The phase of the moon that is seen when the moon is located between Earth and the sun is called the new moon.
The phase of the moon that is seen when the moon is located between Earth and the sun is called the "new moon." During this phase, the side of the moon that is illuminated by the sun is facing away from Earth, making it appear mostly dark or completely invisible from our perspective. To determine this answer, you can recall the different phases of the moon and their positions relative to the sun and Earth. The new moon phase occurs when the moon is positioned between the sun and Earth, with the sun's light being blocked from reaching us.
