"Michael Molnar announced 10 years ago his conclusion that the Star of Bethlehem was in fact a double eclipse of Jupiter in a rare astrological conjunction that occurred in Aries on March 20, 6 BC, and again on April 17, 6 BC. ... Mr. Molnar believes that Roman astrologers would have interpreted the double-eclipse as signifying the birth of a divine king in Judea." However, astronomical software such as Stellarium shows that on March 20, the occultation of Jupiter by the Moon could not be seen from Rome, as the Moon passed by the planet without obscuring it. Furthermore, the event on April 17 began when Jupiter was 38 degrees above the horizon, at 2pm, i.e. in daylight, so it is extremely unlikely that this event would have been seen either.
