Betelgeuse will vanish soon

In the vast universe, a star is going to end its life, perhaps.

Betelgeuse is a magnitude 1 star located in the constellation of Orion. It is the largest star whom we can see with naked eyes. It is one of the more popular stars in the sky I guess.

On the other hand, Betelgeuse is recognized as a very old star. A star dramatically expands when its mortality is coming. Recently, it was observed that Betelgeuse is changing its brightness for some months.

What is happened at Betelgeuse is discussed among astrologists. Some researchers prospect Betelgeuse will explode soon. After that, it will become a black hole. If this expectation is correct, we will be able to see the historic phenomenon that a star is dying.

However, others are against this idea. It is so difficult to recognize the status of the space far away from the earth.

Anyway, what we see now is the figure of 700 years ago since Betelgeuse is distant from earth by 700 light year. The fate of Betelgeuse has been already determined. It looks strange.
