Indications of Impending Betelgeuse Supernova

To be clear, "impending" in this case means "in decades, not centuries" and "indications" come down to some pretty fascinating modeling of periodicity in its brightness. The theory is that this "pulsation" is the result of intermittent contraction of the core due to running out of a given element to fuse, until higher pressures allow for the fusion of new elements. The belief here is that the star is now nearing the end of its Carbon fusing period, and since it isn't massive enough to fuse Si, its end must be approaching.

This could be true, but it's using some fairly indirect methods to reach that conclusion, so I'd personally wait a few years for more people to get a look at the math and draw firmer conclusions.

Having said all of that, I hope it's true, and I hope that I'm alive to see it.

548 -+49 lightyears away. Means it exploded can. 1500 A.D.?
