STAR OF BETHLEHEM MAY HAVE BEEN PLANETS JUPITER, VENUS

BLOOMINGTON, Ind. -- Early in the evening of June 17, 2 B.C., the brightest planets in the sky, Jupiter and Venus, merged into a dazzling "star" near the western horizon, according to calculations of modern astronomers. In countries to the east of what was then the kingdom of Judea, observers could have seen the fused planets as a beacon in the direction of Jerusalem.

Astrologers associated Jupiter with the birth of kings and Venus with fertility. The meeting of Jupiter and Venus took place in the constellation Leo the Lion, which the Old Testament of the Bible specifically associated with the Jewish people. And it happened near the brightest star in Leo, Regulus, most closely identified with kingship.

There has not been a brighter, closer conjunction of Venus and Jupiter in Leo so near to Regulus in the 2,000 years before or since.

Could this be the event that caused a group of astrologers called the Wise Men to travel to Jerusalem in search of a new king almost 2,000 years ago?

The Star of Bethlehem is mentioned only in a few verses of the New Testament's Book of Matthew (Chapter 2: 1-12), but it is one of the best-known parts of the Christmas story. A number of astronomers and historians have tried to determine what the unusual sight could have been.

Still there is no consensus. Explanations have been proposed since a suggestion by astronomer Johannes Kepler in the 17th century, but each contribution has seemed to raise as many problems as it solves.

Hollis Johnson, professor emeritus of astronomy at Indiana University, has collected a number of journal articles and other materials on the subject. "The question of the star is divided into two parts," Johnson noted. "One is astronomical: if a star was reported at the time, what was it? The other is astrological: why did the Wise Men associate the star with the birth of Jesus?"

There are three main theories to explain the Star of Bethlehem, Johnson said. One is a close approach by Jupiter and Saturn three times during a period of one year in 7-6 B.C. These conjunctions were not spectacular, Johnson said, but a triple conjunction is rare and was therefore significant to astrologers. A conjunction is a close approach between two celestial objects as seen from Earth. The closer the objects come to each other, the more visually impressive and astrologically significant the event is. This explanation is currently the most popular, because it makes the common assumption that King Herod the Great died in 4 B.C.

The second theory is the conjunction of Jupiter and Venus in 2 B.C. described earlier. For this explanation to be true, Herod must have died at a later date than is commonly believed.

The third theory involves something different -- a nova in the constellation Aquila the Eagle, recorded by the Chinese in 5 B.C. A nova is an enormous explosion at the surface of a star that is similar to a hydrogen bomb explosion, but much more powerful. The star temporarily brightens greatly, which we see as a nova. After a few days the star begins to fade, and after several months it is back to its original brightness (which may be quite faint).

"We don't know how bright the nova was, but it appeared to the ancients to be a new star," Johnson pointed out. If the nova were not bright, it would have been noticed only by those who studied the sky, such as astrologers. But it would have been significant to astrologers because it was new.

Apparently the Star of Bethlehem was noticed only by the Wise Men. There is no mention of a star in Luke's description of an angel announcing the birth of Jesus to shepherds in a field. According to Matthew, when the Wise Men arrived in Jerusalem they asked Herod, "Where is he who is born King of the Jews? For we have seen his star in the east and have come to worship him."

Herod had no idea what they were talking about and had to summon his advisers. The advisers told the Wise Men that according to prophecy, the Messiah would be born in Bethlehem.

If the birth of Jesus had been marked by a spectacular event such as a comet, which was considered an omen of great significance, Herod at least would have understood the Wise Men's reference to a star, and the shepherds would have been expecting something extraordinary to happen instead of being surprised.

The astronomical event that excited the Wise Men seems to have been significant only to them. This rules out the possibility of a conspicuous comet, which otherwise would be a good candidate. It implies that the Wise Men were astrologers (among other things), for such men would have known how to interpret the appearance of a celestial object that did not attract more than the casual attention of ordinary people.

To provide an astronomical explanation of the Star of Bethlehem, however, it is necessary to know precisely when the Wise Men made their journey to Judea. That turns out to be difficult to determine.

The most crucial fact is that Herod was king when the Wise Men arrived in Jerusalem. The difficulty is caused by disagreement among scholars about when Herod died. Roman record-keepers were normally scrupulous, but no specific record of Herod's death has been found. There is considerable indirect evidence that Herod died in 1 B.C. or 1 A.D., but the commonly quoted date for his death is 4 B.C. Scholars writing in the first and second centuries A.D. declared that Jesus was born between what we now call 4 B.C. and 1 B.C. They were living much closer to the event and had access to thousands of historical records.

