The shield is needed to keep the infrared telescope cold in space.

需要使用遮光罩让红外太空望远镜在太空中维持低温。

We knew that in order to find extremely distant galaxies, we would need an infrared telescope.

我们知道为了找到非常遥远的星系，就需要红外线望远镜。

Past observations of PAHs have been difficult in distant galaxies because of limitations in infrared telescope technology.

由于红外线望远镜技术的限制，过去很难观测到遥远星系中的多环芳香烃。

The Webb is a large infrared telescope designed to gather more in-depth data and explore parts of space never observed before.

韦布空间望远镜是一架大型红外望远镜，旨在收集更深入的数据，探索以前从未观测到的太空部分。

The James Webb Space Telescope, the successor to Hubble, is a gigantic infrared space telescope currently scheduled to launch in late 2018.

哈勃望远镜的继任者詹姆斯·韦伯太空望远镜是一个巨大的红外太空望远镜，目前计划于2018年底发射。

Infrared technology and infrared telescopes started to come online in earnest.

- 红外技术和红外望远镜开始正式上线。

That kind of light can pierce the dark disk, and when we use infrared telescopes we can see the protostars forming in the centers of those disks.

这种光可以穿透黑色的星盘，当我们使用红外望远镜时，我们可以看到原恒星在星盘中心形成。

NASA's Amber Straughn told VOX that Webb can't look at earth because it's an infrared telescope and the earth is warm and would just glow in that spectrum of light.

美国航空航天局的Amber Straughn告诉Vox，韦伯不能看向地球，因为它是一个红外线望远镜，而地球是温暖的，在红外线光谱中会发光。

That is important because this is an infrared telescope and we have to use infrared light to see those first stars and galaxies but everything above absolute zero glows in infrared.

这很重要，因为这是一个红外望远镜，我们必须使用红外线来看到第一批恒星和星系，但所有在绝对零度以上的东西都会发出红外线。

So that particular telescope is not quite as big or expensive as JWST, but it is also an infrared telescope that's designed to see the Universe in more of a broad swath.

因此，该特定望远镜不像 JWST 那样大或昂贵，但它也是一种红外望远镜， 旨在更广泛地观察宇宙。
