A Time-Lapse Lunar Eclipse

During last week's lunar eclipse , our Moon appeared to disappear. As the Earth moved between the Moon and the Sun, the Earth's shadow fell on the moon, making it quite dark . In the above picture the Earth's rotation, multiple exposures, and digital enhancements are used to create a time-lapse effect that dramatizes how the Moon looked as it faded out and re-appeared during the three hour lunar eclipse . As the Earth's shadow engulfed the Moon , the lunar images became less and less bright, practically disappearing during totality . At this time, the Moon, which normally shines by reflecting direct sunlight, shone only by sunlight refracted through the Earth's atmosphere . The next total lunar eclipse won't be visible from Earth until 2007 .
