The answer can be found in an interview The Washington Post did with physicist Aaron Adair, who is skeptical of the supposed star of Bethlehem. LINK. Dr. Adair wrote the book, The Star of Bethlehem: A Skeptical View, and a chapter for my upcoming anthology, Christianity in the Light of Science: Critically Examining the World's Largest Religion. I am doubly thankful for Adair's work. He not only used his expertise in science to debunk the faith-based claim of The Star of Bethlehem miracle, he also took the time to understand both the theology behind the supposed Bethlehem star and the apologetical gerrymandering surrounding that claim. His work is highly recommended.
