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

也许是由一种叫气溶胶的材料构成。

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

星尘号的气凝胶收集器能收集彗星颗粒。

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

气凝胶是一种内部液体全部被气体替代的凝胶。

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

气凝胶是绝佳的绝缘体，因为其内部气体不太能导热。

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

气凝胶是世界上最轻的固体材料之一。

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

我们可以看到气凝胶里有许多的撞击痕迹。有大的也有小的。

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

首先，科学家从诸如硅或碳化合物中制造明胶。

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

再加上它们几乎透明，这也就意味着我们可以在使用气凝胶，做窗户隔离......还是等它们便宜些吧。

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

气凝胶非常适合隔热，因为里面的空气不能很好地传递热量。

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们制造气凝胶的方式：首先，他们用硅或碳化合物之类的东西制造凝胶。
