The sky is blue because Earth has air, and the air scatters light from the sun. When we look up, all that scattered blue light makes the sky seem blue. But on the moon, there's no air, so there’s no scattering, only blackness. It's like looking at a night sky with no stars or lights around you.
Examples
- Imagine you're sitting under a blue blanket on Earth; that’s your sky. On the moon, it's like being in a dark room with only one light bulb shining at you.
