The researchers also found a large amount of hydrogen cyanide at levels similar to comets from our solar system.

研究人员还发现这颗彗星含有许多的氰化氢，含量和太阳系彗星相似。

But there are also complex carbon compounds in here. So there's methanol, there's hydrogen cyanide, there's formaldehyde, there's dimethyl ether.

还有一些复杂的碳基化合物，比如甲醇 、氰化氢、 甲醛、 二甲醚。

It is 250,000 times more toxic than hydrogen cyanide, and was used to assassinate Russian dissident Alexander Litvinenko back in 2006.

它的毒性是氰化氢的 25 万倍，曾在 2006 年用于暗杀俄罗斯异见者亚历山大·利特维年科。

It's 2.5 million times more toxic than hydrogen cyanide, but only very tiny fractions of that lethal dose are used in commercial Botox.

它的毒性是氰化氢的 250 万倍，但只有极少含量的肉毒杆菌毒素用在商业中的保妥适中。

Also in the mix: formaldehyde and methanol, found in embalming fluid, mixed with faint traces of poisonous hydrogen cyanide, which has an almond-like aroma.

罗斯塔还在防腐剂中发现与微量含杏仁气味的有毒氰化氢混合在一起的甲醛和甲醇。

So the very good news is that these discs do indeed have hydrogen cyanide in them.

所以好消息是这些圆盘中确实含有氰化氢。

You see the hydrogen cyanide emission being spread out across the disc.

你可以看到氰化氢的排放分布在圆盘上。

And that means that we don't know where in the disc the hydrogen cyanide is coming from.

这意味着我们不知道圆盘中氰化氢的来源。

And older telescopes can detect only strong, simple signals of the sort emitted by small molecules like carbon monoxide and hydrogen cyanide, which have two and three atoms respectively.

并且老望远镜只能探测到一氧化碳（双原子）、氢氰化物（三原子）等小分子释放出的强的，简单的信号。

Is the hydrogen cyanide at the right place?

氰化氢放对地方了吗？

And what does a map of hydrogen cyanide look like in a disc?

圆盘中的氰化氢图是什么样子的？

Fumigants such as hydrogen cyanide, sulphur dioxide and DDT itself are now regarded in most places as too toxic to use.

氰化氢、二氧化硫和滴滴涕等熏蒸剂本身现在在大多数地方都被认为毒性太大而无法使用。

And that is exactly the problem we were facing with our single-pixel images of these discs with hydrogen cyanide.

而这正是我们在处理这些含有氰化氢的圆盘的单像素图​​像时所面临的问题。

So about a decade ago, I started a program to look for this hydrogen cyanide and other molecules in these planet-forming discs.

所以大约十年前，我启动了一个程序来寻找这些行星形成盘中的氰化氢和其他分子。

This is not places where we could research if there is any hydrogen cyanide around where these planets are forming.

这不是我们可以研究这些行星正在形成的地方周围是否有任何氰化氢的地方。

How many temperate planets are there out there that have water and hydrogen cyanide?

有多少温带行星有水和氰化氢？

But in most cases, we just don't detect hydrogen cyanide, but we detect it in the right place.

但在大多数情况下， 我们只是没有检测到氰化氢，而是在正确的地方检测到了。

So now we have our three ingredients that we need, you know, the temperate planet, water and hydrogen cyanide.

所以现在我们有了我们需要的三种成分，你知道的，温带行星，水和氰化氢。

You can see they all show the same thing -- lots of bright hydrogen cyanide emission coming from close to the center of the star.

你可以看到它们都显示出相同的东西——大量明亮的氰化氢辐射来自靠近恒星中心的地方。

But the organic molecule that seems to be at the center of the chemical networks that can produce biomolecules is hydrogen cyanide.

但似乎处于可以产生生物分子的化学网络中心的有机分子是氰化氢。
