A Blue-Banded Blood Moon
This image of a lunar eclipse shows a blue band across the Moon. The blue band is real, but it is usually hard to see. This high dynamic range image, taken from Yancheng, China, was processed to exaggerate the colors. The gray part of the Moon is its natural color, directly lit by sunlight. The upper left part is in Earth's shadow.
