Thank you for directly and succinctly addressing the mystery posed in the title with the first 3 minutes. With all the click-bait tactics used by space related channels, this honest and direct approach respects the viewers’ intelligences more than we are used to.
It's always a fine line to get people to check out the videos. As long as we remain focused on the science, it's all for the best.
@@frasercain just so you know. I appreciate your non clickbait format as well.
Yeah I love that!
@@frasercain This is because _you_ don't need to resort to "bait and switch" to get people to watch your videos. 👍
CZcamsrs who do that know their actual content is not as interesting as necessary to pull in enough viewers, as the poster wants. 😒
enneh, if creators did tht all the time i might actually watch the whole video lol
I was camping with a friend in 1970 or so, we both were stargazing … we both saw the same star disappear together. I’m 66 years old now and I’m still convinced that happened.
With the disappearing stars, I'm guessing radioactive contamination because that was the first thing that came into my mind when I heard the date the plates were taken. Not an unheard of phenomenon from photographic equipment of any kind during that period. Chemical engineers at Kodak figured out atomic bombs were being tested before it was even public knowledge because of contamination on film.
He said all that!🤷♂️
@@rodnee2340 He asked what people thought and from my perspective that's the most likely explanation. I'm not about to make something else up that wasn't in the video just to satisfy your desire for novelty.
@@tjzambonischwartz you are projecting! My desire of science is whatever the science says. But if there is no definitive evidence then the point is moot. Stars disappear all the time without explanation. It's probably aliens building as Dyson sphere or a bird pooping on the telescope. Who knows! 😘
Yes but boy the shape/exposure of that contamination sure looks like 3 stars... right size for rest of the stars in the frame.
@@Zukiwi1 it's three point sources of exposure on a monochromatic plate. Point sources are the operative word there. Particulate matter causing radiation exposure on a monochromatic plate against a dark background would look exactly the same as stars.
I'm afraid "but it really LOOKS LIKE THAT" just isn't a good enough argument in this case. In science you have to check your observational biases at the door.
Been loving how bright Jupiter has been. It's been gorgeous, especially last night with that bright moon. About 3 am I got up and looked out the window and it was shining brighter than most of the stars. Pretty incredible.
Just before bed it's bright in the East, and then early morning when I get up it's bright in the West, joined by Saturn and Venus.
Jupiter is always brighter than all of the stars.
Last night it was completely overcast here. Couldn't see any stars at all, but Jupiter was so bright it actually managed to shine through the clouds 😮
Thank you for dealing with the caption first instead of making it clickbait that makes you wait till the end.
You do a great job of coming up with (or getting people to ask) great topics.
I find all of the moons of Jupiter and Saturn fascinating. (behind Mars, which I want to see bootprints on)
Yeap ,that doesn't happen very often, if ever.
I think deciding which missions to approve must be like being a kid in a candy store wanting to buy everything, and then mom says pick 3. I think that is why I often feel disappointed some mission was rejected, but end up excited about every mission.
BTW, thanks for the Halloween creep out. The NASA pictures are cute, you focused my attention on why I'm always vaguely terrified and thrilled and try not to think too long about it.
Hah, remember, the Universe is trying to kill you.
@@frasercain - Its not the universe that is trying to kill me or any man... its our ex's. LOL Far more dangerous.
A kid in a candy store with your mother saying you can only pick three?
How about if your mother gave you only, like, a dollar in change.
Not a nice whole dollar, aka an across the board block grant, but only in change of nickels, dimes and pennies.
Then said "buy whatever you can with this."
But the next time you visited, your mom gave you a dime less than before.
Or, while you were trying to pay, she took another nickel away from you. 😞
.... Except this analogy fails in that once you buy a piece of candy, it is yours and you have it.
In the Space Program, you need to continually fund a project once you have gotten it started.
Just building and launching Voyager I and II was the hardest part, BUT every year since then, that control center has needed staff people who need to be paid.
And, specialists on translating the numeric data that comes back into those lovely pictures, and tech people to work on the probes to keep them running.
Remember, Every year, they need to get the funding they _forecast_ they will need for the next year renewed.
If some kind of complicated problem comes up during that time, and they don't have the right experts or equipment to repair it,
Someone has to be laid off!
And yet, NASA has to also ask for _even more_ money to start _New_ projects.
☹️
The people who grant that money are going to tell them "I was elected by people who want me to _cut_ their taxes! And, I just found out that the greatest federal expense is entitlement payouts, and I *Cannot* cut those!
And, you want me to give you _more money_ for a project that will continue to drain funds out of the Federal Governments pockets, over the next several years? 😡
First time I've ever watched your channel, I'm obsessed with all things space. It's hard to find good channels on CZcams that cover space news and info accurately and thought yours was just another one when I saw the title. But I saw it was being recommended because I watch Dr Becky so I gave it a chance, and you have a new subscriber 👍
Glad you enjoy it! Yeah, it's hard to find good information with all the science spam videos.
