A Total Lunar Eclipse occurs when the Sun, Earth, and the Moon (in that order) line up and the Moon moves entirely through the Earth’s umbra, the darkest part of its shadow. As well as appearing dark, the Moon appears reddish during maximum eclipse. This is because Earth’s atmosphere bends some of the Sun’s light rays into Earth’s shadow, and because air preferentially scatters the shorter (bluer) wavelengths of that light, it produces a reddening effect while darkening the visible Lunar surface.
