I've read that Betelgeuse could go supernova from any point now. Is there any chance it may have already happened and we just haven't seen the results of it yet? How soon would we know?

Well, it could have already gone Supernova but the chances are we still won't see it in our lifetime!

Scientists HAVE said its ready to go supernova, but it could go tomorrow, it could go in thousands of years time, its possible it could have gone already but we wouldn't know about it until about 600 years after it as its around 600-650 lightyears from earth, so it would have had to of supernovaed in the 1400s Smile

Also Eta Carinae should supernova soon too, it mimmicked a supernova explosion but survived, its rare when that happens, and has been observed before, and not long after theyve been observed they finally do supernova, Eta Carinae mimicked it nearly 170 years ago so hopefully soon, 8000 lightyears away and it will be extremely bright to those in the south as its a rare type of star being 100 the mass as the sun.
