Read on, and you'll learn how the sun's light reaches us, and how your night-light works.Did you know that moonlight is really sunlight? The moon can't make its own light, so it receives light from the sun and then sends it to us here on the Earth.

Readers will even learn how fast light can travel: from the moon to the Earth in less than three seconds! Veteran science author Franklyn M.
