(I had a very hard time deciding if this topic should go here or in the Astronomy section.)
My aunt, who (as she says) is Christian but does not believe Jesus was the son of God, sent me a link to a website about the star of Bethlehem:http://www.davidreneke.com/was-the-xmas-star-real/
The article speaks of the star of Bethlehem being a conjunction of Jupiter and Venus (and thus not an actual star).
However it seems like this conjunction is a very common occurrence, and indeed we had one in August 2014. Why then are these astronomers so amazed at what's happening here?
