... Lunar eclipse- occurs when the moon, always a full moon, passes through the shadow of Earth. Earth blocks the sun’s light from reaching the moon, but the moon does not look black. Instead, it looks red. This is because the Earth’s atmosphere bends the red light, which then reflects off the moon. Ref ...
