Story Synopsis
Have you ever wondered why the daytime sky looks blue? This story gives a gentle explanation. Miluna shares that sunlight is made of many colors. When that light enters Earth’s atmosphere, tiny air molecules bump the light and scatter it. Blue light scatters more easily than red, so blue spreads across the sky and reaches your eyes from all around. At sunrise and sunset, the light travels through more air, so the sky can look orange, pink, or red. The tone stays calm, clear, and wonder-filled—perfect for curious minds.

In One Glance
Sunlight contains many colors. In the atmosphere, tiny molecules scatter light, and shorter wavelengths—like blue—scatter more strongly. That makes blue light come to us from many directions, so the sky appears blue. When the Sun is low, the light passes through more atmosphere. More blue light gets scattered away, and the remaining light looks warmer, which is why sunsets can be orange or red. The story explains scattering gently without heavy math.
