Wiki has it at 700 light years but it may be as low as 500 light years away https://en.wikipedia.org/wiki/Betelgeuse This will be the first time we have witnessed a supernova in our backyard (we can see the star at night, its in the Orion constellation) so we dont know if we are in any trouble yet. When it goes then it will shine as bright as the sun in the day. The problem is how much will that raise global temperatures? A mere 30C rise and its over for most life on Earth. Is that why the Pope has to leave Rome during the End of Days? Will it be the true cause of the apocalypse? The Bible says for a short-time all life will end on Earth, is this why?

Tatetopa Posted December 24, 2019 #7 Share Posted December 24, 2019 What a relief. I was afraid if I said Beetlejuice out loud three times, it would explode. On the heavier side, in the meantime we will have to fix the world or screw it up by ourselves 1 1 Link to comment Share on other sites More sharing options...

Skulduggery Posted December 24, 2019 #9 Share Posted December 24, 2019 From what I’ve read in the past it should not affect us much. But, it will be bright. Link to comment Share on other sites More sharing options...
Skulduggery Posted December 24, 2019 #10 Share Posted December 24, 2019 It is a question of when. It could be next year. It could be hundreds of thousands. Who knows? Link to comment Share on other sites More sharing options...

Who knows? Its most likely to be at some point over the next 1000 years, which means it might already have gone supernova but we wont know about it until the light reaches us. 1 Link to comment Share on other sites More sharing options...
Vorg Posted December 24, 2019 #12 Share Posted December 24, 2019 I'm curious what the highest magnification telescope has looked at this star. It might have already exploded if we use a higher powered telescope. Link to comment Share on other sites More sharing options...

The light from the star would still have to reach the telescope so we wouldn't know about it any sooner. 3 1 Link to comment Share on other sites More sharing options...

Duke Wellington Posted December 24, 2019 #15 Share Posted December 24, 2019 4 minutes ago, Skulduggery said: Of course. Betelgeuse has an estimated radius of 1400 times that of the sun assuming it is 600 light years away making it one of the largest stars in the known universe. Thats also why we can see it with the naked eye and its so unstable its no longer round as can be seen in the link https://astronomynow.com/2017/06/30/see-the-sharpest-ever-view-of-giant-betelgeuse/. If its further like 700 or even a 1000 light years then thats a humongous supernova waiting to happen. Maybe a dinosaur extinction level event that is going to decimate the human race? 1 Link to comment Share on other sites More sharing options...

Skulduggery Posted December 25, 2019 #17 Share Posted December 25, 2019 I have been up on the Betelgeuse knowledge since about 2011 or so. Most places I’ve looked on the internet—scientific resources—say we are clear. Although I do suspect there may be a kernel of truth in the sensationalism of it that has been going around for quite some time. There may be some type of effect.

DreadLordAvatar Posted December 25, 2019 #18 Share Posted December 25, 2019 If we do get to see it, then the explosion happened 700 years ago. Link to comment Share on other sites More sharing options...

fred_mc Posted December 27, 2019 #20 Share Posted December 27, 2019 Why are they talking about a Dyson sphere? It would be really stupid aliens if they try to build a Dyson sphere around a dying giant star that is giving off huge deadly flares as a part of the death process. 2 Link to comment Share on other sites More sharing options...

I was expecting a Tatooine situation. I was going to wait until it happens before I pass on. Don't think I'll bother waiting now. 2 Link to comment Share on other sites More sharing options...

To be fair, the article does say that is an extremely unlikely option. Link to comment Share on other sites More sharing options...

+Desertrat56 Posted January 24, 2020 #25 Share Posted January 24, 2020 If it is 500 - 700 light years away it may already have gone supernova. What we see happened 500 - 700 years ago. Link to comment Share on other sites More sharing options...
