The Moon is eclipsed when it moves into the Earth's shadow. Below are several images of lunar eclipses over the years. The ruddy colors are caused by light grazing the earth's atmosphere, just as in sunsets.
The lunar eclipses of 2003-11-08 (on the left) and 2008-02-20 (on the right -- both also shown below) were fairly similar. During both the Moon was positioned near the southern edge of the Earth's shadow at mid-eclipse. Due to differences in the Moon's libration, the Moon's face was tilted to slightly different orientations during each eclipse. The tilt provided just enough of a difference in the views to produce a natural stereo pair. (The resulting stereogram appeared on p. 68 of the November 2013 issue of Popular Science magazine.)
To see the Moon in 3-D, sit about a foot from your monitor and look into the distance between the two above images of the Moon. When your eyes shift to the alignment normally used for viewing objects at a distance, the two images will fuse to form a third and you will see the Moon as the 3-D sphere it really is. (If you have a pair of red/blue glasses, the anaglyphic version might be easier to view.) ©2008
