It's 642 light years away, so if we saw the immense brightening tomorrow night the actual explosion would have happened in the year 1376 about 28 years after the European Black Plague.

The video was made with Universe Sandbox 2.

I'm confused with the distance thing if it was to blow up right now because of the distance the explosion will not be seen for years ..because the light from the explosion will take years to get here is that right and that would be 642 years ??? so if you look at it with the Hubble telescope could you see it has blown up allready but the light hasn't got here yet from the explosion. is that correct ???

If and when Betelguese goes supernova, we won't know it for another 640 years.

Fake Science, but awesome fantasy. 😎🌃🌆

I thought perhaps you could have talked a little more about the main sequence life; how it ran out of hydrogen, the core collapsed under gravity making a compact hot interior which expanded the surface. There are some great papers describing its wispy ethereal nature - it's not what most people expect from a star. You could have said about red being low flux. Might have been also worth saying that it might have already exploded - oh and there's no danger to life on Earth!! I hope you don't mind the suggestions, I did enjoy the video though.

Truth about the comment section:
I laughed so hard when someone said R.i.p Betelgeuse

[BonnKialStevens]

I have many sources that say it is around 640 ly away.
