Blood Moon 2014 - Lunar Eclipse Online
On October 8, 2014, there will be a total lunar eclipse. It will be the second of four consecutive total eclipses in a series, known as a tetrad (the remaining 2 eclipses will take place on April 8, 2015, and September 28, 2015).
Due to its reddish color, a total eclipse of the moon is sometimes referred to as a blood moon. In addition, in the 2010s the media started to associate the term "blood moon" with the four full moons of a lunar tetrad, especially the 2014-2015 tetrad coinciding with the feasts of Passover and Tabernacles. A lunar tetrad is a consecutive sequence of four lunar eclipses, spaced six months apart.
Join NASA experts on Oct. 8 to observe 2014's second total lunar eclipse. The eclipse will begin just after 4 A.M. EDT and continue until sunrise. A map of world eclipse visibility is located here.
A lunar eclipse happens when the Earth casts a shadow that blocks sunlight that normally reflects off of the moon. A total lunar eclipse can only happen when the sun, Earth and moon are perfectly aligned. During the time of total eclipse, the moon will often look reddish due to red and orange light being scattered by the atmosphere. This eerie, harmless effect has earned the tongue-in-cheek nickname "blood moon."
It will be one of 8 tetrads during the 21st century AD. As with all eclipses, it is probable that the moon will appear to be a dark red color during the eclipse due to the refraction of sunlight through the Earth's atmosphere. This is the same effect that causes sunsets to appear red.
