Anyone else watch and rewatch these vids countless times? Also, I have a correction for you Nick. If you promise not to take the video down and redo it (like you did the last time I corrected you, I still feel terrible about that...) then I'll tell you what the mistake is (assuming I'm correct of course).
ParallaxNick Hmm.. One man's catastrophic error is another's minor slip up. Rather than second guess your stringent estimation, I've weighed the misleadingness against the risk of taking a wrecking ball to your work... and came away risk adverse. Rapidly changing subject... Very interesting your approach to pronunciation btw. I have an interest in linguistics and I always go with the "native making very little effort" approach, even in a foreign language when that's actually quite an effort from my perspective. For example, if I'm speaking Italian, Tottenham will have three syllables and "Hague" will have a gloteral H in Spanish etc. I'm not criticising your approach in the slightest here, in fact I quite like it. I view language as comunication first - and well, frankly, I like to blend in and not make a fuss. I just remember you bending over backwards to get the pronunciation of Huygens right when I was thinking is have got it wrong on purpose.
@@davidmurphy563 To be fair, the last time I reuploaded wasn't solely at your recommendation; there were several errors in that video that needed fixing. As far as pronciation goes, I was anticipating a number of pissy comments about the "right" way to pronounce Betelgeuse, so I decided to circumvent it.
@@parallaxnick637 Firstly, as for pronunciation and pissiness, there might be the odd wanderer with a chip on his or her shoulder (this being the internet and all) but by and large your audience is better than that. Give us some credit! Second, I give up. You state definitively that Betelguese won't turn into a black hole and will definitely go supernova. In fact, it's outcome is decently uncertain and a black hole is very much on the cards. This is to do with a host of factors which would take a very lengthy comment. Available on request (with sources of course). Also, even if I'm right, I'd say a correction in the description / a pinned comment is perfectly adequate.
I don't even have it in me to write a verbose prose fellating your artistic talents and deft linguistics, but I get that magic of a crisp sunrise creeping above the cluttered horizon beaming down that energy, and as you feel it cascade into a warm glow upon your face, and one can realize that the future is bright because you have a half hour of parallaxnick ahead of you.
I find it strange to hear someone could not find the big cart ( as we call it, if we not say 'big bear'). It is my childhood constellation. I remember clear how much I longed as a toddler to be able to recognize more constellations, but always could only see the big cart. My Mother showed me Orion (and so my more, since she was 'and home' under the stars), but though oh most popular SciFi-TV show was named 'Orion', I never found the constellation. Maybe it has something to do it our direction; at night the room looked into the east, and outside it was south west. But I remember clear the big cart on the heaven. I grew up in Berlin with its huge light pollution, and the big cat was never dim to me, but wonderful and clear.
your channel is damn near perfect i love it yours is my favorite of this type right up there with covert cabals perfect unbiased millitary commentary and mark feltons history reviews of the ww2 and the cold war possitivly addicting
22:35 And we geographers/geologists don’t tell time the way others do either, as shown on that very nifty animation of the alpine ice caps. Nice visual! ⭐️ And also what a wonderful educational video on what a red supergiant actually is. I’m sure most thought, as I did, that it was just like our star but bigger and redder. Not at all! Wow! A boggling, billowing bubble of boiling gasses! Whenever you think you knew everything about a star or a planet, Nick is there to show you a LOT more. Thanks again! ☮️❤️⭐️
My god! This is extremely sentimental and am feeling the deep, poignant unsettling emotions of loss while looking at this marvel of a star. Beautiful presentation as always! Thank you!
I love how you ended the video, saying that you will mourn its death. I can absolutely relate. When I was a kid I would look at it and say to myself that I will live as long as it will. Very nice video. Keep them coming!
