The Star Of Bethlehem

There is a phenomenon which is not extremely interesting to modern Astronomy, but which was important to ancient Astrologers for a long time, which is that as seen from that tiny point in space known as the Planet Earth, two distant celestial bodies can seem to Transit, which means that their position in the sky can seem to become superimposed, even though the angular size of celestial bodies is typically very narrow.

Some people might expect, that this will happen about as often, as the orbits coincide within our Solar System. But one reason why actual transitings are not that frequent, is the fact that the planets’ orbits are not truly coplanar. The orbits come close to lying in the same plane – which is loosely referred to as the plane of the solar system – but each orbit is tilted slightly with respect to the orbit of another planet. This means that while some transitings occur regularly, others only do so after hundreds, or even after thousands of years.

Jupiter “crowning Regulus” is a common phenomenon, which is tied to the period of the orbit of Jupiter. (This is also so common, because nobody expects Jupiter to pass directly in front of Regulus. )

But please, ask any Astronomer who you can get your hands on, ‘How often does Venus transit Jupiter?’ That should be good for a laugh.

Well in the year 2 B.C., both these events took place. Actually, Jupiter crowning Regulus is a dance which takes several months.

But, because Venus and Jupiter are the two brightest natural objects in the sky – unless we count the Moon and the Sun – If they become superimposed, and if Civilization is in a primitive, superstitious state, then Astrologers will take great note of a star seeming to form, which is twice as bright as any star they were familiar with.

Now, several years ago, I created a video using an Application called “Celestia“, which depicted this event. But I later felt that this video was so poorly orchestrated, that I deleted it myself. The actual act of Venus transiting Jupiter only took place within the last two seconds of that video, and the video had no sound. So I doubt that anybody was able to recognize what I was really trying to show the viewer.

But only today, I redid that video, and posted it to YouTube, as visible here:

This time, I narrated the Video with Audio. I invite the reader to watch it.

One fact which I’ve noticed about YouTube Videos and the way they play back, is that they could have been uploaded as 1920×1080 videos, but even after the viewer makes them full-screen, their resolution stays quite blurry for a good 30 seconds, until their real-time resolution keeps up with the viewer’s format-change, and switches to true High-Def.

The above video is an example of one, which I uploaded as a 1920×1080, and which should start playing back for the reader as such, about 30 seconds after he makes it full-screen.

Obviously, in order for this information to be taken seriously, the accuracy of the software needs to be questioned.

Questioning the accuracy myself, I have come across this information, not only in general, about how ‘Celestia’ works, but also, what some of the limitations of the software are.

My conclusion so far has been, that in order to depict the Year 1 A.D., its accuracy should be sufficient.
