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

气是世界上最轻的固体一。

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

也许是由一叫气溶的构成。

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

星尘号的气收集器能收集彗星颗粒。

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

气是一内部液体全部被气体替代的。

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

气是绝佳的绝缘体，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.

气非常适合隔热，因为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，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的方式：首先，他们用硅或碳化合物类的东西制造。

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来隔离地球上的窗户… … 当它们变得更便宜时。
