And they designed and built the instruments to endure the flights to Uranus and Neptune just on the off chance that the mission would be approved for that long and that's what happened.

他们设计并制造了仪器来确保“旅行者”号能完飞往天和海的飞行任务，同时希冀它能获批飞的更远，这也确实发生了。

“It is Uranus, my dear, ” said Professor Trelawney, peering down at the chart.

“是天，亲爱的。”特里劳妮教授低头看着图表，说道。

And Uranus will keep doing the side shuffle like nobody's watching.

天会继续它的旁曳步。

Uranus can be glimpsed with binoculars or a telescope under good conditions.

天可以在良好的条件下用双筒望远镜或望远镜瞥见。

Speaking of “ice, ” here's a really weird thing: Studies have shown that the pressure inside Uranus can break up methane molecules, squeezing the carbon in them so tightly that it actually forms diamonds!

说到“冰”，有一件很奇怪的事情：研究表明，天内部的力可以分解甲烷分子，将其中的碳缩得非常之紧，以至于实际上它都形了钻石！

But that's not all, the study also used images of Uranus gathered over the years to figure out why the planet appears to change colors with the seasons.

但这还不是全部，这项研究还利用多来收集的天图像来弄清楚为什么这颗行会随着季节而改变颜色。

As early as 1821, astronomers noticed that Uranus's orbit was behaving in a way that could best be explained by the gravity of another planet tugging on it.

早在1821，天文学家就注意到天的运行轨道，很有可能受到了另一颗行引力的影响。

But it's the orientation of the orbits of these moons and the rings themselves that singles out Uranus as the strangest of worlds.

但正是这些卫和环本身的轨道方向，使天为最奇特的世界。

The researchers' findings added a whopping 28 seconds to Uranus's previously estimated rotational period. And hey, every second on Uranus is precious.

研究人员的发现将之前估算的天自转周期增加了整整28秒。天上的每一秒都弥足珍贵。

Much of the knowledge about Uranus was collected when NASA's robotic spacecraft Voyager 2 flew past it in 1986.

关于天的许多知识都源于1986NASA的旅行者2号机器人航天器经过它时收集的信息。

You might know Babbage as the father of computing and Herschel as the guy who found Uranus.

你可能知道巴贝奇是计算机之父，而赫歇尔是天的发现者。

Neptune is more massive than Uranus; 17 times Earth's mass, versus just 14.5 for Uranus.

海比天更大；是地球质量的17倍，而天只有地球质量的14.5倍。

Unlike Neptune, Uranus does not generate much internal heat.

不同于海，天没有产生太多的内热。

For a better estimate, scientists used more than a decade's worth of Hubble data to track the movement of Uranus's auroras, which helped them zero in on the actual location of the planet's magnetic poles.

为了更精确地估算， 科学家们利用了超过十的哈勃数据来追踪天极光的移动，这帮助他们准确定位了该行磁极的实际位置。

If a roughly earth-sized object smashed into Uranus late in its formation history, then that would have had the proper amount of momentum to basically knock it on its side.

如果在天形历史的后期，有一个大致地球大小的物体撞上了天，那么这将会产生适当的动量，足以能把天撞倾斜。

" A future mission to Uranus is crucial to understanding not only the planet and magnetosphere, but also its atmosphere, rings and moons, " Jasinski said.

“未来前往天的任务不仅对了解这颗行和磁层，而且对了解它的大气层、光环和卫都是至关重要的。”

Just how different is Uranus dance?

天的舞蹈到底有多不同？

Uranus looks bizarre, the rings, rather than looking like that when you look for a telescope, they're actually orbiting up and over the top of the planet.

天看起来很奇怪，环并不是你在望远镜里看到的那样，它们实际上是在天的顶部绕轨道运行。

While Uranus has a hazy, mostly unremarkable atmosphere, Neptune has active and easily visible weather patterns, which gives it a more distinctive appearance.

天的大气朦胧，大部分无法看清，而海气象则十分活跃且清晰可见，所以看起来非常特别。

Uranus's weird tilt is just one of those many mysteries that astronomers are trying to solve with limited data.

天的怪异倾斜只是天文学家试图用有限的数据解决的众多谜团之一。
