Maybe they'd be made out of a material known as aerogel.

也许是由一种叫气溶的材料构成。

The aerogel in the Stardust was able to collect particles from the comet.

尘号的气凝收集器能收集彗颗粒。

Aerogels are one of the lightest solid materials in the world.

气凝是世界上最轻的固体材料之一。

Aerogels are great for insulation, because the air inside doesn't transfer heat very well.

气凝是绝佳的绝缘体，因为其内部气体不太能导热。

Aerogels are gels where all the liquid has been replaced with gas.

气凝是一种内部液体全部被气体替代的凝。

We can see lots of impacts into the aerogel. There are big ones and there are small ones.

我看到气凝里有许多的撞击痕迹。有大的也有小的。

Plus, they're almost transparent, which means we could use aerogels to insulate windows here on Earth… when they get cheaper.

再加上它几乎透明，这也就意味着我在使用气凝，做窗户隔离......还是等它便宜些吧。

Aerogels are great for insulation, because the air inside doesn’t transfer heat very well.

气凝非常适合隔热，因为里面的空气不能很好地传递热量。

Without going into all the details, Kistler won his bet, and at the same time invented  the first aerogel.

在没有详细说明所有细节的情况下， 奇石乐赢得了他的赌注，同时发明了第一个气凝。

And of course, during this flyby, Stardust had  its aerogel collector exposed, and it was rapidly collecting dust samples.

当然，在这次飞越过程中， 尘号的气凝收集器暴露在外，它正在快速收集灰尘样本。

That’s basically how scientists create aerogels: First, they make a gel out of something like silicon or carbon compounds.

这基本上就是科学家制造气凝的方式：首先，他用硅或碳化合物之类的东西制造凝。

Plus, they’re almost transparent, which means we could use aerogels to insulate windows here on Earth… when they get cheaper.

另外，它几乎是透明的，这意味着我使用气凝来隔离地球上的窗户… … 当它变得更便宜时。

The trails left behind in the aerogel would  also be useful for scientists to spot where a particle had been captured.

气凝中留下的痕迹也有助于科学家发现粒子被捕获的位置。
