Have you ever wondered why the sky looks blue? Sunlight seems white, but it is really a mix of many colors. When sunlight enters the air, it hits tiny gas particles. These particles scatter blue light much more than red light, because blue light travels in shorter waves. As a result, blue light spreads across the whole sky, and that is the color we see during the day. At sunset, the light passes through more air before it reaches our eyes. Most of the blue is scattered away, so we mostly see red and orange. This simple idea explains a beautiful part of nature that people notice every single day.
