Why does the moon glow?

The amount of reflected light.
All objects in space have a characteristic called albedo. That is why we can know how well or badly certain objects reflect light. For example, glass has a high albedo, while ground, on the contrary, has a low albedo.
The albedo of the moon is very low, because there are many curvatures on its surface, and the ground has a dark gray color. In this regard, it can only reflect 12% of the sun's rays. However, even this is enough to illuminate our Earth with a rather bright light.
During the full moon, the moon is so bright that it can be seen even in the daytime. It is curious that astronomers on such days have to stop their research, because the moonlight does not allow them to work normally.
Sometimes we can see a supermoon when the glow of the moon becomes 20% brighter than usual. A similar phenomenon occurs at the moments of maximum convergence of our planet with its natural satellite.
During a normal full moon, the illumination reaches no more than 0.1 lux. However, during a supermoon, these figures can triple.
Moonlight color.
At times, moonlight can have a bluish or silvery tint (compared to the rest of the sky). In fact, this is an illusion that appears due to the Purkinje effect - the perception of color by the human eye in the context of low light surrounding objects.
But during an eclipse, the Moon turns red due to indirect sunlight scattered by the atmosphere of our planet. An interesting fact is that today we see much less moonlight than our ancestors. This is due to the slow separation of the Earth from the Moon.
