Reading Passage

A lunar eclipse happens when Earth's shadow falls on the Moon. It can only happen at night, when the Moon is full or almost full.

The Moon does not make its own light. It shines because it reflects light from the Sun. Usually, sunlight reaches the Moon and comes back to our eyes.

During a lunar eclipse, Earth moves between the Sun and the Moon. Earth blocks some sunlight from reaching the Moon. Then Earth's shadow covers part or all of the Moon.

Sometimes the Moon looks dark. Sometimes it looks reddish or orange. This happens because some sunlight bends through Earth's air. The air scatters blue light away, but red light can still reach the Moon.

A lunar eclipse is different from a solar eclipse. In a solar eclipse, the Moon blocks the Sun from our view. In a lunar eclipse, Earth blocks sunlight from reaching the Moon.

Lunar eclipses are safe to watch with your eyes. You do not need special glasses. Many people can see the same lunar eclipse from different places on Earth.

A lunar eclipse is a quiet sky event. It helps us see how the Sun, Earth, and Moon line up in space.

Earth blocks sunlight and its shadow covers the Moon during a lunar eclipse.
