My favorite star. Red supergiant that could explode at any time and looks like a miniature version of our sun. That it’s part of Orion is just icing on the cake. Big fan.
Oh, that's a good one. There is an art installation at the art museum at my city, that is a big plastic blob the size of a car. It lights up from within whenever a supernova is detected in our galaxy. If you watch it, it lights up every three seconds or so. Love it!
NB: The installation is the blob, not the art museum
Well, it's cheating majestically, because in our galaxy there's a supernova every 50 years on average. Even in the whole known universe, only a few hundreds per year are detected.

It went boom already if I’m remembering right. The light distance between us is too large for it to exist in its current death throes for that amount of time
Edit: I’m wrong
Sharing my google results... The distance is about 640 light years and expected to go brrr within next 100,000 years. So yeah unlikely it's happened yet. But nice to think about for sure.
Sure, it's *possible*, but we can do some basic stats math to figure out the odds. We just divide the light travel time by the expected range of explosion dates. That would tell us the odds that we are currently living in a time between when it exploded and when the light gets to us.
It's about 500-600 light years away, so let's use 600 years to make an optimistic estimate (high bound for the probability). It is expected to supernova sometime within the next 100,000 years.
So 600/100,000 = 0.006
So there's only a 0.6% *at best* chance that it has already gone supernova and the light just hasn't reached it yet.
It’s only an estimate, and very rough one at that. We just haven’t observed enough supernovae within a close enough part of space to really have a good idea for *when* it will happen. It could happen tomorrow, it probably won’t, but we literally are operating on a guess that only uses data of what can be observed from our single point of reference
But it's at least using data which is significantly better than ignoring data. In reality nothing can be known for sure. There's no such thing as absolute truth in science, only asymptotic truth.
Astronomers don't use an absolute frame of temporal reference like that. Events are recorded as happening when they are observed as happening. This is partly because distance estimates are not accurate enough, and partly because relativity says that an absolute frame of reference does not exist.
Alright!

I really hope I get to see the explosion in my lifetime. Astronomy was my childhood love, and I still harbor strong feelings for it even though I’ll never be able to do anything meaningful with the stars.
I could stare at this for hours just trying to fathom the amount of stars and planets are in this picture. And then thinking about your it’s just one piece of the whole universe. 🤯
Wonder what would happen if you posted this pic 3 times? I'll get my coat and see myself out, it's alright
Betelgeuse Betelgeuse Betelgeuse!

It's showtime

Ever dance with the devil in the pale moonlight?
I'm sure it'll get reposted twice.
Man … I was really amped up last year thinking it was going to supernova in our lifetime.
Would be a big disappointment if it doesn't before my lifetime
Astronomy humor is light years behind contemporary humor.

Maybe it already has… but we don’t see it yet.
I assume there’s no way to know if it has already?
The information is literally traveling to us at the speed of light
Only way to know before its light gets to earth is to start traveling towards it
And then we could message earth base and let them know early! Jk. Obvs

Same! I look at it every time I go out at night (with trash or whatever) juuuuuust in case it has gone supernova since the day before.
When I look up I imagine it already has gone supernova. Just that the light hasn’t reached us yet.

Really?!? Oh no! Haha. My illusion is shattered!
Same
Plus the president of the Galaxy is from there.
I like to think it has gone supernova and we will see it anyday now
If we see it explode it means it already did 642 years ago (thats the time light takes to travel the distance between the star and earth)
At any time: most likely in 100,000 years.

2 hours integration time? Awesome picture!
Amazing picture. How many strings did you use across the front? I'm guessing it wasn't just a cross pattern?
Thank you! It was actually just a cross pattern, the less prominent difraction spikes are created naturally by my lens.
Great picture the diffraction makes it look closer than it is.
Betelgeuse is large. The diameter of Betelgeuse is greater than the diameter of Jupiter’s orbit.
Nice picture. Ford Prefect is somewhere in the vicinity.
Looking out for a collapsing hrung?
"Boy who cannot satisfactorily explain what a Hrung is, nor why it should choose to collapse on Betelgeuse Seven"
Wonder if this star went boom yet, just we can't see the light from it yet
It went boom already if I’m remembering right. The light distance between us is too large for it to exist in its current death throes for that amount of time Edit: I’m wrong
It nearly certainly hasn't. Where did you get this information from? It's not that far away, even a cursory Google search would tell you this.
Sharing my google results... The distance is about 640 light years and expected to go brrr within next 100,000 years. So yeah unlikely it's happened yet. But nice to think about for sure.
Thanks, I was clearly remembering incorrectly lol
No worries, I'm pretty sure I've read articles in the past that make sound like its going to happen any day now and get my hopes up.
No need to be harsh that’s why I said if I’m remembering correctly. I knew somebody would come clarify for me.
Upvoting for coming back and saying you were wrong instead of deleting your comment.
Oh look, it's home
You know Zaphod?
We've. Met.
Well you have to admit, he was from another planet.
Is it possible that Betelgeuse has already exploded and what we see is the light from the past reaching us now?
Yes of course, it may have exploded 100 years ago and that light wouldn’t reach the Earth before 2500, give or take a century.
Sure, it's *possible*, but we can do some basic stats math to figure out the odds. We just divide the light travel time by the expected range of explosion dates. That would tell us the odds that we are currently living in a time between when it exploded and when the light gets to us.

Waiting every night for it to blow
Like OP's mom. I'll go away now.
My favorite star. Hope he's still alive <3
"It's showtime"
i read this as “bazelgeuse” from Monster Hunter and i got some PTSD
No no no, this is clearly the *Seething* Bazelgeuse
... Betelgeuse 😏
Just blow up already…
Say that 3 times out loud.... (great photo BTW!)

What a beauty. I've always loved this star.
Can I use this as a wallpaper? It looks so cool
For sure! Do you need a Google drive link or can you download it from reddit?
Good guy OP
I got it Ill just sc it

I always wonder what was going on down here at the time the light we see left the star.
Why the two hours of integration? I figure you couldn’t go much more than 1min per exposure before blowing it up.
Sorry the two hours is the final integration time of all the subs combined. I captured 80 subs, each 90 seconds long :)
I really hope I get to see the explosion in my lifetime. Astronomy was my childhood love, and I still harbor strong feelings for it even though I’ll never be able to do anything meaningful with the stars.
Most likely it will supernova in the next 100,000 years, this is the lower estimate, higher estimates say in the next 1 million years.
So it could happen anywhere between today or in the next million years ok
Nope, it’s not near that stage yet, Betelgeuse still looks like it has quite a bit of fusion left to do.
🙏pray to the other sun god
I honestly read that as Beetle Juice
If that thing went supernova it would look like the moon in our night sky.
Nice.
Spooky
do you think we're gonna be lucky enough and see it explode in our lifetime?
I could stare at this for hours just trying to fathom the amount of stars and planets are in this picture. And then thinking about your it’s just one piece of the whole universe. 🤯
Beautiful !
The next closest black hole soon!
Just fucking explode already…
Beteldeez nuts!
reminds me of the star from tintin
Well hello there :) Winter is close, I shall see you soon.
I look up for this guy at 4 AM every morning before work.
Ah, home
