During the new moon phase, the moon is positioned between the Earth and the sun. This means that the side of the moon that is facing the Earth is not being directly illuminated by the sun. As a result, the moon appears very faint or even invisible to the naked eye.
It's important to note that the moon is still present in the sky during the new moon phase, but its position and lighting conditions make it difficult to see. As the moon progresses through its phases, it逐渐 moves away from the sun's direct line of sight and begins to reflect more sunlight. This gradual increase in reflected sunlight makes the moon more visible until it reaches the full moon phase.
