Supernova explosions are also predicted to be responsible for producing heavy elements such as gold, platinum and uranium.

据预测，超新星爆炸也会产生诸如金、铂和铀等重元素。

It is typically assumed that the collapse of massive stars into black holes is associated with a powerful supernova explosion.

通常假设大质量恒星坍缩成黑洞与强大的超新星爆炸有关。

If you want to go any farther than the element iron, you actually need a very violent explosion, a supernova explosion.

如果你想得到铁之后的元素，那就需要非常剧烈的爆炸，超新星爆炸。

This is a galaxy about 55 million light years away from Earth, but this is a supernova explosion in that galaxy.

这个星系离地球大约 5500 万光年，但是这里的超新星爆炸。

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年发生的超新星爆炸事件。

" The most likely source of neutrinos and cosmic rays in our galaxy, are the remains of past supernova explosions, " Taboada added.

“我们银河系中最有可能产生中微子和宇宙射线的是过去超新星爆炸的残留物，”塔博阿达补充道。

This is a supernova explosion, the explosive death of a massive star, and they're incredibly violent cosmic events, as this picture beautifully shows.

这就是超新星大爆炸，大恒星轰轰烈烈的死亡，它们绝对是狂野至极的宇宙大事件，正如这张绚丽的图片。

These supernova explosions signal the demise of very massive stars.

这些超新星爆炸标志着非常大质量恒星的消亡。

That's how insanely powerful supernova explosions are.

，这就是超新星。

When a star of this enormous size dies, after fusion in its core is no longer possible, the result is a brilliant supernova explosion.

当一颗如此巨大的恒星死亡时，在其核心不再可能发生核聚变后，结果就是一场辉煌的超新星爆炸。

This implies that somewhere in the universe, there's a supernova explosion every second or so.

这意味着在宇宙的某个地方，每隔一秒左右就会发生一次超新星爆炸。

But now you know that we also inhale the waste products of supernova explosions.

但现在你知道我们也吸入了超新星爆炸的废物。

It finds supernova explosions in remote galaxies and uses the light from the explosion as a yardstick to measure the distance from earth to the galaxy.

哈勃发现在遥远星系发生的超新星爆炸，再用爆炸发出的光做为量尺测量从地球到发生超新星爆炸的星系的距离。

So every bit of you, or at least the majority of it, came from one of these supernova explosions.

所以你们的每一点， 或者至少你们的大部分，都来自这些超新星爆炸中的一次。

And for a brilliant month, one supernova explosion can be brighter than an entire galaxy containing billions of stars.

对于一个明亮的月份，一颗超新星爆炸可能比包含数十亿颗恒星的整个星系还要亮。

Anything past iron has to be formed much more violently in a supernova explosion or in the case of very large atoms, two colliding neutron stars.

铁之后的元素都必须在更激烈的超新星爆炸中形成，或是在两个原子都非常大的情况下，由两颗中子星相撞形成。

The most famous of all of them is probably the supernova explosion that gave rise to the Crab Nebula.

其中最著名的可能是产生蟹状星云的超新星爆炸。
