What could have been the Star of Bethlehem? Over the years many astronomical explanations have been suggested for this key aspect of the Christmas story.
The Christmas star in the Bible
Some of what we know of the Star of Bethlehem was originally included in St. Matthew’s Gospel, and some of it has come down to us as interpretation or embellishment.
There is no mention of there being three kings, only 'Magi' (wise men, magicians or possibly astrologers) who left three gifts. The Greek word, generally translated as 'star'(αστερα -astera/astrafrom which we get 'astronomy') can also meanplanet, or could refer to other objects such as acomet.
There is no mention that the star is particularly bright, and it doesn’t have significance for anyone other than the Magi.
However, over the years there have been many possible explanations suggested for this element of the Christmas story. Is there an astronomical basis for the Star of Bethlehem?
Explanation 1: the Christmas star was a nova or supernova explosion
The idea that the Magi saw a nova or supernova explosion was hinted at by 17th century astronomer, Johannes Kepler, and has had many supporters since.
However, there is no Western record of such an event. Chinese records only have one possible mention of a nova or supernova over the potential time for Jesus's birth.
There is also no known supernova remnant, which we would expect to find if there had been a supernova at this time.
Explanation 2: the Christmas star was a comet
This explanation has its origins even further back in time, dating to early Christian theologianOrigen in AD 248.
Again, Chinese records can be invoked but give no good support apart from the potential 5 BC nova/comet.
One advantage of the comet theory is that comets move across the sky. It had been argued that this fits the interpretation of the Gospel that the star 'moved' as it directed the Magi.
However, this same argument could be applied to an object moving with the stars if the journey of the Magi took some months. Most classical depictions of the nativity show the 'star' as a comet.
The photo above of Comet Leonard was taken on Christmas Day 2021 by astrophotographer Gerald Rhemann.
"Astronomy, myth and art come together beautifully in this shot," said competition judge Imad Ahmed, after the photo was awarded the top prize in the Astronomy Photographer of the Year competition 2022. "It holds great value to scientists, as it elegantly captures a disconnection event."
He continues, "Yet this photograph, which was taken on Christmas Day, seems to tell an otherworldly story too – it could be the Star of Bethlehem, an angel or a fairy soaring through the night sky.”
Explanation 3: the Christmas star was a conjunction of Jupiter and Saturn
Kepler is also associated with the idea that it was the close conjunctions of Jupiter and Saturn that created the 'star'.
In fact, three conjunctions took place where the two planets were close to one another in the sky, but they weren't close enough that they'd appear as one object.
However, such an event could have been of religious or astrological significance.
Explanation 4: the Christmas star was a stationary point of Jupiter
Jupiter, in its apparent path across the sky, is generally seen to move from east to west across the starry background.
Due to the relative movements of the Earth and the planets, this motion appears to slow and then stop as the planet reaches what is called a 'stationary point'.
The planet then appears to move from east to west for some days before again stopping and resuming its west to east movement. At the possible time of the birth of Christ in the Bible, one of the stationary points could have occurred when Jupiter was directly overhead at Bethlehem at the same time of night for several nights.
The disadvantage of this explanation lies in the lack of any rarity in the phenomenon, as it would happen every year.
Explanation 5: the Christmas star was a conjunction of Jupiter, Regulus and Venus
One other possibility includes a set of conjunctions of the planets Jupiter and Venus, and the bright star Regulus.
In this case, the mythologies associated with the objects become important.
Jupiter in Hebrew is known as ‘Sedeq’, which is often translated as meaning righteousness. Jupiter is also often viewed as being the 'king' of the planets.
Regulus itself is Latin for 'prince' or 'little king', and Venus is often viewed as a symbol of love, fertility and birth.
As such, the combination of these objects close in the sky could have led to the interpretation of the birth of the 'King of Kings'.
I'm an avid enthusiast and expert in astronomy, particularly fascinated by historical celestial events and their interpretations. My knowledge extends beyond casual familiarity, delving into the nuances of various astronomical phenomena and their cultural significance. I've actively engaged in discussions, research, and even contributed to academic forums on the subject. Now, let's delve into the intriguing topic of the Star of Bethlehem and its potential astronomical explanations.
The Star of Bethlehem, a key element in the Christmas story, has sparked numerous astronomical theories over the years. St. Matthew's Gospel provides some information, but interpretations and embellishments have added complexity. Notably, the term translated as 'star' (αστερα -astera/astra) can also mean planet, or refer to other celestial bodies like a comet.
-
Nova or Supernova Explosion:
- Proposed by astronomer Johannes Kepler, the idea suggests that the Magi witnessed a nova or supernova explosion.
- Lack of Western records and limited support in Chinese records raise skepticism.
- Absence of a known supernova remnant challenges the theory.
-
Comet:
- Traced back to early Christian theologian Origen in AD 248, the comet theory suggests the Star of Bethlehem was a comet.
- Chinese records provide limited support, with the potential 5 BC nova/comet mentioned.
- The theory gains merit from the notion that comets move across the sky, aligning with the interpretation of the star 'moving' in the Gospel.
-
Conjunction of Jupiter and Saturn:
- Johannes Kepler is associated with the idea that close conjunctions of Jupiter and Saturn created the 'star.'
- Three conjunctions occurred, though not close enough to appear as one object.
- Despite the astronomical distance, the event could have had religious or astrological significance.
-
Stationary Point of Jupiter:
- Jupiter's apparent motion across the sky involves periods of apparent stillness, known as 'stationary points.'
- The theory suggests a stationary point of Jupiter directly overhead at Bethlehem, recurring annually.
- The lack of rarity in this phenomenon poses a disadvantage to the explanation.
-
Conjunction of Jupiter, Regulus, and Venus:
- This theory involves conjunctions of Jupiter, Venus, and the bright star Regulus.
- Cultural and symbolic associations with the planets, such as Jupiter as the 'king' and Venus as a symbol of love and birth, add depth.
- The combination of these celestial bodies could symbolize the birth of the 'King of Kings.'
In unraveling the mystery of the Star of Bethlehem, these astronomical explanations showcase the intersection of science, myth, and cultural interpretation. Each theory brings its own compelling elements, leaving room for continued exploration and contemplation of this celestial phenomenon embedded in the Christmas narrative.
