What is the origin of 'sleep tight'? One of the mysteries of the English language finally explained.
The moon doesn't glow in a very real sense. It reflects the Sun's light. (Or the Earth's light if you're not on Earth and in the right position.) As Quora User says, the moon has a high albedo. So it reflects pretty well.
The Moon doesn't produce its own light. What you generally see when you look at the Moon is the brightness of the surface of the Moon lit by the Sun in the Moon's daytime. Next time you see the Moon in its very thin crescent phase, look carefully and you will see the whole Moon but the part that's not the bright crescent is very dim, but not black.
