Betelgeuse: Going Supernova

    I have only come across this information but I thought I would post about it, even if you guys had already heard of this.

    Interesting, but I doubt we will ever witness this in our life time. Unless it has already exploded much time before now.
  2. You are correct in your assessment there Phisix, the star may have exploded a few hundred years ago for all we currently know, in which case we'd miss the explosion. I just seriously hope that the gamma burst is completely absorbed by the Earths atmosphere, otherwise things could go bad... very bad.
  3. It's the wrong kind of star to have any kind of impact on the Earth. GRB's are only produced by the most massive stars which produce a certain type of collapse at the core. As it stands, if we do get to see Betelgeuse go, it'll just be a fantastic light show..
  4. Well according to that article we would have endless or more hours of sun for a few weeks or so. I wonder how much impact that would make to nature and animals? I will be fine as I can sleep in the daylight if needed.
  5. Its pretty common for some people to have 24 hours sun for some weeks in the summers :)
  6. Not in England lol.
  7. I certianly hope so anyway. But I also hope that when it does happen, it occurs during the night, so it will be hugely disorientating for everyone on the planet. That'd be fun.
  8. It's night time everywhere at the same time now?
  9. Good point, I wasn't thinking when I posted that. I hope its night for Australia when it happens.
  10. Funny thing is... the star probably already went supernova hundreds of years ago and the light just hasn't reached us yet.

    Sometimes people forget that looking at the stars is looking way into the past. Stuff that happened across the universe when Jesus was alive, still hasn't reached us yet. For all we know, entire galaxies or even the universe could already be ending from some massive super-duper vacuum black-holish thingy, and we wouldn't know for another thousand years or so.
  11. Well it's not funny, that's the only way it could have happened considering it is 640 light-years away. We were simply discussing when it would be apparent to us, which could be anywhere from a year away to sometime within the next century considering the wavelengths of light and their intensity that we can currently measure from the star.
  12. If 640 million people all at the same time say "Betelgeuse! Betelgeuse! Betelgeuse!" then the supernova will appear. You need a million people per light year, obviously.
