Babylonians, Egyptians, and Mayans had developed the first constellation maps and useful calendars but only Babylonians had perfected the calendar by studying of the motions of the Sun and Moon. Who were these wise men? The people before had a notion that the comets are heavenly omens. It is recorded in the Gospel that ‘Star of Bethlehem’ attracted attention of three wise men of the east. How King Herod or his advisors could not see such a momentous occurrence? Whether, the pairing had produced a dazzling object? In yet another remarkable event two brightest planets, Venus, and Jupiter came so close together that their pairing too appeared to merge into one but it is not known whether they had merged into one dazzling object. Astronomers now believe that in the year 7 ¼, the planets Jupiter and Saturn appeared to form a close paring. Gospel account says that King Herod did not know about the star until the wise men spoke about it. The passage reads, “Now when Jesus was born in Bethlehem of Judaea in the days of Herod the king, behold, there came wise men from the east to Jerusalem, Saying, Where is he that is born King of the Jews? For we have seen his star in the east, and are come to worship him”. Could it be possible that the story of the star has a basis in a real celestial event? In the Bible, the star is mentioned only in the Gospel of St Matthew 2:1-2. It is said that the star had attracted the attention of the Wise Men of the East. Star of Bethlehem in Biblical lore marked the birth of Christ. The story of Star of Bethlehem is a mingling of myth and reality. Whether Haley’s Comet was the Star of Bethlehem?