Thanks Nick, this is yet another amazing video! On the topic of pronunciation; my name is Michael, a name well known across the western world. Being from Denmark, I grew up with my name pronounced closer to "meekahl". The last 20+ years I've been living in The Netherlands, and working in international environments. Needless to say that my name is never pronounced the way my parents did. I've come to understand that whichever way it is pronounced by people, that is just my name in their language. I once explained the "proper"pronunciation to a couple of colleagues; they now call me "Mike" instead, which in Denmark is considered a completely different name, rather than a nickname. Not sure I am in favor of that, but I have learned to respond to whatever people say when using my name :) During the last 20 years, I've done a fair amount of teaching in IT related topics. Being from a small country, it was natural to learn multiple languages in school, and after moving to another country, I became familiar with a few more. So, when teaching about algorithms etc, named after people, I tried to look up their country of origin, and pronounce their names accordingly. This turned out to be a mistake. For example, Huygens (not IT related, but an example your are familiar with) was Dutch. Now I'd only use the Dutch pronunciation if speaking with a Dutch person, since that is the way they would have heard his name in school. If speaking in English, I'll pronounce it "in the wrong way", because that is how people would like have heard it in school, or in their inner voice when reading the name. I think Betelgeuse should be pronounced the way that is most recognizable to your audience, without worrying too much about how someone in a completely different culture would have pronounced it a thousand years ago. On that note, your pronunciation of "Aldebaran" took me by surprise, because the way I was introduced to the name was via astronomy books when I was very young. You saying it may be the first I've heard it spoken. All that aside, your videos are not only very interesting and educational, they also inspire thought and imagination. Thank you for taking the time to make these!
Aaaah, so good! I've never been very interested in stars themselves, finding myself much more interested in the alien worlds that may inhabit their systems. But you really sold me on the mythology, the constellations, how one can even recognize which star is which. Betelgeuce is indeed amazing ^_^ I've never been in a planetarium yet, funnily enough. I've also never found Orion in the sky. I can fairly consistently find the Big Dipper, though. I was overwhelmed at how big it is the first time I spotted it. Most of the time I just look for planets, but next time I'm out in the night sky, I will know where to look for all these lovely stars
Wow! I just watched this, my first time seeing this channel. I enjoy other astronomy videos, but your presentation is the first one I've seen that is absolutely riveting! Thank you!
The past few times I've thought about not seeing a ParallaxNick video in a while, you upload. I suppose I should think about your videos more often. They always bring a smile to my face. Something about the juxtaposition of science and storytelling I guess, with history and lore thrown in. Keep up the good work.
Just re-watched awaiting new video tonight and really enjoyed this one... I have been watching Betelgeuse a bit more these past few months. Thank you again for your videos!
Dude, I love seeing these videos periodically come up. You could do this full time if you were able to upload more frequently, but I'm sure that would take a lot of the fun kit of it. Love your videos bro, keep it up. Cheers!
Again, what a fascinating, thoroughly researched, creative and literate study of a star I've heard a lot about recently but actually knew almost nothing about. Except the name of course (and you handle that) and the terminal diagnosis, which is, sadly for us, probably still quite distant. Thank you so much for your work. This comes at a stressful time and is gratefully received.
Dude... just found you... that was truely awesome, thanks a bunch, a bushel even. As I travelled, endless questions were popping into my head, and in due course, you answered every one of them !! :) Subscribed....
Man I was having a hard time getting to sleep last night and I was wishing you had a new video I could play on repeat until I dozed off. Well, I am just happy to have it now anyway 😊
Oh happy day!!! Another Parallax Nick video! thank you once again for keeping up the hard work and presenting us these amazing videos. You're relaxing voice with your well-researched and well narrated video always brings a smile to my face thank you so much!
