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。

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

也许是由一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，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.

我们可以看到气凝胶里有许多的撞击痕迹。有大的也有小的。

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

气凝胶非常适合隔热，里面的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凝胶，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。

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

另外，它们几乎是透明的，这意味着我们可以使用气凝胶来隔离地上的窗户… … 当它们变得更便宜时。
