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.

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.

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

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.

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.

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

You feel deep, deep guilt.

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

In those early days of our evolution, looking at the equator, we were bombarded by high levels of ultraviolet radiation.

Though likely once habitable, Venus was over the course of several billion years exposed to too much heat and ultraviolet light.

And the good thing about perceiving ultraviolet is that you can hear if it's a good day or a bad day to sunbathe, because ultraviolet is a dangerous color, a color that can actually kill us, so I think we should all have this wish to perceive things that we cannot perceive.

The kind of relationships when deep speaks to deep.

However, stratospheric ozone destruction in the polar regions and the consequent rise in dangerous ultraviolet radiation is still occurring at near record levels.

Deep.

The Solar Terrestrial Science Programme addresses the effects of solar ultraviolet and plasma emissions on the atmosphere and the magnetic field of the Earth.

Deep Decarbonization

Deep green.

Deep green.

Ozone, a molecule made up of three atoms of oxygen, forms a thin layer of the atmosphere that absorbs harmful ultraviolet radiation from the Sun.

Simultaneous measurements were made of electric and magnetic fields, particle distributions, plasma composition and waves, as well as imaging in the ultraviolet of the aurora variations.

We need to see deep trenches, the undersea mountains, and understand life in the deep sea.

Now, what we were careful to do was, vitamin D is made by ultraviolet B rays and we wanted to separate our story from the vitamin D story.

Because the problem there is just as severe, but it is more sinister, because vitamin D deficiency, from a lack of ultraviolet B radiation, is a major problem.