I love your videos, Nick. They remind me of middle school science class, and for the nostalgia, I am grateful. Here's to you and your channel. Can't wait to see you at 100,000 subs (and yes, that WILL happen). Cheers 😁✌
Hey Nick, really looking forward to your upcoming video! I will forever watch them, i love the history and context you provide. All the while it feels like an amazing audio book
22:07 The issue here is not only that Gaia can't handle the brightness of a star like Betelgeuse but the fact that Betelgeuse's angular diameter rivals with its parallax measurement. Even if the full Gaia astrometric accuracy could be used here we would have huge uncertainties due to the fact that the object doesn't appear as a point source. We would have to measure the center of the disk, and that is not an easy task, considering also the fact that it's disk changes shape all the time.
What you say starting at 1:39 seems to imply that the southern hemisphere lacks planetaria, or children that might be taken to them, or something like that. Only those children with a serious interest in astronomy even know what "Big Dipper" means; but I imagine almost all learn about the Southern Cross. Most would recognize Orion, as it's gloriously high in the sky in a summer's evening when skies are clear and it's warm outside.
Yeah, I went back and forth about including the Southern Cross, but I don't know anything about antipodean planetarium programming. So thanks for the input! :)
I seriously don't know why a broadcaster hasn't offered to pay you for this... maybe there would be too much compromise for you? In the mean time.. Thank. You. Mr. Nick. What a treat!
Broadcasters in the United States prefer flogging the same four dead horses over and over again: 1) Black holes, 2) Hellish new planets, 3) String theory/parallel universes and 4) "How a supernova/comet/GRB can destroy America in our lifetime."
@@ernestolombardo5811 True in the UK, too, although we still have 'The Sky at Night'. 'Horizon', which used to be a fairly thorough popular science documentary series, now offers less and less without 'jeopardy' or 'human interest' ...(i.e., the [tiny possibility of] imminent, spectacular destruction of the planet)
This comment has nothing whatever to do with Betelgeuse, or BE-Tal-Guse if you prefer. (I also say Be-tal-juice.) This is just an idea I've had that I think you could run past some real astronomers since you actually know some. I don't. I have long suspected that our solar system had 2 gas giants close to the sun as we have discovered in so many other solar systems. One we will call Vulcan, because that name has already been used for the hypothetical world closer than Mercury. The other is, or was, Mercury. I don't think Mercury is a planet. It's a planetary core. Sometime about 4 billion years ago these two gas giants existed in an orbital resonance, much like Jupiter and Saturn. Vulcan however was in a very weak orbit. That orbit decayed and Vulcan plunged into the sun. Thus explaining where all the lithium in it came from. This collision resulted in a massive solar ejection which, thanks to the orbital resonance, directly struck Mercury. Now Mercury, like any gas giant, would of had a massive magnetic field. But not one strong enough to ward off such a mass ejection at that range. This tore off most of Mercury's atmosphere, leaving it as we see now. The sudden release of all the pressure off of it could help explain Mercury's topography. What it also did was seed a lot of gas into the solar system. I know astronomers love to talk about things in space as if they just drift away. But the law of gravity hasn't been repealed. Some of that gas, even if less than 1% of it, would have been sucked up by the other planets. And for a small planet, like say Venus, it would have amounted to a lot. Quite easily equaling 100x its original atmosphere. And because most of it would have been heavier gases, such as CO2 or sulfur compounds, you can see how devastating that would be to a young planet. Just a thought.
For what it's worth, I've always favored the Orion constellation and there appears to be an interesting chain of coincidences in my life with the constellation. I went to "Orion University." I worked on the P-3 Orion. I used Orion to navigate walking home after a long night at the bar. There's plenty more examples that are interesting to me, but probably not so much to others. I am tattooed as Orion now; each star matching it's reference star's color, relative size, and location.
I love the poetry of your essays. I have always thought that the cold materialism of the natural sciences must be synthesized with the inspiration of the idealism. Humans require meaning as much as food.
"I love Betelgeuse. Siriusly!" Okay, all joking aside, I've chosen to pronounce the name "Beyteljuice" intead of "Beetlejuice", because that's a somewhat more accurate Anglicization of the original Arabic name.
