Similarly, our own present primitive chemical rockets, though good enough to orbit men, have no chance of transporting us to the nearest other star, four light years away, let alone distances of tens or hundreds of light years.

同样，我们目前使用原始化学火箭，虽然把人送入轨道，但尚不能把我们送到离我们最近、相距4年其他星球上去，更不用说几十年或几百年远地方了。

It's the thing that collects the light that's come from millions or billions of light years away and brings us that information that can allow us answer those questions.

What you're looking at is thousands of light years away, it's a planetary nebula, a giant cloud of gas that forms around an ancient star that hasn't yet exploded.
