Description : (La description de cette image n'existe qu'en anglais)
(01/20/2000) --- In this lunar eclipse viewed from Merritt Island, Fla., at midnight, the full moon takes on a dark red color because it is being lighted slightly by sunlight passing through the Earth's atmosphere. This light has the blue component preferentially scattered out (this is also why the sky appears blue from the surface of the Earth), leaving faint reddish light to illuminate the Moon during the eclipse. Eclipses occur when the Sun, Earth and Moon line up. They are rare because the Moon usually passes above or below the imaginary line connecting Earth and the Sun. The Earth casts a shadow that the Moon can pass through –when it does, it is called a lunar eclipse