I've got a weird inverse version of your constellation woes, finding the big dipper is incredibly easy for me, but I have honestly never been able to find Orions belt on my own. Even when its been pointed out I can barely tell where it begins and ends! It's such an indistinct form I barely know what to look for! Maybe someday we can both see all the images of our ancestors in full, cheers dude
Thank you SO much for another video! I check almost weekly just to make sure you haven't released anything I've missed! I hope you'll once again set up a patreon at some point so that I can properly sponsor you!
Holy cow, I know I've seen the artwork at 15:58 somewhere. My research lead me to the cover of my favorite book as a child 35 years ago: "National Geographic Picture Atlas of Our Universe" by Roy A. Gallant. Cover Art by John Berkley. Yes, its first publication pre-dates Blade Runner.
(On Betelgeuse when it goes supernova): "...granting us a truly awesome vision of the Universe, and then... be gone." If such a concept might seem difficult to grasp - an unprecedented celestial apparition (to us living in the present era) that is inescapably bright, temporary and utterly alien in nature - may I remind the audience of just such an event: Comet Hale-Bopp in 1997, which was visible for months. Bonus weirdness points for Hale-Bopp being visible both after sunset and before sunrise, a disorienting feature of it's angle of approach - nearly 90º on the nose.
Who has ever seen anyone hunt with a shield and a club? To me Orion has always looked like an archer, bow outstretched, other arm reaching for a fresh arrow.
I almost never comment on youtube but I just wanted you to know that at least a few times a week my partner and I go to bed and say to each other, "I hope Parallax Nick has a new video out tonight". We have even laid there coming up with fantasies how we could get you to make another video haha. In short, you work is amazing and makes so many people happy, keep on keeping on!
I also liked Betelgeuse as a child, though I'm not sure why - probably just because it was in an encyclopedia. Though I'm not from an English speaking country, the star's name in my language is also very cool, kind of epic sounding.
I imagine the death throws of a star take a while before it goes critical. Hopefully it’ll be an obvious resonance that picks up speed at a predictable exponential rate and we’ll all get the show of a lifetime.
Great stuff... one thing ... apparently some other star apparent subtends a greater portion of the sky, but not the sun, nor famous otherwise and escapes fevered mind. It has to do with stars far larger but dimmed by distance more. You see this briefly on scales of star size where B is often included but far from largest. I think B’s Wikipedia article mentions it....
@@parallaxnick637 At the bottom of this section - en.wikipedia.org/wiki/Betelgeuse#Diameter - "Once considered as having the largest angular diameter of any star in the sky after the Sun, Betelgeuse lost that distinction in 1997 when a group of astronomers measured R Doradus with a diameter of 57.0±0.5 mas, although R Doradus, being much closer to Earth at about 200 ly, has a linear diameter roughly one-third that of Betelgeuse."
That point about Pronunciation... I've always sidestepped the issue of saying "Uranus" by using the Greek form, since it is a Greek word. "Ooh-ran-oohs"
Wheres the next part of what makes the new year new ya bam?? Theres only so many times I can fall asleep to yout dulcet tones talking about Proxima (shakes fist like an angry Scottish guy) Only kidding Nick but your channel and Tier Zoo are my fave two channels, get a video posted mate!! Youre like a new Carl Sagan with your dedication to not only the discovery of fascinating facts about the universe but also the history of these discoveries. Honestly your channel is like a new Cosmos to me. Thanks for all your hard work. Hope youre well!
another great video and I too would miss Betelgeuse fades away. I guess our only police will be that we were able to be witness to such a dramatic change in the heavens in our lifetime. But then again it may not go pop for for decades or centuries to come... keep up the great work, very entertaining 👍
26:59 - quite wonky paint job on Betelgeuse, use content-aware fill or clone or patch tool and adjust brightness/contrast on your monitor. /if it was deliberate, I take my words back
Brian Cox throws me off-guard with his pronounciations. While watching one of his "Wonders Of..." programs with my physicist nephew, he abruptly turned to look at me and ask rhetorically "Did he really say ghee-zers?" (instead of guy-zers), then later "Did he say mee-thane?" (instead of meh-thane). Now there's this. You know you're in good company when you're in the company of ParallaxNick.
