This releases energy, and creates heavier elements.

这会释放出能量，并产生更重的元素。

There's some helium and traces of heavier elements.

太阳中含有氦和少量较重的元素。

There are practically no heavy elements and metals.

几乎没有重金属元素。

This leads to the creation of heavier elements up to iron.

这导致了较重元素的产生，一直到铁。

Today you learned that massive stars fuse heavier elements in their cores than lower mass stars.

今天你学到了高质量恒星比低质量恒星在核心中融合更重的元素。

Heavy elements, like uranium, can only be created in a catastrophic cosmic explosion.

象铀一样的重元素只能在灾难性的宇宙爆炸中产生。

The heavy elements spread out and mixed with the outer layers of Jupiter.

重元素向外扩散并与木星的外层混合。

Observations of the targeted galaxy suggested it contained gas filled with heavy elements.

对目标星系的观测表明，它含有充满重元素的气体。

But across the universe, there are vanishingly small amounts of those heavy elements.

茫茫宇宙之中这些重元素的含量简直少到不能再少。

That technique for creating a new heavy element is inspired. Oh, well, thank you.

你的理论对合成新超重元素有着重大的意义。哦，谢谢。

The star shoots most of its innards into space, seeding the galaxy with heavy elements.

这颗恒星把它大部分的“内脏”射入太空，在星系中植入重元素。

Iron refuses to fuse any further, so the star is now jam-packed with heavy elements.

铁原子不会进一步聚变，所以这颗恒星现在充满了重金属元素。

The heavier elements that endured solar winds were all taken up by Mercury to form itself through the process of accretion.

经受太阳风的较重的元素都被水星吸收，通过吸积过程形成自己。

Massive stars explode and scatter their heavy elements into the Universe, and that takes time.

Only they can reach the extreme temperatures needed to create large amounts of the heavy elements.

只有这种恒星才能达到制造重元素所需的温度，大量生成重元素。

I mentioned that uranium is the heaviest element in the periodic table, but which is the lightest?

我提到过铀是元素周期表中最重的元素，但哪个元素是最轻的呢？

But still, there isn't anything objectively different about Gold, it's just like all the other, heavier elements like Platinum, Uranium and copper.

但是，黄金在客观上并没有什么不同，就像所有其他比较重的元素（如铂金，铀和铜）一样。

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。

Hydrogen fusion makes helium, helium fusion makes carbon, and each heavier element, in general, takes higher temperatures and pressures to fuse.

氢聚变产生氦，氦聚变产生碳，一般来说，每一种较重的元素需要更高的温度和压力才能进行聚变。

These conditions last for just 15 seconds, but it's enough to form the heaviest elements like gold.

这种情况只能持续大约 15 秒，但是已经足够产生一些重质基本元素了，比如说金元素。
