The change in its shadow is based on:::where the moon is in its orbit. We call this cycle the phases of the moon, and it occurs:::roughly once a month. At least twice a year, however, something quite different:::happens. The moon passes through the shadow cast by the Earth, causing it to look extremely:::unusual for a short period of time. From the earth, the moon will appear to:::darken and turn a deep red before eventually returning to normal. This is called a lunar:::eclipse. If we were to look at what happens from space during an eclipse, it would go:::something like this. First, the moon passes through what's called the penumbra,:::where the sun's light is only partially obscured. This results in only a slight darkening:::of the moon. As the moon continues along its path, however, it enters what's:::called the umbra, where all direct light from the sun is blocked. But if the sun is blocked,:::why does the moon turn red? When light from the sun goes by the side of the Earth,:::it passes through a long and thick layer of Earth's atmosphere. Shorter wavelengths:::of sunlight, like blue, are scattered by the atmosphere, so by the time the light has finished:::its trip to the moon, more of the longer wavelengths, like red, are left over.:::On the Earth, the same thing happens at sunset as the ground you stand on gradually passes:::into night. As the eclipse ends, the moon leaves the umbra, returns:::to its normal color, and then leaves then penumbra, brightening and resuming its original:::cycle. Overall, the whole process lasts only from a few minutes to a few hours,:::so you'll have to be quick if you want to see it. But, as long as you're willing to stay awake,:::you'll catch the moon as you won't see it too often.:::[music, beeping]:::[music, beeping]:::[music]:::[silence]::: 00.01:::04.12:::08.22:::12.31:::16.42:::20.52:::24.60:::28.66:::32.71:::36.74:::40.77:::44.87:::49.02:::53.16:::57.27:::61.37:::65.46:::69.54:::73.59:::77.65:::81.68:::85.71:::89.72:::93.80:::97.92:::102.01:::106.06::: Arial:::Arial:::Arial:::Arial:::Arial:::Arial:::Arial:::Arial:::Arial:::Arial:::Arial:::Arial:::Arial:::Arial:::Arial:::Arial:::Arial:::Arial:::Arial:::Arial:::Arial:::Arial:::Arial:::Arial:::Arial:::Arial:::Arial::: 14:::14:::14:::14:::14:::14:::14:::14:::14:::14:::14:::14:::14:::14:::14:::14:::14:::14:::14:::14:::14:::14:::14:::14:::14:::14:::14::: Plain:::Plain:::Plain:::Plain:::Plain:::Plain:::Plain:::Plain:::Plain:::Plain:::Plain:::Plain:::Plain:::Plain:::Plain:::Plain:::Plain:::Plain:::Plain:::Plain:::Plain:::Plain:::Plain:::Plain:::Plain:::Plain:::Plain::: 65535, 65535, 65535:::65535, 65535, 65535:::65535, 65535, 65535:::65535, 65535, 65535:::65535, 65535, 65535:::65535, 65535, 65535:::65535, 65535, 65535:::65535, 65535, 65535:::65535, 65535, 65535:::65535, 65535, 65535:::65535, 65535, 65535:::65535, 65535, 65535:::65535, 65535, 65535:::65535, 65535, 65535:::65535, 65535, 65535:::65535, 65535, 65535:::65535, 65535, 65535:::65535, 65535, 65535:::65535, 65535, 65535:::65535, 65535, 65535:::65535, 65535, 65535:::65535, 65535, 65535:::65535, 65535, 65535:::65535, 65535, 65535:::65535, 65535, 65535:::65535, 65535, 65535:::65535, 65535, 65535::: 0:::0:::0:::0:::0:::0:::0:::0:::0:::0:::0:::0:::0:::0:::0:::0:::0:::0:::0:::0:::0:::0:::0:::0:::0:::0:::0::: 0:::0:::0:::0:::0:::0:::0:::0:::0:::0:::0:::0:::0:::0:::0:::0:::0:::0:::0:::0:::0:::0:::0:::0:::0:::0:::0::: 0, 0, 0 360 4:::4:::4:::4:::4:::4:::4:::4:::4:::4:::4:::4:::4:::4:::4:::4:::4:::4:::4:::4:::4:::4:::4:::4:::4:::4:::1::: 40 90 en unkeyed 15:::15:::15:::15:::15:::15:::15:::15:::15:::15:::15:::15:::15:::15:::15:::15:::15:::15:::15:::15:::15:::15:::15:::15:::15:::15:::15::: 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
