The mystery of the rings of the binary star WR-140 is solved.

The rings around binary star WR-140 formed because the O-type, very hot star travels across the Wolff-Ryat star's dust and gas. Or the thing that causes those rings is the solar winds of those stars colliding. And that forms the high-energy gas that causes the ring-shaped structure.

So the rings have no alien origin. But the fact is that also cepheid stars or lone Wolff-Ryat stars can send gas rings around them. When the cepheid star pulsates its energy production changes. 

When the size of the star decreases pressure and temperature inside it increases. And nuclear fusion will increase. Then that rising energy production pushes the core of the star outwards. And even if the size of the star decreases when the pressure inside it decreases the high-energy gas continues its way through the universe. 

Or some neutron star or pulsar can form that kind of structure. When the energy pike from a pulsar hits the star. That thing increases its energy production. Also, things like white dwarfs that erupt at intervals of a certain time can form rings around the system.  In that case, rings can form straight from the white dwarfs. Or they can form when energy hits another component of the binary star.

Could The Bethlehem's star be an eruption of Sirius B or Van Maanen's star?

Could The Bethlehem's star be an eruption of Sirius B or Van Maanen's star?

The answer to the question of Bethlehem's star could be an eruption of the surface of Van Maanen's star or Sirius B. 

Could Van Maanen's (1) star (Van Maanen 2) or Sirius B (2)the Bethlehem's star? Van Maanen's star is too cold for being that star, but could that thing be the Sirius B. The age of Sirius B is about 228 million years, but there is the possibility that some kind of eruption on the surface of Sirius B has caused the effect, what we are known as Bethlehem's star. 

The star itself can be old, but sometimes the white dwarfs and neutron stars are impacting with bigger particles or a large mass of gas or dust will be dropped to the surface of the star, and that causes a very big explosion. So this kind of eruption that happens at close star would cause an effect that the new star has been born to skies. 

The most common explanation for that thing is the supernova or nova (3) eruption or explosion, which exploded somewhere in our Galaxy. And that thing is one of the most interesting theories in the world. Some scientists have believed, that the Bethlehem's star is the Van Maanen's star, what is at the distance of the 14,5 light-years from Earth, and that thing would explain the mystery of the Bethlehem's star. 

Van Maanen's star has ever been the supernova, but the nova-eruption, what has been happened so close would be very bright, and that thing would be seen in the darkest night. The key question in this theory is that the age of that white dwarf is too old being Bethlehem's star. But sometimes even the lonely white dwarfs are erupting, when the bigger particles are impacting them, and could the Bethlehem's star be the eruption on the surface of Van Maanen's star?

But the problem is that Van Maanen's star or Van Maanen 2 is too hot being the Bethlehem's star. And that means there could be another white dwarf near Earth, but nobody has been found. Sometimes also Sirius B is claimed to be that nova. 

The distance to that star is 8,611 light-years, which means that also smaller changes to the brightness of that star are easy to recognize. And the surface temperature of Sirius B is very hot, but the reason for that is the material from Sirius A is dropping to Sirius B, and that determines the age of that star difficult by using the surface temperature. But this is only theory. And the answer for the mythical Bethlehem's star could be the eruption on the surface of Sirius B. 

Could the Bethlehem's star be some kind of propaganda tale?

One explanation for the Bethlehem's star would be that it is only the propaganda tale. In that theory, some leaders of the Jewish community or Romans created this tale for making the chosen one brave. The story would be told that God was protecting that child, who will be the king of Jews. 

The purpose of those tales, what are told to noble children's purpose was to prove, that the God or higher spirits were protecting that person, that the royal mission was to complete. And if Jesus was the descendant of the King of Israel, that meant that the royal mission was to get Romans out from that place. 

When we are thinking about the hypothetical descendant of Jesus, we must remember, that the rule of the kings was, that they must protect their families for making the heir for themselves. That means that the holy bloodline would have existed. But this thing is only theory, and the book Da Vinci-code has been made it well-known.
