[QUOTE="Channel Hopper, post: 612648, member: 175144"] Reading further, it appears that the star is only now exhausting up its hydrogen stock and needs to go many stages further (through the Helium/carbon /heavier elements) before it goes out with a bang. I have no info on the current spectroscopy of Betelgeuse at the moment, but I can presume that the only change we might see for at least a thousand or so years, is a variation in luminosity, and colour change to blue, or white-blue. Since Llew has also brought the time / distance equation into the fold, this might mean that any civilisations that were under threat from the changes might now be buzzing round this solar system, if they left using some light-speed technology. So keep an eye out for any unusual activity (bright lights or a sore arse after seeing bright lights) Any budding astronomers out there with some better ideas ? [/QUOTE]
