Betelgeuse,Betelgeuse,Betelgeuse is acting strange. is it about to explode into massive supernova

642,53 years to be exact.

If I was a betting man, I’d wager that it (Betelgeuse going nova) will be visible here on earth within the next three years.

Oooh drama unfolding.
...well sometime between now and in 20 years. Living on the edge (of my chair)

20 years? Our current understanding says sometime in the next 100,000.

Still plenty of time to get a good seat.

LOL using 20 years as the time frame for me to possibly witness it, Im 58 right now, pretty sure I got at least 20 more good years. Im aware they are infinitely better at earthquake predictions than a celestial event beyond orbital calculations

I have always wondered if it would pop in my lifetime. I know 700 light years is way out there, but supernovae are massive events. Any effect on us at that distance?

Much better article

... supposedly it will be bright enough to be seen during the day, and will hang around long enough for everybody to get a look-see

It's possible it has already

Yep there is that too, but the astrophysicists, don't think so

If Betelgeuse does the champagne supernova I am going to party like its 1323!!

I believe Ligo will know before the visuals hit. I hope that is enough of a warning to point some telescopes at the event! We got lucky with the neutron star merger (dry run anyone? See which people can keep their mouth shut..,) so we’ve known about this for a while!

I suppose it could also be a Dyson Sphere!!

Keep watching the skies!!!

S+F for the final frontier!!

Thanks for the Ligo reminder I stumbled across them the last time I was watching the skies such a cool site got lost in there for hours. I was trying to watch something recently through an Italian observatory online, but it was cloudy the night of the event.

I have been watching this for a while.

There are a many stranger things going on up there.

Luke 21:25
And there shall be signs in the sun, and in the moon, and in the stars; and upon the earth distress of nations, with perplexity; the sea and the waves roaring;

That prophecy of Jesus came to my mind when I read the OP. Remember that everything in it is symbolic. In Bible prophecy the sun and moon and stars represent the ruling elite. The earth represents the stable element of wicked humanity, and the sea and the waves represent the unstable radical elements of humankind. This prophecy is directly fulfilled AFTER the great tribulation. This great tribulation will start with great suddenness and will be heralded in with the unique world-wide cry of "peace and security!" Then in a ferociously sudden act the world's rulers will turn upon false religion and rip her to shreds.

After that event the sign of the son of man will appear in heaven. And that is what Jesus was referring to here in this prophecy. Just because the world's rulers receive one thought for an hour, a thought given to them by Jesus Christ himself, to destroy religion, will not mean they defeated God or there is no God. All humankind will run into atheism and give their allegiance to the state, that is where the mark of the beast, 666 comes in. But too late will they realize that their trust in human organizations is of any saving power. All of the stars of heaven will fall, their scientific elite that preach there is no God and they will be the saviors of humanity. All of the ruling powers of this earth, its sun and moon will simply fade into nothingness, and humankind will see the hopelessness of their situation. For no one will be able to stand against Jesus and his angelic forces on the day of Jehovah's anger.

Now, here is something interesting. There may be literal phenomena in the sky. As Betelgeuse is 700 light years away, that means whatever event happened has already transpired centuries ago by the time its light reaches earth. What if it went supernovae just as all these things transpire? Not saying it will...

a reply to: randomuser

Well, I read your post 4 times looking for fault, and I have to say. I agree with every word.

Edit: except the centuries part.

Sometime between now and 100,000 years....lol I think we need to worry about Yellowstone more. It would have zero effect on Earth other than to be very bright and even seen in the daytime.

a reply to: Xtrozero

If Yellowstone blows, I’ll be living with the groundhogs, one way or another.

I wish there was a way to detect it in advance.

Our light cone disallows any intervening observations.

We could observe a nearby star system for signs of the shock wave from Betelgeuse, someplace inbetween.

Let me get out my star charts...

Here's the thing with Betelgeuse wasn't it fairly stable till 2019, when it had that period of darkening, so even if it doesn't go supernova as long as it's doing different things visually it's interesting AF to me.

You got me interested there TEOT.

I have wondered for some time why we have heavy elements on earth. Someone in a physics lesson said elements heavier than iron were not natural to earth. Couldn't wrap my head around it at the time.

All the gold in the universe

It turns out that the origins of the heaviest elements, such as gold, platinum, uranium—pretty much everything heavier than iron—has been an enduring conundrum. All the lighter elements have well-explained origins in the nuclear fusion reactions that make stars shine or in the explosions of stars (supernovae). Initially, astrophysicists thought supernovae could account for the heavy elements, too, but there have always been problems with that theory, says Enrico Ramirez-Ruiz, professor and chair of astronomy and astrophysics at UC Santa Cruz.

How close is Betelgeuse to the Peleides? Proxima Centauri? I wonder if we've gotten refugee aliens from other solar systems that have been affected by its going Supernova.

a reply to: TEOTWAWKIAIFF

As far as I know, nothing can travel faster than light, not even neutrinos. I agree with what Putnam 6 presented earlier.

The only sure way is to detect the radiation, or other effect at some point in between. I assume the shock wave being discussed is a gravity wave or some sort of particle wave. I don’t think a pressure wave could travel this far.

Am I barking up the wrong tree here? Please correct me if I’m wrong.

I’ve watched that star for many years. Ever since I first heard that it was on the way out as a kid. Orion is one of my favorite constellations because of that. I look at the stars constantly, I am fortunate to live where I can see them.

i thought i watched a you tube vid by the russian dude, antonov or something i'm sure you guys are familiar with him.

i remember him saying lightfoot was closer than we thought
and something was going on too.

just to add, some scientists think novae pushes evolution at a rapid pace.

they were citing the explosions of things like the cambrian explosion of life, etc.

Boy , you sure got that right. I wonder what properties they have that affect evolution? Novae are highly energetic, who knows what their purpose is.

a reply to: Topcraft

If you listen to the skeptic observer, Betelgeuse is the third star to go into a nova from the galactic center, he thinks that Sol is next as the pulse from the galactic center moves out. He thinks that they are mini novas where the dust from the pulse gets blown off the star.Then we get our three days of darkness.

a reply to: Topcraft

If I understand correctly, the nova imparts a gravitational wave first before the light/xray/fireworks. There is a bit of lag time depending upon distance.

I think the kilonova had 1.5 hours between Ligo and Hubble sightings. They even got a few radio telescopes repointed to add to the spectrum they observed.

They probably have contingencies in order to capture data should the right sequence of events happens. And probably an “oh crap!” plan if it is irregular nova event.

Again, that was my quip about the neutron star merger being a rehearsal for a more spectacular event.



ETA: The other part about “what happens” is really an open question. Some say “nothing. Space is too big” and others say “great reset as Earth is pummeled by gamma rays (or favorite doomporn radiation)”. I was worried when I was younger but think that the distance is too big to immediately effect the planet.

But I have been known to be wrong. From time to time. Oh dear…

Spooky action at a distance is faster than light ,,, proven but the physics involved are unknown !

All the best

a reply to: putnam6

Fortunately for us, the nearest star that could go supernova is Spica, 260 light years away, relatively safe distance. Most of the stars close to our sun are low mass stars, too small to explode that way. If Sirius or Vega blew like that, we might be in serious trouble.
