Why is Betelgeuse glowing so brightly and behaving so strangely?

Re: Why is Betelgeuse glowing so brightly and behaving so strangely?
#32When it explodes, Betelgeuse is expected to be brighter than the full moon. Gamma ray bursts appear to follow the axis of rotation of the star, and since that axis does not point directly at Earth (it is off by about 20 degrees), that's not a threat. So it will be exciting, scary and safe - like a rollercoaster that everyone on Earth gets to ride at the same time.
Ah. About that "gamma bursts appear to follow the spin axis" rule - do Earth's astronomers have good data, with a comfortable n, to justify confidence that their little planet can't possibly get toasted by this rather large and unstable stellar neighbor? Asking for a friend.

If it does I hope people will look to the stars more and reflect on their beautiful place in the universe. I can hardly envision a more navel gazing species than humans, and we need more people with telescopes and wide views.
Do any other species even have navels?

Turns out they are wrong, what are you gonna do about it? "Betelgeuse... no... stop..."

#38I'd really love to see major space event like Beetlegeuse blowing up during my insignificant life-span
