About New Moon
In astronomy, the new moon is the first lunar phase, when the Moon and Sun have the same ecliptic longitude.
At this phase, the lunar disk is not visible to the unaided eye, except when silhouetted during a solar eclipse.
Daylight outshines the earthlight that dimly illuminates the new moon.
