Insects see green, blue and ultraviolet, and they see various shades of ultraviolet.

Then there's ultraviolet light.

Ultraviolet rays can cause skin cancer.

Similarly, the Extreme Ultraviolet Explorer (EUVE), launched in June 1992, produced the first all sky map in four extreme ultraviolet wavelength bands.

The impact, observed in regions of the electromagnetic spectrum ranging from the ultraviolet to long radio wavelengths, produced fireballs that left major visible marks on the planet it revealed a clearcut need for an inventory of comets and asteroids that may someday collide with Earth.

So we used ultraviolet A, which doesn't make vitamin D.

And then I put some ultraviolet filters on my camera and took a very, very long exposure with the particular frequencies of ultraviolet light and this is what I got.

Its oceans evaporated and its water vapor was burned away by ultraviolet light.

So this seems to be a feature of ultraviolet rays hitting the skin.

Let's first look at the relationship of ultraviolet radiation to the Earth's surface.

For over fifty years, ultraviolet radiation from the sun has been the number one suspected cause of skin cancer. Epidemiologic data from Australia, animal studies with artificial sources of ultraviolet light, and the development of skin cancer in individuals with a genetic inability to correct the DNA damage caused by ultraviolet radiation provided circumstantial evidence of the connection.

You can see the spectrum of the Earth, this Earthshine spectrum, and that is a very clear signal.

I compared the radio waves spectrum the size of it with the size of the visible light spectrum.

Vaccines that are broad spectrum.

But they vary even more, possibly moving towards infrared and ultraviolet in the extremes.

But if you look at the spectrum, birds and us, we see red, green and blue and see that spectrum.

It's a full spectrum of tools.

Here's another little flower different range of ultraviolet frequencies, different filters to match the pollinators.

In the winter, when you are skiing in the Alps, you may experience ultraviolet radiation.

And that could be the basis of a sunscreen because sunscreens work by absorbing ultraviolet light.

Conditions were significantly colder, but they were also less intense with respect to the ultraviolet regime.

So if we're somewhere in the Northern Hemisphere, look at what's happening to the ultraviolet radiation.

They're locations in the spectrum of sound.

Could make some sort of landmark points along a spectrum of improbability, which might look like the electromagnetic spectrum we just looked at.

HST has the unique capability of imaging and measuring the spectra of distant supernovae in ultraviolet light.

The TOMS 7 satellite data, shown here, show the annual average ultraviolet radiation at the Earth's surface.

The incrementally cooler colors blues, greens, yellows, and finally grays indicate areas of much lower ultraviolet radiation.

And we are simply running out of spectrum.

And light is part of the electromagnetic spectrum.

So here, further data that ultraviolet that's sunlight has benefits on the blood flow and the cardiovascular system.

And so what we did was we took a bunch of volunteers and we exposed them to ultraviolet light.

How much depends on where you fall in the spectrum.

Or take Korea, at the other end of the spectrum.

It doesn't emit in the electromagnetic spectrum. It doesn't reflect.

It's amazing that we can detect vegetation from a spectrum.

I think it will come from a spectrum like this.
