Can you see a lunar eclipse?
Again, of course! Anyone with a view of the moon can see a lunar eclipse. The next four total lunar eclipses predicted for North America will be on April 15, 2014, October 8, 2014, April 5, 2015, and September 28, 2015.
Sometimes a full moon moves through Earth's shadow. This is a lunar eclipse ( Figure below ). During a total lunar eclipse, the moon travels completely in Earth’s umbra. During a partial lunar eclipse, only a portion of the moon enters Earth’s umbra. When the moon passes through Earth’s penumbra, it is a penumbral eclipse. Since Earth’s shadow is large, a lunar eclipse lasts for hours.

Partial lunar eclipses occur at least twice a year, but total lunar eclipses are less common. The moon glows with a dull red coloring during a total lunar eclipse ( Figure below ).
A lunar eclipse is shown in a series of pictures.
