Last night, right before I went to bed, the moon was full, lighting up the entire ground. It was like daylight. Then, I got up and walked outside during the eclipse, the moon was hazy, then half light and half darkness, then dark.
The moon does not have a light of its own. It simply reflects the light from the sun.
The shadowing was gradual, but when the earth came between the sun and the moon, the moon was dark.
The world gets between the sun so there is no reflection of the moon.
Spectacular remarkable development!
