The Blood Moon

The total lunar eclipse of Oct. 8 was visible to observers in North America, western South America, parts of East Asia, Australia and other parts of the Pacific, weather permitting. The  lunar eclipse is also the second of four consecutive total eclipses of the moon that make up a unique "tetrad."

During the eclipse, the moon passed into the darkest part of Earth's shadow, which caused the moon to glow with an eerie copper color. This color shift has caused some people to dub the natural satellite a "blood moon" during total lunar eclipses. The moon's temporary color also created an incredible, unique sight to behold for photographers on the ground.
