As the well - known tale in the Gospel of Matthew work , three Magi , or fresh men , followed the Star of Bethlehem to Jerusalem some 2,000 years ago . And after consulting withKing Herodof Judea , the men found newborn babyJesusin the little townspeople of Bethlehem . Whether such an event really happened in history is difficult to shew , but if it did , what was the Star of Bethlehem ?

This is a question scholars have long pondered , not just from a religious or historic linear perspective , but from ascientific one , too . spate of possibility have been proposed , from an galactic event to an astrological horoscope , but thanks to modern astronomy , scientist are suffer close to an answer .

Was the Star of Bethlehem a star, or something else?

" If what is in the New Testament is a diachronic account of something , then that historical account require an explanation , " David Weintraub , a professor of physical science and astronomy at Vanderbilt University in Tennessee , told All About Space in an email . " As an astronomer , you want an astronomical account . "

The Star of Bethlehem wasn’t a comet or a supernova

We roll in the hay thatHalley ’s Cometwas visible in the sky in 11 B.C. However , as the Magi trek toward Jerusalem and on to Bethlehem , it seems unlikely that they followed a comet because its position would have change as theEarth rotate , so the comet would not have led them in a single focussing . What ’s more , in the ancient world , cometswere often involve as forged omens .

" For Christmas cards , it stool a nice video having a comet and a rear end but in those days comet up in the sky were usually a forerunner of impending disaster , " Grant Mathews , a prof of theoretical astrophysics and cosmology at the University of Notre Dame in Indiana , told All About Space in an email .

Was the Star of Bethlehem a star, or something else?

We can also decree out novas andsupernovas . Either event would have result in a detectable leftover , but astronomers have not found anything that might date back to this time .

Furthermore , had the Magi followed one , they probably would have walked in a rope . " You ca n’t pursue a virtuoso from Baghdad to Jerusalem to Bethlehem , " Weintraub said . " mavin do n’t do that . They rise and set , and they do n’t model in the sky . "

Such an upshot would surely have been seen by others at the metre , too . Although nova are reportedly quite uncommon , you ’d still wait to find other historical explanation of a large , bright outcome in the sky .

Comets can be spectacular, such as Comet NEOWISE, seen here. But the Star of Bethlehem probably wasn’t a comet.

Other theories suggest a supernova in theAndromeda galaxyas the case , as depict in a 2005 study published in journalThe Observatory . Although it ’s potential to see the galaxy with the unaided eye , it would n’t have been possible to see a star going supernova and exploding within it — even with the helper of a telescope .

The “star” could have been an entire sky of stars

This leads us to one of two possible action . The first is that the Magi were make an astrological rendition of the sky . The fact that they postulate to ask Herod for direction when they go far hint they were not being led to their final name and address by a single bright objective .

Astrologywas widely used at the time , and with the Magi follow from Babylon , it ’s plausible that they were astrologers . And due to a finical alignment of planets and stars , they may have say a conceal signification among the stars , contribute them to King Herod . For exemplar , Jupiter ’s show could have been of bully significance here , as star divination associated the planet Jupiter with royalty , so the moon authorise it in the configuration of Aries on April 17 , 6 B.C. could have heralded the nativity of Christ .

" Modern uranologist do n’t put any credence in astrology , but ' modern ' is important in this context , " Weintraub say . " What ’s crucial is what masses thought 2,000 years ago . Astrology was a big good deal back then . The explanation I have found that makes the most sense is that it was astrological . "

Or, the “star” could have been a conjunction

The other , more astronomic explanation is that there was indeed a bright object in the sky — a colligation between planets and star . A conjunction takes place when two or more celestial body appear to meet in the night sky from our location onEarth . These events can go on every Nox in a standardized location for days or week . If the fresh men were to pursue the moment of colligation , it ’s possible they would have been run in a specific direction .

Astronomer Michael Molnar suggested that a conjunction theory might be correct in his book " The Star of Bethlehem " ( Rutgers University Press , 1999 ) . If the " star " was the result of a conjunctive ( and this historical event did really materialize ) , then there are a number of unlike alignments that could be the perpetrator .

Perhaps the most hopeful , and the one favored by Mathews , is an alliance ofJupiter , Saturn , themoonand the Lord’s Day in the constellation ofArieson April 17 , 6 B.C. This alignment fits with the story for a few reasons . First , this conjunction chance in the other morning time of day , which aline with the Gospel ’s description of the Star of Bethlehem as a rising morning star . The Magi also lost sight of the mavin , before fancy it come to reside in the place where infant Jesus lay in the stable . This could have been the result of the retrograde apparent motion of Jupiter , which means that it appear to change management in the night sky as Earth ’s orbit overtake it .

" Normally , planets move eastwards if you ’re follow them in the sky , " Mathews read . " But when they go through retrograde motility , they turn around and go in the commission that the stars climb and set at night [ westward ] . "

Two other continuative around a similar metre also look hopeful . One is the get together of Jupiter , Venusand the starRegulusin the configuration ofLeoon June 17 , 2 B.C. Without the assistance of a telescope , the two planet would appear as a single " star , " lustrous than Venus and Jupiter one by one . Another conjunction occurred in 6 B.C. , between Jupiter , Saturn andMarsin the constellation ofPisces . But neither of these latter two conjunctions match the description in the New Testament as tight as the conjunction that occur on April 17 , 6 B.C.

The mystery persists

Although scientists have rule out several possibilities , we may never get laid for sure what the Star of Bethlehem was or if it even really happened , exclude some remarkable archaeologic finding . But it ’s a interrogative that comes up year after twelvemonth , and it will keep to pique the involvement of scientist and historians alike for many years to come .

" Nothing in science is ever fount closed , nor is it in history , " Mathews say . " We may never know if the Star of Bethlehem was a colligation , astrological event or a fable to advance Christianity . Maybe it was simply a miracle . "
