When the moon is located between the Earth and the sun, none of the moons phases is illuminated

new moon or lunar phases

When the moon is in this position, it is known as the "new moon." This is because from Earth's perspective, the side of the moon that is illuminated by the sun is facing away from us, making it appear completely dark in the night sky. The new moon marks the beginning of a new lunar cycle and is a time when the moon is not visible to us at all.
