The Moon looks so big and bright in the dark night sky, making it the most eye-catching treasure up there. But Little Panda wants to tell you a surprising little secret: the Moon itself doesn't emit any light at all! The gentle moonlight we see is actually Grandpa Sun shining his powerful light onto the Moon's bare surface, which then bounces (reflects) that light right into our eyes. It acts just like a giant 'mirror' hanging in the sky. Without the Sun, the Moon would just be a dark boulder. By the same token, when astronauts look at Earth from the Moon, Earth shines brightly too, because our Earth is also an expert at borrowing and reflecting sunlight!
