Told like a bedtime story.
For a curious 10-year-old. No jargon. Just a picture in your head.
When you stay too long in the sun without sunscreen, your skin turns red and stings the next day — a sunburn. The Sun is sending you a kind of light you cannot see, just past the violet end of the rainbow, with enough energy to actually damage your skin cells. This invisible burn-light is called ultraviolet, or UV. It's the same light a tanning bed glows with, and the same light that makes white shirts go ghostly under a blacklight at a party. Sunscreen is technically a tiny shield army. Wear sunscreen.
§ Strange but true
- 01Bees, butterflies, and birds see in ultraviolet. Flowers have secret runway markings just for them.
- 02The Sun emits enough UV to damage DNA. Our atmosphere blocks most of it. Without ozone, the surface would be sterile.
- 03Hot young stars glow in ultraviolet. The most violent corners of the universe are invisible to your eyes.
