WAS THIS THE REAL CHRISTMAS STAR?
The question is more telling than the answer
In the waning weeks of 2020, as the world grew darker, we
were treated to a rare astral event as Jupiter and Saturn moved closer and
closer in each successive evening sky. The slow-mo spectacle provided a
pleasant diversion from the grim situation on Earth. On December 21, the winter solstice, the two
planets appeared in their closest conjunction in 800 years, nearly merging into
a single brilliant star. Just before Christmas. Could this be a repeat of the planetary
alignment that created the Christmas “star” more than two thousand years ago?
The astrological sign that led the Magi to Jesus?
The motions of the planets are well documented, and their
orbits can be rewound to precisely determine the dates of prior conjunctions.
But pinpointing the time when Jesus is more difficult.
When was Jesus born?
The date is hazy. The Gospels of Luke and Matthew state that
Jesus was born during the reign of Herod the great. The historian Josephus said
that Herod’s death occurred after a lunar eclipse and before Passover.
Therefore, most scholars believe he died in 4BC, when there was a lunar eclipse
29 days before Passover. But the 4BC lunar eclipse that was used to peg Herod’s
date would not have been so visible in Judea. There were other lunar eclipses during
that era, the most spectacular of which was a total eclipse in January of 1 AD.
This would push the potential date of
Jesus’s birth as late as that year (Anno Domini, the year of Our Lord), but
probably a few years earlier, perhaps as early as 6 BC.
Another time point to consider is the première event of
Jesus’s ministry, his baptism by John the Baptist. Luke’s Gospel says Jesus was
“around” 30 years old when he began his ministry and that John preached during
the 15th year of the reign of Tiberius. Counting backward from that
year, which is recorded in history, would backward would arrive at a birth year
of 1 or 2 BC for Jesus, depending on his exact age. “Around” 30 could be 28 or
32.
What Did the Magi see?
The Christmas star and the quest of the Magi appear very
briefly in the Bible, and only in the Gospel of Matthew. Wise men came to
Jerusalem from “the East,” asking, “Where is the one who has been born king of
the Jews? We saw his star when it rose and have come to worship him.” King Herod
was disturbed to hear news and consulted his advisors, who informed him that
according to scripture, the Messiah would be born prophesied in Bethlehem.
Herod summoned the Magi to his court to learn the exact date that the star had
appeared. He sent them to Bethlehem and instructed them to return to him when
they found the child. When they set out on the 6-mile trip south from Jerusalem
to Bethlehem, they were overjoyed to see that same star rise before them and
stop over the place where the child lay.
What Astral Events are Candidates for the Christmas Star?
In the 17th century, astronomer Johannes Keppler
suggested that a convergence of Jupiter and Saturn could have been the bright
star guiding the Magi. There were three conjunctions of Jupiter and Saturn in 5
BC, but none close enough to result in a star. Nevertheless, the unusual
stellar event could have had astrological significance for the Magi, who were
familiar with Jewish scripture. Another candidate would be a conjunction
between Jupiter and Venus. In 2 BC, those planets came close enough together to
form a single star. Venus is much brighter than either Saturn or Jupiter (The
picture at the head of this article is a photo I recently took at the dawn of
Christmas Eve), so that convergence would have been much brighter than the one
we just witnessed. But planetary convergences are fleeting and would not have
remained in the sky during the two months required for the Magi to travel from
Persia to Jerusalem.
It is much more likely that the Christmas Star was a comet.
The records of Chinese astronomers document a “broom star” (tailed comet) that
appeared in the sky for 70 days in 5 BC. The Magi could have first seen that
comet in the eastern sky just before dawn. Comets typically move across the sky
at one or two degrees per day, so in two months’ time, it could easily have
appeared in the south in the morning sky. Thus, as the Magi set out in the
early morning to travel south, the comet would have been before them, its tail
vertically above, so that its head pointed toward Bethlehem.
What does our curiosity about the Christmas Star say about
us?
The possibility that we could be witnessing a re-creation of
the Christmas star resonated with a hope that that it could be a sign of better
times. It had a nostalgic appeal to believers and non-believers alike. There is
a difference between knowing and believing. A tragedy may be impossible to
believe, despite incontrovertible facts. We may fear something like a bogeyman
under the bed, even when we can see that it is not there. Sometimes we believe
some wonderful thing will happen, even though it clearly seems impossible. When
there is no way of knowing for certain, we seek confirmatory evidence, sometimes
as small as finding cookie crumbs on an otherwise empty plate on Christmas
morning next to the stockings we had hung the night before.
What is the answer to the question?
A conjunction of Jupiter and Saturn is very unlikely to be
the event that led wise men to seek Jesus. But the planetary convergence at the
end of 2020 led me to study scripture and astronomy. I did not gain significant
new knowledge about the Christmas Story. But I was awed by the regularity of
planets that have followed the same orbits for millions of years. I recalled a
line from one of my father’s favorite poems, Desiderata. “The universe is
unfolding as it should.” I am watching the planets move further apart each
evening, knowing that long after I have departed this world, they will appear
together again. Observing the rhythm of the solar system heightens my awareness
of my pitiful insignificance, yet paradoxically leaves me empowered and soothed
by that comprehension.
So, for me, the answer to the question is yes. This was my
Christmas Star.
