How is a new moon different from a lunar eclipse?
During a lunar eclipse, that same face of the moon is darkened, but not because it is experiencing night time. The earth is between the moon and sun, and the earth’s shadow darkens the face of the moon that we see. You could say that the entire surface of the moon is dark during a lunar eclipse. The far side is experiencing night time, and the earth side of the moon is darkened by earth’s shadow.
