Seen through the branches of a pine tree, the eclipsed moon glows sunset red in the western sky over Clearwater before dawn Wednesday. Early risers across Florida and the United States were treated to a stunning lunar eclipse Wednesday, though clouds obscured it for some. Some viewers saw the moon turn orange or red in what is known as a "blood moon." The hue results from sunset-tinged light scattering off Earth's atmosphere. A lunar eclipse occurs when the Earth passes between the sun and moon, hiding at least part of the moon in its shadow.
