A lunar eclipse is produced when the moon passes partially or totally into the shadow of earth.
This happens when the sun, the earth and the moon are almost aligned with the earth between the sun and the moon. It is a frequent phenomenon observable by everyone situated in the night side of the earth.
One must not get this phenomenon mixed up with a solar eclipse that also occurs when the three stars are alligned, but the moon is between the sun and the earth. A solar eclipse is more rare and only seen by people situated near a small area of earth (on the day side).
