On Saturday evening - just as Passover draws to a close - an eery blood colour will engulf the moon.
It is the third of four successive total 'blood-red' lunar eclipses, each followed by six full moons - an extremely rare 'Tetrad'.
Experts are predicting that the moon will be fully-obscured for five full minutes - and that the rare phenomenon will be visible across North America, Asia and Australia.
According to NASA the incredible alignment has only happened a handful of times in the last two thousand years.
The King James Bible predicts:
"The sun shall be turned into darkness, and the moon into blood, before the great and the terrible day of the LORD comes,"
[Joel 2:31].
We're doomed!
