What caused the Star of Bethlehem?

(WVLT) -- Many astronomers believe the Star of Bethlehem revealed the birth of Jesus.

Christians view it as a miraculous sign while others say it also fulfilled a prophesy.

Some say it was a supernova, others a comet.

In 1595, German Astronomer Johannes Kepler discovered a conjunction with Saturn and Jupiter. But many others discounted it as the Bethlehem Star over time and there were no records indicating a supernova at that time between 4 and 1 BC.

Another theory is the alignment of Jupiter and Venus. This phenomena also happened on August 27, 2015.

These are just theories, and so far nothing has been fully accepted by scientists or astronomers.

If you accept the story told in the Bible, then the star couldn't have been a natural apparition but a supernatural sign and only accepted through faith.
