For years, scientists have looked, with little success, to astronomical records for an explanation of the magical star that guided the Magi to Christ’s manger. Molnar argues in his book that the Star of Bethlehem was not a star at all, but rather a regal portent centering around the planet Jupiter that was eclipsed by the moon. He bases this theory on the actual beliefs of astrologers, such as the Magi, who lived around the time of Christ. Using clues from astronomy, astrology, and history, Molnar has created a provocative, fascinating theory on the Christmas Star., weaving together an intriguing scientific detective story which resolves one of the world’s greatest mysteries: The Star of Bethlehem at the birth of Christ.
