A friend once wrote a short story that I think he may have plagiarized. I don't remember all the details, but the gist was that a crewman on a spaceship killed his crew mates and blew up the ship, and the explosion was visible from earth; in fact, it became the legendary star which the wise men followed to Bethlehem. Some of the particulars may have been changed a bit, but the most important points were the spaceship exploding and the wise men seeing it.
Note: It is entirely possible that my friend did invent the story himself. If this is the case, there is no correct answer to this question.
Note 2: It should be obvious that this question is not a duplicate of the one linked here (Short story where the Bethlehem Star proves to be a Supernova and an expedition visits its remains), as the plot is quite different. The star is not a star, it is a spaceship explosion. The story ends with the explosion being seen from earth, and no expedition is sent to investigate it.
