A '''lunar eclipse''' occurs when the [[moon]] passes through the [[shadow]] cast by the [[earth]].  Eclipses can be partial or total: in a total eclipse, the earth's shadow completely blocks the sun's direct light to the moon; in a partial eclipse, some of the moon is still illuminated.

Lunar eclipses can only occur during a [[full moon]],  since the geometry of the situation requires that the earth be directly between the sun and moon — meaning that before and after the eclipse, the face of the moon we see is fully illuminated.
