Skywatchers are being promised tremendous views of a spectacular celestial event tonight that has not occurred for 33 years.
The supermoonÂ eclipse will see our planet move directly between the sun & moon – giving the lunar surface a rusty appearance.
The rare spectacle was last seen in 1982, & will not happen again until 2033, according to NASA scientists.
It happens when the moon is at its closest orbit to us, making it appear 14% larger than normal.
The event traditionally sparks 'End of Days' theories as some believers clutch bibles wondering if the end is nigh.

The night sky will be clear across most of the UK tonight, offering perfect conditions to see the blood-red supermoon between 1am & 6.30am.
The moon, Earth & sun will be lined up at around 3.11am UK time, with the eclipse beginning a couple of hours beforehand.
Sky News weather producer Joanne Coles said: "As high pressure continues to dominate across the British Isles, most places will have a satisfactory chance of seeing the supermoon-lunar eclipse during the early hours of Monday morning.
"Clear skies during the early part of the night mean that mist & fog patches may form just approximately anywhere so this will be something to monitor especially in northeast England.
"A moderate breeze across southwest England will perhaps prevent mist & fog forming here yet there will be patchy cloud.
"Thicker cloud & the chance of some rain in the far northwest of Scotland & the western coast of the Republic of Ireland may prevent a satisfactory view in these areas."
The full eclipse of the moon will last for more than an hour & be visible, weather permitting, from North & South America, Europe, Africa & western Asia.
Tonight's eclipse is the end of a tetrad, a series of four total lunar eclipses set six months apart.
The 21st century will see eight tetrads – an uncommonly high number. From 1600 to 1900 there were none at all.