I thoroughly enjoy the long form interviews you do.
You do a fantastic job covering all the bases and your not boring great for the field of interest
Thanks a bunch for all the news, Fraser! 😊
Stay safe there with your family! 🖖😊
Thanks as always.
Morning Light Mountain at it again!
OMG noooo, just finished Pandoras Star and getting into Judas Unchained, PFH is the man with the plan when it comes to ‘alien’ aliens!
I love your content Fraser, even if it's way above my understanding at times, I enjoy it. Keep up the great work!
Oh great, I'm glad you're enjoying it. I try to strike the right technical balance. Hopefully you'll get to a point where you've learned enough background info that it all makes sense.
Theres actually four stars missing. One is missing on the upper right in the group of 4. Strange
Your channel is my go-to source for all things science-related. I appreciate the effort you put into creating informative and engaging content for your viewers.
He is your pastor?
Can I just take a moment to send love and respect to whoever does your video editing? Always super high quality, great b roll and photo inlays, and just enough low key video humor to complement the content. In particular, the s-l-o-w fade to gray with the rainy window during Fraser's thoughts about an infinite universe was on point. Kudos, kudos, kudos.
Today I found myself wanting to see the original 1952 plate image at about 2:31 "and you got this image, that then wasn't in the second image". Didn't have to wait too long though, they showed at again at 2:44.
Anton's the best. :-)
yes thanks for getting to the point straight away. Note there's another object that shifted in the 2 o'clock position of the same image (2:45)
Thanks for listing chapters so we can jump to what we are most curious about. Kudos to you for the content and presentation.
Perhaps a high mass fast moving rogue black hole (or other similar object) moving tangentially lensed a background star in the first picture.
Or perhaps, if I understand you correctly, perhaps they moved enough, or the lensing object moved to occlude the stars?
Those three stars which have gone missing do look like gravitational lensing, maybe caused by a wondering blackhole, the light source could be quite dim and wouldn't be visible without the lensing
G'day Fraser, thanks for the great work 👍 love from Australia!
Thanks a lot!
If any of y'all have a chance to catch one of Fraser's interviews, it is totally worth it! He is a great interviewer!
Just want to say how much I am enjoying your videos since discovering you and subscribing. You're very watchable, not least because you look like Richard Dreyfuss (which is obviously one of the greatest honours that can be bestowed upon a person), but also because you present these incredible things in such a friendly way where your unlimited enthusiasm jumps off the screen. It's a tremendous service you're providing, thank you. And speaking of close encounters, I'd love your take on the WOW! signal.
I thought he looked more like the guy that owns that pawnstars show with chumlee. (rick harrison)
A somewhat fanciful explanation for the stars could be occlusion by a darker and closer object.
Thought of that too, but then the object must have stayed in place, blocking these stars untill present day, because they still cannot find the stars.
Howdy Fraiser! Always looking forward to when you post!
I was in a deep sleep taking a nap listening to your words. I was awakened all of a sudden when I thought about the power of the Sun how far away we are and yet we feel it. What is sobering thought the power of the sun.
Question: Regarding the supposed singularities inside of black holes, could it be possible that black holes are not "collapsed" but are forever "collapsing"? With all the gravity crushing all of that space and more importantly time, could it form more of an asymptotic relationship? The crushing would further and further slow the time down so that a singularity is simply impossible to form in the same way anything with mass cannot reach the speed of light but only asymptotically approach it
The models we have to describe how the Universe functions fail near a singularity. That's literally what "singularity" means, a place where math doesn't work. Like how 1/(x-4) doesn't work at x=4. They don't fail at the event horizon, but the various models diverge the closer you get. One model says the collapse takes infinite time, another says crossing the event horizon takes infinite time, another says neither is the case. Our models are incomplete and can't accurately describe what happens there.
A very interesting question . . .
@@StarkRG A very interesting answer to a very interesting question . . .
Indeed. Eric Lerner at LPPFusion maintains that a black hole is an impossibility, and for many reasons.
I have come to question their existence despite having an awful lot of history with them. A painful process indeed.
And I have also come to accept that mathematics *can* be used to describe reality, but it can also be used to describe sheer fantasy, and mathematics does not distinguish between the two.
@@Chris.Davies Very well put. I've often wondered how much of science is based on the math working out but isn't a true description of reality.
I'd love to see a rover sent to Io! Imagine on the ground video capture of a flowing sulpher river...that would be so mind blowing. With regard to planetary debris around a white dwarf, I wonder how difficult it would be to identify technosignatures in the debris.
