The first total lunar eclipse in more than two years lit up the sky last night as humanity, forever fascinated with the Earth’s only natural satellite, watched.

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.

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