In another portion of Chaco Canyon, a pictograph high on an overhang has been interpreted as marking a supernova explosion in 1054.

在查科峡谷另一处，悬崖高处的象形文字经翻译后被解读为记录1054发生的超新星爆炸事件。

For example, the data include information about more than 1,000 exploding stars, or supernovas.

例如，这些数据涵盖了1千多个爆发星体，或称为超星体的信息。

But what if we could anticipate a supernova before its light reached us?

或许，我们可以尝试在光线传达到地球前 预测超新星的发生？

So anything heavier than iron has to be created in a supernova explosion.

因此，所有比铁重的元素都是在超新星爆炸中产生的。

This is the star that's exploded. That's a supernova.

这是爆炸的恒星。那是超新星。

And they still had some iron-60 left over to account for-the stuff produced by supernovas.

们一些同位素铁-60来解释超新星产生的物质。

Actually, we know now it was the last recorded supernova in the Milky Way.

实际上，我们现在知道那是银河系中最后一次记录的超新星。

Maybe six out of a trillion stars explode into fiery balls of supernova death.

也许只有一兆分之六的恒星将会经历超新星爆炸。

But where did they come from? Could they have formed after their star went supernova?

但它们是从何而来呢？它们是在恒星发生超新星后形成的吗？

Rick, Supernova's getting away. Eh, who cares?

瑞克，超新星跑了。谁在乎？

Neutron stars are the extremely dense remnants of supermassive stars that have exploded as supernovae.

中子星是极其密集的超大质量星体爆炸后残留来的物体，这些星体曾经是超新星。

'Many are actually long dead...' - Tom, is that you? - '. .exploded into supernovas.'

很多已经停止了运转...-汤姆，是你吗？-...爆炸后变成超新星。

Well, as long as I'm a " Superstar" and not a supernova.

只要我是超级巨星，而不是超新星就好了。

Looks like nothing to you, but that's a supernova.

你或许觉得看起来没什么，但那是个超新星。

Saul's team spent six years perfecting a new system of supernovae on demand.

索尔的小组花了六的时间完善了一套新的系统来搜寻超新星。

One of my favorite nebulae in the sky is Barnard's Loop, a huge arc of material that's formed either by the expanding gas from supernovae or the winds of all the massive stars being born in the Orion complex.

天空中我最喜欢的一个星云是巴纳德环，一个由物质组成的巨大弧形，它要么是由超新星膨胀的气体形成的，要么是由猎户座复体中诞生的所有大质量恒星的风形成的。

There's a rare kind of supernova explosion that's like a standard interstellar headlight – it's about 5 billion times brighter than our sun, and, crucially, it's very consistent in its brightness.

有一种罕见的超新星爆炸，就像一个标准的星际前灯一样—它比我们的太阳亮50亿倍，而且关键是，它的亮度非常一致。

The expanding debris from this thousand year-old supernova is still moving into space at about 5 million kilometers per hour But the image is more than just a snapshot of ancient history.

那个有上千历史的“超新星”爆炸的残留物至今在以5百万公里/小时的速度向太空中飞散，不过哈勃的图像不光是远古历史的快照。

If at some moment, one star explodes like a supernova, the remaining one flies away at the speed with which it rotated.

如果在某个时刻，一颗恒星像超新星一样爆炸，的一颗会以它旋转的速度飞走。

These stars existed over 13 billion years ago but had short lifespans of only 3 million years before undergoing supernova explosions, giving rise to the second-generation stars observed by the researchers.

这些恒星存在于 130 亿前，但在经历超新星爆炸之前寿命只有 300 万，从而产生了研究人员观察到的第二代恒星。
