Similarly, those who have investigated what the Star of Bethlehem might have been in the natural order, likewise conclude that it was not a star, or even a stellar event, like a supernova. Rather, for those who have taken this approach the best case is made for a conjunction of planets – their apparent merging from our perspective. The ancients attributed great significance to the planets, and their conjunction conveyed meaning about the history of kings and nations. What we take as superstitious astrology today, the ancients saw as divine action in the heavens conveying knowledge to mankind. For the Christian, God's Providential use of an otherwise erroneous worldview to bring these Gentile Kings or Magi to Bethlehem would be a possible explanation of the star. On this basis, it is not uncommon for planetariums to have Star of Bethlehem presentations at Christmas time, to illustrate what the “star” might have been.
