New Moon. During this moon phase the sun is shining fully on the moon's far side and the near side remains dark. The only time it is visible from Earth is when a solar eclipse occurs.
The lunar cycle of phases is about 29.5 days. As the moon rotates and revolves around the earth, and the earth rotates and revolves around the sun, the shadows cast by the shifting positions of the moon and earth cause the moon to wane, wax, and "disappear". This is known as the lunar cycle.
Lunar eclipses always happen at the full moon phase. A lunar eclipse happens when the Moon is DIRECTLY lined up with the Sun and the Earth, so precisely that the Earth's shadow hits the Moon.

A lunar eclipse occurs when the moon passes through the Earth's shadow - this can only happen during the Full Moon phase.
That phase is called new moon. Moon may also be unobservable during lunar eclipse - it can only occur at full moon, because Moon has to be in line with Sun and Earth, behind Earth.
Full moon. On those rare occasions the moon drifts into earth's shadow the event is known as a lunar eclipse. The moon must be almost as full as it can possibly get just prior to a lunar eclipse.
