As you can see from the diagram below, a lunar eclipse happens when the Earth comes between the Sun and the Moon. When the Earth comes in between these two objects, its shadow covers the Moon (since it blocks the Sun). Such lunar eclipse diagrams are very important for students learning about space and outer space objects. By looking at the following lunar eclipse diagram, we can learn that the Moon does not have its light but shines because of the light that falls on it from the Sun. Now, since Earth has blocked the Sun, the Sun will cast the Earth's shadow on the Moon's surface.