Oh yeah, I'm sure it would have a very short lifespan. :-)
First image is through the red filter and the second through the blue one. Perhaps the object with large red shift and lens effect could explain it. There are more disappearing small objects visible
Fraser getting into the "shock and awe" thumbnail game. Love it!
Question: what sorts of planetary systems are likely to form around the stars near the galactic centre, if any, in what seems to be a gravitational fairground ride? Are there likely to be a lot of rogue, or at least very confused, planets circulating there too? Not a great place for life, at least on planetary surfaces, I'd imagine. Thanks for another great video.
Not a great place, for life as we know it.
But if life- or something which we now may not even recognize as life, evolved anywhere else in the universe, the chances of it evolving on a planet without atmosphere, and shielding from radiation are existent. It then would be quit possible, that lifeform may well be resistant to radiation. Or maybe even needs it to stay alive. 🎇
My understanding is that the heat and radiation in the center of the Galaxy are ridiculously high. And so biological life is practically precluded.
The more massive stars -- spectral types O and B dwarfs -- theoretically can have planets. These stars form quickly -- 20k years for some so there's little chance for life as we know it to form. Type A dwarfs like Sirius have only 2B years on the main sequence. Even the hotter type F stars are unsuitable.
It's important to keep theories simple. What we are seeing is light bright enough to see, suddenly becoming not bright enough to see. There are many possible explanations for this.
Great episode. Love the interviews too! And ... your editor was hilarious on the scary space segment. 😂😂
Ive seen hundreds of videos and shows about space and yours are probably my favorite.
Looking carefully at the two images with the "lost stars", there are two observations to be made. First, the "three lost stars" are by no means the only stars that are different between the images - there is also a quite obvious difference close to the right border of the images, around a third down from the top. So, not only these three stars are "affected". Second, the image showing the lost stars states RED in the upper right corner, while the other one states BLUE. This usually indicates that the images were taken through different filters. Back in the day this was often done to collect spectral properties (and/or to later create a composite color image). If an object emits only or mainly red light, it would only show up on the image taken through the red filter, and not in the one with the blue filter. This easily explains the difference between the images, with no space for mystery. The only mysterious thing that remains is why the experts did not address this easiest-of-all explanation...
I was just going to comment that. Those are some obvious observations not mentioned in this "mystery" and that's very confusing.
I thought the same, but why can't we find them today?? I'm pretty sure that wouldn't have been overlooked.
@@MichaelLawler yep.. feels like Fraser condensed a lot of information and probably some relevant details got dropped when sharing the news
@@MichaelLawler Being a scientist myself (although not in astrophysics), I looked a little bit into the matter, and indeed the images of the POSS-1 survey were taken in two different spectral regions, "red" and "blue". A relevant publication (Reid et al, 1991. The Second Palomar Sky Survey, PASP 103:661-667) says this about the earlier POSS I project: "Eastman Kodak type-103a emulsions were used for both red and blue plates of the POSS I, with the blue plates being unfiltered 103a-O and the red plates combining 103a-E emulsion with a red plexiglass 2444 filter. The resultant spectral response functions (see MA63) give effective wavelengths of ~ 4100 À in the blue (with a passband of ~ 1100Ă) and ~ 6500 A in the red (passband ~ 500 A).". So, the "blue" image shows objects emitting light between around 355nm and 465nm, the "red" images show objects emitting between 625 and 675nm. Having this out of the way, the questions that remain are (1) why does no one of the science communicators get this straight, but talk about a "mystery" of stars disappearing within minutes in 1952, and (2) what does the POSS II images of the regions look like, or other new images of these fields in difference spectral regions? As to (1), it is important to point out that these stars did NOT "disappear within minutes", but they were not recorded on the "blue" plate because the did not emit blue light. Or in other words, had the "red" and "blue" plates been taken in reverse order, would the people be puzzled about the "mystery" of stars "appearing within minutes"???
Every time I watch your videos I play Son of Nyx in the background, and it really brings everything together with these beautiful visuals. Thank you for your videos!
Brilliant video. Not once was a crazy theory put forward in this video, every piece of information was excellently chosen, it’s the first time I’ve watched a video on space and not gone off the handle because of a ridiculous theory. Bravo! And very well done to the team. AAA+++ presentation and narration from the host. Subscribed!
Im a star gazer and i always see these 3 stars in a triangle and one of them exploded last week which i witnessed at 5am. No bs it was on my bucket list and seeing it explode reminded me of fireworks but you can see the gas emitting from the explosion. What a mesmerizing moment for me!
If you saw a supernova you might want to tell the magazine nova
One idea that has not been talked about but might deserve a mention is that stars disappear from old star maps because we live in a simulation. I know its kinda weird or wacky but it occurred to me when watching another video on this subject. Thanks.
when jesus gets home from school and starts up the universe on his computer.
