But we get visible light.

and then the visible light will create an image of what the infrared light sees even though the visible light has never been near the physical object itself.

- Think about a photon of visible light emitted 380,000 years after the Big Bang, it travels through the universe unimpeded to arrive at our telescopes,

And that is where we get the visible light.

So an important question was how do you maximize the visible light given off by a hot filament?

process that that the sun emits all the colors of visible light in addition to some of these other colors that are not

to drive your cat insane, but whereas a laser emits visible light, a maser emits microwave radiation.

And as many of you may know, the part that we call visible light is actually less than a ten billionth

It is farther from Earth than Hubble, and it is optimized not for visible light observations like our eyes can see, but for infrared observations,

In Smith's case, he needed to emit radio waves, and they sit on the electromagnetic spectrum, alongside microwaves, infrared, and visible light.

And he'd say, I used to be scared of the dark, and then I realized that dark is just the absence of photons in the visible light wavelengths,
