The Color of the Sky

Ever wonder why the sky is blue during the day but red at sunset?

You can thank a process called “Rayleigh scattering” and the idea is pretty simple:

When light passes through the atmosphere, it hits particles in the air and gets scattered in all directions

Not all light however scatters at the same time: blue light, having a shorter wavelength than red, reacts to only a short amount of atmosphere. This is why when the Sun’s overhead and the light passes through the least amount of atmosphere, the sky is a deep blue.

When the Sun’s setting or rising, the amount of atmosphere light waves must pass through are long, long enough to fish out and scatter red waves into the atmosphere, painting the world red.
