So basically a nil-all draw.

According to this article, the supernova might herald the first and only coming:

The article also said there would be no life threatening effects beyond 300 light years. That's good....if the models are right.
It does seem that Betelgeuse is at a very good distance for a supernova: Far enough away to pose no danger, but close enough to make one hell of a show. The fact that it is close to the celestial equator is a bonus, as it will be visible planet-wide (very close to the horizon at the poles, but hardly anybody lives there). Much of what I've read about it indicates that it's probably not going to go supernova in my lifetime, but I kind of hope the astrophysicists are wrong, ant it happens next Tuesday.

The locals there have a name for Betelgeuse. They call it "Krypton".

Report of gravitational wave, possibly from Betelgeuse

Could we have detected the core collapse? I'm not actually sure if our detectors would be able to do that. A supernova might sound big but in the grand scheme of gravity waves I'm not sure it qualifies as big.

https://www.cbc.ca/news/technology/b...wave-1.5433653

Sorry, I don't currently know the exact time of the detection.

ETA: In addition to not being sure if a supernova would be big enough I'm also not sure if it could be asymmetrical enough to be detectable.

And another: https://www.livescience.com/mysterio...nal-burst.html This says this was first detected a week ago. So, not likely that the shock wave is still traversing the interior of the star.

That would be spectacular, but it would suck for Orion.

Betelgeuse is rather unstable, so it's not a very neat spheroid.

In the video above, not to spoil it or anything, but the latest evidence and thinking actually suggests that Betelgeuse has a lot more time left. It was once likely two stars, which merged.

So far this seems to be supported by only one paper which proposes that as one possible explanation.
