A Giant mysterious mirror!!

You all might have seen a Crescent moon, The illuminated part of the moon looks bright but we can also see the darker part of the moon, If you observe carefully, you can see the other part of the moon, but not as bright as the illuminated part (Cresent part of moon), even though sun has no part in illuminating it.

Let me tell you, how we all can see that darker part of the moon on crescent moon day, it is caused by the sun's bright light reflecting off the earth's surface into the face of the moon. We even have a word for it, earthshine! So every time you see a crescent moon and a hint of a darker side of the moon, you are literally looking at the reflection of our earth, isn't it exciting to know? Next time, when you look at the sky remember you are acting as a gaint mirror !!
