Why Is the Sky Blue? | NASA Space Place – NASA Science for Kids
Why Is the Sky Blue? The Short Answer: Sunlight reaches Earth's atmosphere and is scattered in all directions by all the gases and particles in the air. Blue light is scattered more than the other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.

The air molecules from Earth's atmosphere scatter out most of the blue light. The remaining light reflects onto the Moon's surface with a red glow, making the Moon appear red in the night sky. The name "blood moon" is also sometimes used for a Moon that appears reddish because of dust, smoke or haze in the sky.
