In the Americas alone more than one billion people in 35 countries could bear witness to the total lunar eclipse.

The only light that reaches the moon during a total lunar eclipse is light from the Earth's atmosphere, which projects onto the moon and gives it its reddish hue, USA TODAY previo

During the eclipse, the Earth passed between the sun and moon, blocking light from hitting the lunar surface, making the moon darker than usual. The moon turned a red hue, becoming a “blood moon,” due to the sunlight passing through Earth’s atmosphere before reaching its surface.
