Which phase does the moon receive sunlight only on a side facing away the earth?

The phase in which the moon receives sunlight only on the side facing away from the Earth is called the "new moon." During this phase, the illuminated side of the moon is not visible from Earth, making it appear dark. The new moon occurs when the moon is positioned between the Earth and the sun, aligning them in such a way that the sunlit side is turned away from us.
