Eclipses

Astronomers now know that solar eclipses occur during a new moon phase, and a lunar eclipse occurs during a full moon phase when the Sun, the Moon, and the Earth are all in perfect alignment, which does not occur with every new and full moon because of the moon's tilt. In a solar eclipse, the Moon blocks the Sun’s light to the Earth; and in a lunar eclipse, the Earth blocks the Sun’s light to the Moon.
