What makes the sky blue?

    Here’s a great explanation from NASA. I couldn’t have said it better myself!

    “Sunlight reaches Earth’s atmosphere and is scattered in all directions by all the gases and particles in the air. Blue light is scattered in all directions by the tiny molecules of air in Earth’s atmosphere. Blue is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.”

    There’s also a great explanation of different wavelengths of light on the website. So, in short, the sky looks blue because the blue wavelength of light is most readily scattered by the molecules in the atmosphere and makes its way to our eyes.
