Unlike radio, light waves will not penetrate walls.

可见不同无线电波，无法穿透墙壁。

This is what we call “visible light, ” also known as the visible spectrum.

这就是们所说的“可见”，又叫可见谱。

Together, all the colors make up the spectrum of visible light—the light we can see.

所有的颜色一起构成了可见的谱——们所能看到的。

Light, both visible and invisible, is all around us.

可见和不可见都在们身边。

Just like visible light, x-rays are less likely to penetrate denser materials.

可见，X线难以穿过密度高的物体。

AVIRIS was also deployed to capture images of a massive natural gas blowout.

机载可见/红外成像谱仪还用捕获大规模天然气井喷的图像。

And finally, we arrive back thirteen billion years ago, at the beginning of visible light.

最后，们抵达 130 亿年前抵达可见的起源。

These waves mostly just pass through our bodies without interacting at all, but they are on the same spectrum as the visible light we see, just different in size.

这些多数穿透们身体的波并不影响们，和平日映入眼帘的可见属相同谱，只是大小不同。

This is the moon rising over Earth, and this is what we now call a selfie, which at that time, by the way, that word didn't exist. (Laughter) It's at Mars. It was taken by the CIVA camera.

这是月球在地球另一侧升起，这是们现在所称的自拍，顺便说一下，那个时候“自拍” 这个词还不存在。（笑声）这是在火星上， 由彗星红外与可见仪 相机拍摄的。

With the increasing diversification of modern detection means, for a single spectrum, such as visible light, infrared light, or for a single type of detector, such as radar, laser detection has long been unable to meet people's needs for " invisibility" .

随着现代探测手段的日益多样化，针对单一谱，如可见、红外，或针对单一型的探测器，如雷达、激探测早已不能满足人们对 “隐身”的需求。

Sunlight is composed of electromagnetic waves and is our primary source of ultraviolet radiation, which has a shorter wavelength than visible light and carries more energy.

太阳是由电磁波组成的，也是们接收到的紫外线的主要来源，它有相较可见更短的波长 也带有更多的能量。

There's an exciting European filter, it's called TriAsorb that covers into visible light, specifically blue light, we're learning more and more every day about how blue light ages the skin, affects melasma, rosacea, other dermatologic issues.

欧洲出现了一种令人兴奋的防晒剂，叫做TriAsorb，可以覆盖可见，特别是蓝。们每天都在越来越了解蓝是如何老化皮肤，发展出黄褐斑、酒渣鼻和其他皮肤病的。

Alive, some corals in shallow waters shimmer: They absorb ultraviolet radiation from the sun, which can prohibit growth in other organisms, and then emit it as visible light, in beautiful colors.

活着的一些浅水珊瑚会闪闪发：它们吸收来自太阳的紫外线辐射，这可能会抑制其他生物的生长，然后将其以可见的形式发出，呈现出美丽的颜色。

Even the particles we do see are thought to be just visible blips of energy fields that permeate the entire universe, like waves cresting above an invisible ocean.

甚至们真实看到的粒子也被认为只是渗透整个宇宙的能量场的可见点，就像波浪在看不见的海洋上翻腾。

But radio waves, which have wavelengths ranging from 100 microns to 100 kilometers, are much lower energy and can't excite your eyes, so they are invisible to us.

然而，无线电波波长介一百微米到一百公里之间，能量较低，无法激起感细胞作用，所以为不可见。

One day, we will build a meta material out of nanotechnology that will bend visible light so that anything inside that capsule will become invisible.

有朝一日们将建造一种来自纳米技术的超材料，它可以弯曲可见，使胶囊内的任何东西都变得不可见。

This is like the discovery of radio astronomy or this is like starting radio astronomy after only being able to observe the universe in visible light.

这就像对射电天文学的发现——或者说在只能用可见观测宇宙之后，们开启了射电天文学。

By looking at different parts of the visible and infrared spectrums, the two new telescopes will complement each other, says Magellan Telescope director Patrick McCarthy.

该望远镜的负责人帕特里克·麦卡锡表示通过观测可见及红外线的不同部，这两架新望远镜将进行优势互补。

Because researchers have developed an injectable, nanoscale antenna, which they've used to allow mice to see beyond their normal visual spectrum and into the infrared.

因为研究人员已经开发出了一种可注入的纳米级天线，他们已经用它让老鼠看到了超出正常可见谱的红外线。

Those elements tend to take on bright colors because the way their electrons are arranged lets them absorb visible light with certain wavelengths.

这些元素倾向表现明亮的颜色，因为它们电子的布使它们吸收固定波长的可见。
