So gold, it turns out, is a great reflector of infrared light.

所以，事实证明，黄金是红外的极佳反射器。

These pits gather infrared information that is integrated with visual information in the optic tectum.

这些孔将融合了视觉的红外信息汇集到视被盖。

And there is plenty to be absorbed.

有大量的红外需要吸收。

It works by sending infra-red light into tissues and analysing what bounces back.

它先向身体组织发射红外，然后再分析反射回来的红外。

One potential sacrifice is WFIRST, an infra-red space telescope intended for launch in 2020.

其中最有可能被牺牲的项目是计划在2020推出的红外太红远镜。

It is equipped with the latest technology to observe infrared waves.

它配备了最新的红外观测技术。

NASA's WISE satellite is a space telescope that carefully surveyed the universe in infrared light.

NASA 的“广域红外探测器”（WISE）卫星是利用红外仔细宇宙的太空远镜。

Infrared has a longer wavelength than visible light.

红外的波长比可见光更长。

They just lit the scene with infrared lights from the " witness cameras, " they're called.

他们只是用“目击者摄像机”发出的红外来照亮现场。

Its dim thermal glow was just barely discernible to the infrared eyes of WISE and Spitzer.

WISE和Spizer的红外镜也只能依稀辨别褐矮星微弱的光芒。

It's actually infrared light, and the only difference between infrared and visible light is the wavelength.

实际上这是一种红外，对于可见光和红外来说唯一的区别就是波长。

Well, some astronomers. Researchers using the Spitzer Space Telescope could not see Fomalhaut b at all in infrared light.

不过，有些宇航员却不能。宇航员用斯皮策太空远镜拍摄的红外图里根本没有它的身影。

This enhanced super-vision allows the animals to not only see in infrared, but to discriminate between different infrared patterns.

这种增强的视觉不仅能让动物看到红外，还能区分不同的红外模式。

A similar infrared boost could someday allow us humans to break through our natural visual limitations.

某天，类似的红外增强技术可能会让我们类突破自然的视觉限制。

These can let through too much infrared and ultraviolet light, and again can dilate your pupils, actually making things worse.

过多的红外和紫外都能穿过他们，同样会使瞳孔扩散。实际上让情况更糟糕。

Infrared can pass through human tissue more easily than some other wavelengths of light, like the visible spectrum or UV.

相比其他光的长波长，红外更加容易的穿过体组织，比如可见光谱或UV。

This week, news of rebirth. NASA's WISE satellite is a space telescope that carefully surveyed the universe in infrared light.

本周，是关于重生的新闻。NASA的智慧号卫星是探寻宇宙的红外太空远镜。

It could also cut the project's cost (its present price tag is about $1.6 billion) and shorten its development time.

也可以降低该项目的花费（红外远镜的当前市价为16亿美元）并缩短研制时间。

It's just doing it in colours that we can't see in the infrared.

它只是在我们看不见的红外区域发出颜色。

But there's starting to be more of these other infrared colours.

但是开始出现更多这些其他的红外颜色。
