The total lunar eclipse, which takes place when the moon passes behind Earth and into its shadow, will last one hour and 43 minutes from July 27.
The eerie lunar phenomenon is set to turn the sky an orange glow from around 9.30pm UK time, which some fear is an omen the earth faces imminent destruction.
It is caused when the moon travels through the earth’s umbra and blocks direct sunlight from illuminating its surface.
The apocalyptic belief linking the blood moon to the world’s end stems from interpretations of the Christian Bible.
Christian ministers John Hagee and Mark Blitz preached that a tetrad – four consecutive lunar eclipses – indicates the end of the world is nigh.
But the first eclipse in their prophecies occurred on April 14, 2014, with further Blood Moons on October 8, 2014, April , 2015 and September 28, 2015 – with the world still spinning on its axis.
The doomsday preachers claim this portent of armageddon is prophesied in Acts 2:20 and Revelation 6:12 of the holy book.
The Book of Joel Acts 2:30-31 says: “And I will show wonders in the heavens and in the earth, blood, and fire, and pillars of smoke.
“The sun shall be turned into darkness, and the moon into blood, before the great and the terrible day of the Lord come.”
Another passage from Revelations reads: “And I beheld when he had opened the sixth seal, and, lo, there was a great earthquake; and the sun became black as sackcloth of hair, and the moon became as blood.”
But astronomers and others have dismissed the beliefs as ludicrous.
The moon’s red glow is attributed to the dispersal of sunlight through the Earth’s atmosphere, which is known as Rayleigh scattering.
The same phenomenon takes place during sunrises and sunsets and turns the sky blue.
Friday’s total lunar eclipse will be the longest so far this century – although some fear it could spark anger on earth.
Astrologer Jamie Partridge told Bustle: “The lunar eclipse July 2018 astrology is mainly influenced by Mars, making this an emotionally challenging eclipse.
“Mars’ anger and frustration could easily turn to reckless actions because of a harsh aspect to Uranus.
“A more gentle influence from Saturn will make it a little easier to calm down, and some fixed stars give patience and decisiveness in a crisis.”
