Stargazers on nearly one half of the world witnessed a total lunar eclipse overnight, as a rare cosmic lineup caused the moon to turn a shade of red.

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.

As the moon reflects the sun's light, the shadow dims the moon's glow. During the peak of a total lunar eclipse, the moon takes on a bit of a reddish hue as any leftover sunlight making it to the moon's surface is scattered by our earth's atmosphere.