i remember a zelazney story set around Betelgeuse. Zelazney was my favorite author for a long time, and may still be such. It's going to be strange if that star explodes in my lifetime and looking up to see it nolonger there. So what.. would Orion's shoulder have dislocated in spectacular fashion? And I share your pronounciation of the star. It is how I've most often heard it and pronouncing it any other way feels wierd.
Anyone else watch and rewatch these vids countless times?
Also, I have a correction for you Nick. If you promise not to take the video down and redo it (like you did the last time I corrected you, I still feel terrible about that...) then I'll tell you what the mistake is (assuming I'm correct of course).
I only do that if the mistake is catastrophic enough.
ParallaxNick Hmm.. One man's catastrophic error is another's minor slip up. Rather than second guess your stringent estimation, I've weighed the misleadingness against the risk of taking a wrecking ball to your work... and came away risk adverse.

The factual content is great, but the writing, the narrative description is what makes this series exceptional. Thanks for all of this, I’m hooked.
Your presentations are always so beautifully worded and well put together, I love watching them. Thank you so much!
Love your work, Nick. You have the soul of a poet and the mind of a born teacher.

Mike O'Barr I’m glad I’m not the only one who likes dozing off to his videos
You and Astrum are two of the best astronomy channels on the net.
You know you're a big star when your outermost layers _orbit_ your core.

I pronounce Betelgeuse like beetlejuice, because it's fun to say. If I ever got to name a star, I'd probably call it grubbutter or something.
I like the thought of a child pointing up to say and what star is that. Well that is grubbutter young Billy/Susie .
This comment has nothing whatever to do with Betelgeuse, or BE-Tal-Guse if you prefer. (I also say Be-tal-juice.) This is just an idea I've had that I think you could run past some real astronomers since you actually know some. I don't.
I have long suspected that our solar system had 2 gas giants close to the sun as we have discovered in so many other solar systems. One we will call Vulcan, because that name has already been used for the hypothetical world closer than Mercury. The other is, or was, Mercury. I don't think Mercury is a planet. It's a planetary core.
Sometime about 4 billion years ago these two gas giants existed in an orbital resonance, much like Jupiter and Saturn. Vulcan however was in a very weak orbit. That orbit decayed and Vulcan plunged into the sun. Thus explaining where all the lithium in it came from. This collision resulted in a massive solar ejection which, thanks to the orbital resonance, directly struck Mercury.
Now Mercury, like any gas giant, would of had a massive magnetic field. But not one strong enough to ward off such a mass ejection at that range. This tore off most of Mercury's atmosphere, leaving it as we see now. The sudden release of all the pressure off of it could help explain Mercury's topography.
What it also did was seed a lot of gas into the solar system. I know astronomers love to talk about things in space as if they just drift away. But the law of gravity hasn't been repealed. Some of that gas, even if less than 1% of it, would have been sucked up by the other planets. And for a small planet, like say Venus, it would have amounted to a lot. Quite easily equaling 100x its original atmosphere. And because most of it would have been heavier gases, such as CO2 or sulfur compounds, you can see how devastating that would be to a young planet.
Just a thought.
Excellent video!
In my own cosmology I call Orian,
The Swivel Chair in the Red Light District....
Oh my stars
Thanks for another exceptional video, Nick! Just what I needed this evening
For what it's worth, I've always favored the Orion constellation and there appears to be an interesting chain of coincidences in my life with the constellation.
I went to "Orion University."
I worked on the P-3 Orion.
I used Orion to navigate walking home after a long night at the bar.
There's plenty more examples that are interesting to me, but probably not so much to others.
