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年发生的爆炸事件。

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

例如，这些数据涵盖了1千多个爆发体，或称为体的信息。

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在爆炸中产生的。

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

这爆炸的恒。那。

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

们还剩下一些同位素铁-60来解释产生的物质。

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

实际上，我们现在知道那银河系中最后一次记录的。

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将会经历爆炸。

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

但它们从何而来呢？它们在恒发生后形成的吗？

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

瑞克，跑了。谁在乎？

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

中子极其密集的大质量体爆炸后残留下来的物体，这些体曾经。

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

很多已经停止了运转...-汤姆，你吗？-...爆炸后变成。

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

只要我级巨，而不就好了。

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

你或许觉得看起来没什么，但那个。

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

索尔的小组花了六年的时间完善了一套的系统来搜寻。

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云巴纳德环，一个由物质组成的巨大弧形，它要么由膨胀的气体形成的，要么由猎户座复合体中诞生的所有大质量恒的风形成的。

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.

有一种罕见的爆炸，就像一个标准的际前灯一样—它比我们的太阳亮50亿倍，而且关键，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.

那个有上千年历史的“”爆炸的残留物至今还在以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，一颗恒像一样爆炸，剩下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.

这些恒存在于 130 亿年前，但在经历爆炸之前寿命只有 300 万年，从而产生了研究人员观察到的第二代恒。
