Explanation:
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.
