰粒尘埃般的细雨。

Voyager 2's observations unveiled more details about the known rings of Uranus, and  discovered two more.

旅行者2号的观测揭示了王星已知环的更多细节，并发现了另外两个环。
