|Our Moon turned red last week.
The reason was that during December 10, a
total lunar eclipse occurred.
The above digitally superimposed image mosaic captured the Moon many times during the eclipse, from before the
Moon entered Earth's shadow until after the Moon exited.
The image sequence was recorded over a
where the eclipse of the Moon was nearly, but not completely, total.
The red tint of the
eclipsed Moon was created by sunlight first passing through the Earth's atmosphere, which preferentially scatters blue light
(making the sky blue)
but passes and refracts
red light, before reflecting back off the Moon.
Differing amounts of clouds and
in the Earth's atmosphere make each lunar eclipse appear differently.
The next total lunar eclipse
will occur only in 2014.
