occurs during a total lunar eclipse, as Earth lines up between the Moon and the Sun. When this happens, the only light that reaches the Moon’s surface is from the edges of Earth’s atmosphere. The air molecules from Earth’s atmosphere scatter out most of the blue light. The remaining light reflects onto the Moon’s surface with a red glow, making the Moon appear red in the night sky. This is the same effect that turns the sky pink, orange, and red at sunrise and sunset.
