You mean, Did it go Supernova hundreds of years ago, and Will we notice it tomorrow, perhaps?

[angrylittlespider]

Say "supernova, supernova, supernova" and see what happens.

[KarlPhillips-sl]

Betelgeuse is around 700 light-years away, so the explosion took place around 1324 AD. This means that it takes the light from this star about 700 years to reach Earth, however anything with mass and/or charges will take a lot longer to reach us as they can't travel at the speed of light, so we should be okay for a few hundred, thousand or millions of years. If the energy from this event goes out in all directions, the surface area of a sphere is 4πr2 so Earth will only get exposed to a fraction of energy, however due to the sensitivity and lack of protection of a lot of our electrical infrastructure and devices, it could still affect Earth; a bit like the Carrington Event in 1859, but it will not be for a while yet. We can all sleep well in our beds at least tonight people.

They said there was one super nova in 2016 they viewed but because of the way stars bend light another view of the same supernova will be viewed in 2037. That’s crazy fascinating. It’s like seeing someone fall down through binoculars and then 21 years later looking and seeing the same exact thing happening again to the same person like it just happened. Like time travel

[aaronscott]

when a star explodes it has to be within 160ish light years before it will damage our planet. betelgeuse is over 700 light years away and poses no threat to our planet. while the site of a star within 1000 light years will be amazing and beautiful it will NOT hurt earth!!!!

[Dudleymiddleton]

Don't forget we are looking at it about 6-700 light years away, the progress scale/time * of the nebula explosion at the immense scale of around 1000 times the diameter of our sun, a mere 865, 000 miles in diameter is extremely slow - think of the big volcanoes that go off, the smoke stack is almost static to us, and that is only a thin slice of our tiny Earth in comparison, so, like the horses head nebula, it is almost frozen in time. *Also remember the gerry Anderson thunderbirds and captain scarlett water/explosion scenes making the water like syrup.

Witnessing a supernova with my naked eye is on my bucket list. Something akin to the July, 4th A.D. 1054 crab supernova would be awesome.

[KathiOsborn]

It did super nova in the 1700, the light of it is approaching us now and is anticipated to be here in our life time.

[Wesley_H]

I find it funny we’ve been talking about Betelgeuse for years, then suddenly that upstart T Corona Borealis enters the news cycle. I’ve seen one total solar eclipse and several partials in my life. I would love to see a supernova in my lifetime.

[calstach]

Ok hold on here.. first of all there is again no mention of the fact that it takes nearly 700 years for the light from Betelgeuse to reach us so it actually may have gone supernova centuries ago and second.. I thought nothing traveled faster than the speed of light as you say neutrinos do.. so if we are about to witness this phenomenon than perhaps we have already encountered the neutrinos if they do indeed travel faster than light. Colour me confused

[LOBO]

Hope I'm still about when it goes, what a beautiful sight that would be to watch

[ernestfeddersen]

It will outshine everything in the sky except for the Moon.... This magnitude makes it brighter than the moon.... What?

[bradenhenry]

I really hope we can experience this in our lifetime

[vladnurk]

if Betelgeuse blew up today we wouldn't know for 642 yrs

[moiraatkinson]

Awesome! I really hope it happens in my lifetime. I’ve heard it mentioned that they think the star of Nazareth was a bright supernova.

[SadanandPathak-udhj]

If you see an explosion today you can presume that it took 642 years ago.

[RevengeUntamed]

How do the unique characteristics and impacts of different supernovae, such as Betelgeuse's, contribute to our understanding of stellar evolution and the universe's dynamics?

[AnnRkcah]

Said it 3 times he showed up in my bathroom 😂

[jessebacon]

If it did, doesn’t that mean it had already gone supernova years ago and we are just now seeing the light?

[steveday]

I dont think light acts the way we think it does. If we see a star, i dont think its years and years old what we are seeing...i cant fathom that notion im my head. I believe we are seeing it real time. Its just so big that we see it is all.
