The Star of Bethlehem: Astronomy Theories

Several sites I visited today had links to various astronomical theories on the Star of Bethlehem, thus in the spirit of the season, I give you the links:
The Star of Bethlehem by Colin Humphreys, originally printed in Science and Christian Belief , Vol 5, (October 1995): 83-101 – Humphreys advances the theory of a planetary conjunction of Jupiter & Saturn or a comet.
Revealing the Star of Bethlehem by Michael Molnar – Molnar’s website has a Q&A about his book on Jupiter as the Star of Bethlehem
What was the Star of Bethlehem? by Nigel Henbest in First Science – Henbest summarizes all the major astronomical possibilities for the Star.
Understanding the Christmas Star by Stephen Milton – Also a summary, but with more Bible exegises in combination with reviewing Molnar.
Happy reading!