I am tattooed as Orion now; each star matching it's reference star's color, relative size, and location.
I love the poetry of your essays. I have always thought that the cold materialism of the natural sciences must be synthesized with the inspiration of the idealism. Humans require meaning as much as food.
Love your stuff. An oasis in a desert that life for me is becoming.
Very well done. Especially love all the historical footnotes.
"I love Betelgeuse. Siriusly!"
Okay, all joking aside, I've chosen to pronounce the name "Beyteljuice" intead of "Beetlejuice", because that's a somewhat more accurate Anglicization of the original Arabic name.
I've got a weird inverse version of your constellation woes, finding the big dipper is incredibly easy for me, but I have honestly never been able to find Orions belt on my own. Even when its been pointed out I can barely tell where it begins and ends! It's such an indistinct form I barely know what to look for!
Maybe someday we can both see all the images of our ancestors in full, cheers dude
If you have clear skies, try looking near the horizon at 9:30ish tonight.
You’re an amazing poet and scholar. I tip my hat to you.
I love you I love you I love you. When I see that thumb nail i know I'm in for a treat from my very fav youtuber
How awesome... a new ParallaxNick video✨on a "Sun"day 🌞
I 'c' what you did there!
Get it? c = the speed of light in a vacuum!!
I'll see myself out.
That's what I call a deep dive. Art and science. WELL DONE!
New ParallaxNick video?
I click like then watch and after it goes in my playlist.
Every single time lol
Thank you Nick!
Thank you SO much for another video! I check almost weekly just to make sure you haven't released anything I've missed! I hope you'll once again set up a patreon at some point so that I can properly sponsor you!
Thanks! That was great. No other channel on TH-cam where a new video prompts me to pop a pot of popcorn and set up theater conditions to watch.
New sub here! Can't wait to get into all of these uploads :)
My fav content!
Good to see you back. And with greatly improved sound/editing.
Holy cow, I know I've seen the artwork at 15:58 somewhere. My research lead me to the cover of my favorite book as a child 35 years ago: "National Geographic Picture Atlas of Our Universe" by Roy A. Gallant. Cover Art by John Berkley. Yes, its first publication pre-dates Blade Runner.
Beautifully done Mr Parallax... Bravo.
Welcome back Señor Nick x and what a hot subject right now!!
(On Betelgeuse when it goes supernova): "...granting us a truly awesome vision of the Universe, and then... be gone."
If such a concept might seem difficult to grasp - an unprecedented celestial apparition (to us living in the present era) that is inescapably bright, temporary and utterly alien in nature - may I remind the audience of just such an event: Comet Hale-Bopp in 1997, which was visible for months.
Bonus weirdness points for Hale-Bopp being visible both after sunset and before sunrise, a disorienting feature of it's angle of approach - nearly 90º on the nose.
Who has ever seen anyone hunt with a shield and a club? To me Orion has always looked like an archer, bow outstretched, other arm reaching for a fresh arrow.
I'm with you. The scientist part of me would relish the data we'd get, but I'd be positively heartbroken to see it go.
I almost never comment on youtube but I just wanted you to know that at least a few times a week my partner and I go to bed and say to each other, "I hope Parallax Nick has a new video out tonight". We have even laid there coming up with fantasies how we could get you to make another video haha. In short, you work is amazing and makes so many people happy, keep on keeping on!
Wow. I'm very flattered. I will try to be more prolific in future :)
I'm glad I'm not the only one who will miss Betelgeuse.
The Feels.
Think high of the stars or not, Betelguese is a companion to us all.
I also liked Betelgeuse as a child, though I'm not sure why - probably just because it was in an encyclopedia. Though I'm not from an English speaking country, the star's name in my language is also very cool, kind of epic sounding.
I imagine the death throws of a star take a while before it goes critical. Hopefully it’ll be an obvious resonance that picks up speed at a predictable exponential rate and we’ll all get the show of a lifetime.
