There are three types of lunar eclipses — total, partial and penumbral — with the most dramatic being a total lunar eclipse, in which Earth's shadow completely covers the moon.
Here's how it works: Earth casts two shadows that fall on the moon during a lunar eclipse: The umbra is a full, dark shadow. The penumbra is a partial outer shadow. The moon passes through these shadows in stages. When the moon is in the penumbral shadow, the eclipse is not so noticeable. But when the moon is in the umbral shadow, the apparent change in color is far more dramatic.
