Recently, we observed two neutron stars colliding.

最近，我们观测到两颗中子星相撞。

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。

Well, we don't really know, but scientists think that it's likely colliding neutron stars could, in fact, be where most of the heavy metal end of the periodic table is born.

好吧，我们真的不知道，但科学家们认为很可能碰撞中子星实际上可能是元素周期表中大部分重金属的诞生地。
