The unusual alignment of the sun, Earth and Mars
Tuesday night happened a week before the beginning of another
astrological event that some believe is associated with the end of the
world
Next week begins a cycle known as the 'Tetrad,'
which involves a series of four dark red 'blood moons.' At the end of
the cycle in September 2015, some believe the end of the world will
happen
The significance of the event is that it happens exactly a week before the first of four dark red 'blood moons,' which some Christians believe marks a cycle associated with the end of the world.
Also known as the 'Tetrad' since it involves four successive total 'blood-red' lunar eclipses each followed by six full moons, NASA has confirmed it started Tuesday night and will end on September 28, 2015.
In the 21st century tetrads are a frequent occurrence, with nine sets in total, but this has not always been the case.
From 1600 to 1900, for example, there were none at all.
The Book of Joel in the King James Bible makes a prophecy about the blood moons and the end of the world: 'The sun shall be turned into darkness, and the moon into blood, before the great and the terrible day of the LORD comes.'