In September of 3 B.C., Jupiter came into conjunction with Regulus, the star of kingship, the brightest star in the constellation Leo the Lion. Leo was the constellation of kings, and it was associated with the Lion of Judah. Just a month earlier, Jupiter and Venus had almost seemed to touch each other in another close conjunction, also in Leo. Then the conjunction between Jupiter and Regulus was repeated in February and May of 2 B.C.

Finally, on June 17, 2 B.C., Jupiter and Venus, the two brightest objects in the night sky except for the moon, came so close that their disks appeared to touch. This exceptionally rare event could not have been missed by observers such as the Wise Men.

The Bible does not mention how many Wise Men there were or where they came from. (The tradition of three Wise Men developed from the Bible's description of three gifts -- gold, frankincense and myrrh.) It is reasonable to suppose that their journey took months, however, since they had to cross several hundred miles of desert to reach Jerusalem. If they were in Jerusalem before dawn on Dec. 25, 2 B.C., they would in fact have seen Jupiter almost directly over Bethlehem to the south. They could have traveled the five miles to Bethlehem and presented their gifts that day. By then Jesus would have been a child living with his parents in a house, not a baby in a manger. There is a reference not to an infant (brephos in the Greek) but to a toddler (paidion), indicating that the birth itself had been some months before.

This would mean Jesus was born in the spring or summer, which makes a better setting for Luke's account of the shepherds. In December in Judea it was too cold for sheep to graze in the open fields, and they were kept under shelter during the winter months, especially at night.

There is no conflict with the traditional date of Jesus' birth, because Dec. 25 was an arbitrary choice. Early Christians changed the date numerous times to avoid discovery by the Romans when persecution of Christianity was at its height. When Christianity finally became the official religion of the Roman Empire, the festival of Christmas on Dec. 25 observing the birth of Jesus replaced the pagan festival of Saturnalia at that time, which had celebrated the "rebirth of the sun" as the days got longer following the winter solstice.

Designating Jupiter or the conjunction of Jupiter and Venus as the Star of Bethlehem eliminates a number of problems, but probably neither is the last word on the subject. So little is known historically about the period when Jesus was born that new information may well provide a more accurate picture of what happened.

Planets Venus And Jupiter The Star Of Bethlehem

BETHLEHEM, West Bank (Reuters) - Venus and Jupiter converged over the traditional birthplace of Jesus Tuesday night (March 8-9, 1999) in much the way some scientists say they may have done to

give rise to the story of the Star of Bethlehem.

As elsewhere on Earth for a limited time after sunset, the two planets appeared nearly to meet, together shining brighter than the other planets.

Church bells pealed after dark in Bethlehem, where according to Christian tradition a brightly shining star beckoned the Three Wise Men to the birthplace of Jesus 2,000 years ago.

"Because of the situation of Earth, Venus and Jupiter, you can see them close to each other," said Yigal Pat-El, head of the Israel Astronomy Association who watched the rare convergence -- called a conjunction -- through a powerful telescope in Givatayim near Tel Aviv.

"And something very interesting about this conjunction is that about 2,000 years ago the two planets were in conjunction, but so very, very close that perhaps you couldn't distinguish between the two planets with the naked eye," he said.

The stars are really 400 million miles apart.

"So it appeared as one big planet and scientists think that probably it's the star of Bethlehem that appeared in the same year that Jesus was born," he told Reuters.

3.Finally, an exploding star, or supernova, has been proposed to explain the Christmas Star. Some stars are unstable and explode with a bright blaze. However, historical records do not indicate that there were any supernovas at the time of the Lord's birth. There are only three bright supernova recorded in our galaxy:

Chinese star, 1054 A.D. (now the Crab nebula)

Tycho's star, 1572 A.D.

Kepler's star, 1604 A.D.

Ancient Evenings

IN 2946 B.C. a star in the constellation Taurus went supernova.

When the light from that explosion finally reached Earth 4,000 years later, in 1054 A.D., some Chinese astronomers wrote down their observations. What they saw was an unparalleled stellar phenomenon. For 23 days light from this supernova was visible in the daytime sky. It was twice as bright as the planet Venus. For 653 days afterward it could be seen at night as though it were a new star. The Chinese referred to it as a "guest star." Today it's known as the Crab Nebulae, a gaseous cloud.

The Crab Nebula

The Crab Nebula is a supernova remnant. Embedded within it is a radio pulsar.

•The supernova was observed in 1054 A.D.

•The supernova event was visible to the naked eye in the daytime; it was as bright as Venus.

•The filaments in the nebula are seen to be expanding at 1000 km/sec.

•The total mass of ejected material is about 0.1 solar masses.

•The distance to the Crab Nebula is about 3500 light years.

•The diameter of the remnant is 6 light years.

•A pulsar was discovered in the center of the nebula in 1969.

•The neutron star in the center of the Crab rotates 33 times per second.
