A National Geographic article published a few years ago describing a real celestial event which took place at the time of the birth of Jesus reminded me of Risto Santala’s explanation in his book, "The Messiah in the New Testament in the Light of Rabbinical Writings". He wrote about a conjunction of major planets that took place which could have led the wise men from the east, to Israel.
Santala reports that in 1603, Johannes Kepler observed a conjunction of Jupiter and Saturn in the constellation of Pisces; he observed a "new, particularly brilliant and strangely colored star between Jupiter and Saturn, which soon faded." Kepler suggested that the Star of Bethlehem could have been such an event. Later, Alfred Edersheim wrote, "There can be no doubt that the most remarkable conjunction of planets -- that of Jupiter and Saturn in the constellation of Pisces, which occurs only once in 800 years -- did take place no less than three times in the year 747 A.U.C., or two years before the birth of Christ (in May, October, and December). This conjunction is admitted by all astronomers."
Santala writes, "The constellations of the zodiac were generally identified with different nations, Pisces, for example, being considered the patron constellation of Syria and Palestine, and the revealer of the End Times. Saturn was associated with Palestine in Babylonian astrology, whereas Jupiter was the royal planet, foreshadowing a political Golden Age. Thus, when Jupiter conjoined with Saturn in Pisces it was obvious that the Ruler of the End Times had been born in Palestine."
Whether or not this was the "star" the wise men saw is debatable, but it strongly suggests that a real and significant celestial event did take place roughly at the time of the birth of Jesus. As millions around the world are celebrating His birth this week, we ought to remember that one purpose for which God created the stars was, "for signs." [Genesis 1:14]
