Earth’s shadow will block most of the light that illuminates the lunar surface, creating what is known as a blood moon.

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.

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.