Studies after I made this video have suggested we're not due a show for a million years or so I'm afraid...
Great stuff... one thing ... apparently some other star apparent subtends a greater portion of the sky, but not the sun, nor famous otherwise and escapes fevered mind. It has to do with stars far larger but dimmed by distance more. You see this briefly on scales of star size where B is often included but far from largest. I think B’s Wikipedia article mentions it....
Hm. Be interested to know which one.
@@parallaxnick637 At the bottom of this section - en.wikipedia.org/wiki/Betelgeuse#Diameter - "Once considered as having the largest angular diameter of any star in the sky after the Sun, Betelgeuse lost that distinction in 1997 when a group of astronomers measured R Doradus with a diameter of 57.0±0.5 mas, although R Doradus, being much closer to Earth at about 200 ly, has a linear diameter roughly one-third that of Betelgeuse."
And i see it is smaller than B but closer…
@@smkolins I stand corrected :)
Science and artistic prose in one video.
Fulfilling.
@ 14.00 I don't mind what anyone chooses to pronounce the star. My personal preference is Betell Jew
That point about Pronunciation... I've always sidestepped the issue of saying "Uranus" by using the Greek form, since it is a Greek word. "Ooh-ran-oohs"
I'll be dealing with that in my next video :) (the one after the one I'm making now)
Wheres the next part of what makes the new year new ya bam?? Theres only so many times I can fall asleep to yout dulcet tones talking about Proxima (shakes fist like an angry Scottish guy) Only kidding Nick but your channel and Tier Zoo are my fave two channels, get a video posted mate!!
Youre like a new Carl Sagan with your dedication to not only the discovery of fascinating facts about the universe but also the history of these discoveries. Honestly your channel is like a new Cosmos to me. Thanks for all your hard work. Hope youre well!
I intended it to be a continuous three parter, but then no one watched it. So I thought I'd do the next bits every new year.
I still call it Betalgeez. Welcome back Nick!
The Big Dipper comprises the stars that compose it, not the other way around.
eh true enough
It's my favorite star too Nick!!! You will not mourn alone my friend!!!
For years, pre-internet, I thought this star was pronounced Ba tell' gue say.
I wonder if I'm alone in thinking of Orion as the Jewel of the winters sky.
another great video and I too would miss Betelgeuse fades away. I guess our only police will be that we were able to be witness to such a dramatic change in the heavens in our lifetime.
But then again it may not go pop for for decades or centuries to come...
keep up the great work, very entertaining 👍
26:59 - quite wonky paint job on Betelgeuse, use content-aware fill or clone or patch tool and adjust brightness/contrast on your monitor.
/if it was deliberate, I take my words back
"... taken one away" OR, created something else in its place. How can we guess at things such as this that humanity has assuredly not witnessed.
Only things I've seen in just one particular planetarium are movies and laser shows... I must have done something wrong.
There is a fictional movie poster in Grand Theft Auto 5 for “The Shoulder of Orion II” and it had a semi transparent giant red star in the pics.
Strongest and most elegant voice on YT.... 🏋️♂️🎩
Brian Cox throws me off-guard with his pronounciations. While watching one of his "Wonders Of..." programs with my physicist nephew, he abruptly turned to look at me and ask rhetorically "Did he really say ghee-zers?" (instead of guy-zers), then later "Did he say mee-thane?" (instead of meh-thane).
Now there's this. You know you're in good company when you're in the company of ParallaxNick.
I was wondering why there wasn't any ESA's Gaia data on Betelgeuse; thank you for clarifying this. :)
i remember a zelazney story set around Betelgeuse. Zelazney was my favorite author for a long time, and may still be such. It's going to be strange if that star explodes in my lifetime and looking up to see it nolonger there.
So what.. would Orion's shoulder have dislocated in spectacular fashion?
And I share your pronounciation of the star. It is how I've most often heard it and pronouncing it any other way feels wierd.
