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

气胶是世界上最轻固体材料之一。

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

也许是由一叫气溶胶材料构成。

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

尘号气胶收集器能收集粒。

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

气胶是一内部液体全部被气体替胶。

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

气胶是绝佳绝缘体，因为其内部气体不太能导热。

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

我们可以看到气胶里有许多撞击痕迹。有大也有小。

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

气胶非常适合隔热，因为里面空气不能很好地传递热量。

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胶，做窗户隔离......还是等它们便宜些吧。

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胶方式：首先，他们用硅或碳化合物之类东西制造胶。

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

另外，它们几乎是透明，这意味着我们可以使用气胶来隔离地球上窗户… … 当它们变得更便宜时。
