But, Novus Ordo Watch forgot to mention, it was a judaic, "6-sided" star over the manger.

.
Good call, Incredulous! The 6-sided star looked like 7 sides to me, but the top point is missing and replaced by a tail, implying what, a comet? A falling star?
.
This seems to indicate the 12th chapter of St. John's Apocalypse:
[4] And his tail drew the third part of the stars of heaven, and cast them to the earth: and the dragon stood before the woman who was ready to be delivered; that, when she should be delivered, he might devour her son. [5] And she brought forth a man child, who was to rule all nations with an iron rod: and her son was taken up to God, and to his throne. .
[1] "A woman": The church of God. It may also, by allusion, be applied to our blessed Lady. The church is clothed with the sun, that is, with Christ: she hath the moon, that is, the changeable things of the world, under her feet: and the twelve stars with which she is crowned, are the twelve apostles: she is in labour and pain, whilst she brings forth her children, and Christ in them, in the midst of afflictions and persecutions.
.
Fr. Gruner taught that the third of the stars falling from heaven has been interpreted by some exegetes as a third of the Church's priests who fall from their vocation. So now they've got their own monument hanging over the heads of the Holy Family in the manger scene, a 6-sided falling star right in front of the Egyptian obelisk in the center of Bernini's square.