Same sort of disappearing act kicked off the action in “Pandora’s Star” by Peter Hamilton. Might be a good thing that we don’t currently have the capability to go investigate.
Ooh, I'll check it out. I've heard of that before but I haven't read it.
Good thing we don’t have wormhole technology like in the book, because there is a reason why the book is named “Pandora’s Star” 😁
Very cool channel. I’m glad I stumbled upon this video. Fascinating.
As someone else commented on another video and may explain the objects missing within a 50 min time frame is red vs blue in the upper right corner. I looked up POSS 1 and they were applying an infrared filter for some photos. As to why the object or objects are still missing it’s difficult to say other than a short duration event.
I liked all of your show. I'm signing up. Cheers Aussie James. 🍻
OMG JWST! So much information - I'm blown away. When I was a kid, the cutting edge was Palomar - I love watching the leap in resolution...as for the vanishing stars, multiple disappearances does suggest a gravitational lensing event. I can't think of any other physical process that can do that. Is there only one image *with* the three stars? If so, a flaw in the plate is a plausible explanation.
Hello Sir, love the diction... as a frenchman , i can understand every word you said.Nice job .Thx you.
Oh great. West Coast Canadian accent.
Jupiter's the living Van Gogh painting that just keeps giving.
Always stunned by the beautiful footage and images of that planet. And to think putting a camera on Juno was an afterthought. 📸🎥😯
there is a Peter F. Hamilton book that involves making stars vanish :) pretty good reads, least I think so. Pandora's Star is the name of the book
As I recall, there was a smaller telescope that was next to the 200-inch telescope that did the sky survey. This telescope was smaller but had a bigger field of vision than the big telescope.
The 3 stars are something else. My hand has been drawing them for years. Im looking for them still
I can't believe the title was not clickbait, and you answer quickly!!!!! Thank you i had all but given up hope i would ever get an answer to the title question
The "picture of Jupiter" must be an artistic rendition incorporating facial features.
Very interesting info. I agree..i love Jovian moons, they are super mysterious and cool
I ALWAYS appreciate your videos
👍👍
Nice video, thanks. Unfortunately youtube tried and failed to serve an advert so i havent been able to watch more than a few mins.
Love that take on the spooky Jupiter image 😅
Imagine if all the stars in the sky just started going dark like that a few at a time until none remained...
Having our new BFR, I am excited to think about all of the future options that it holds.
Disappearing stars? That's a major plot point in the great Pandora's Star/Judas Unchained. A great read. It has the most malevolent alien ever.
I came here to say this and found your comment 10 seconds too late…
Great work!
Absolutely love your series.
How do I sponsor you - and how do I ask you a spacy question?
It is hard to imagine three stars disappearing. Even though they are clumped together in the photo, they must be great distances from each other. Thus, a simple explanation is that an opaque object has somehow come between those stars and our viewing position.
Rouge planet heading straight for us?
I'm guessing Lizzo.
Amazing as usual ❤
Europa was the ONE. Now Ganymede? That's pretty cool.🎉
Cool about Hot Spots joined underground on Juno! As my name is Diane, I keep thinking I should have gotten a degree of the universe! :D I love the night sky.
Beatriz Villarroel did an interview with John Michel Godier on his Event Horizon channel. She has found these mysterious transients in photographic plates that pre date the first satellites in the 1950’s. She has sadly hit resistance in obtaining the original plates…..sound familiar?
Suddenly started thinking of Peter Hamiltons book 'Pandoras Star'....
Are they going to put an orbiter around Triton? That'd be a celestial mechanics feat, given the velocity matching delta-vee at arrival. I'd sure like to see them do it.
There's no concrete plan right now, but there are new ideas floated every couple of years. The Chinese have made this a priority too.
We need to learn more about Io. We need to learn more about moons in general. Moons are often FASCINATING, and even potentially habitable.
I can't wait to see what JWST can show us near the galactic core!
Disappearing stars on old photographic plates sounds like the project of Beatriz Villarroel. Have you interviewed her? JMG had her on Event Horizon earlier talking about the possibility of the missing stars being satellites not launched by us.
I haven't but I saw JMGs interview. Really clever idea, to search for satellites before we could launch them.
@@frasercain Looking closer I saw her name on the article with the three stars. And Geoff Marcy, which apparently led to her being uninvited here and there... she wrote about it: academicrightswatch.se/?p=5374
Oh interesting. That's a really tricky case.
HAHAHAHA! Eye of Sauron! Excellent! The stars are bright like those of Elbereth!
The flamingo simulation is amazing!
Glad Fraser is helping me keep up with what's going on in the universe.
That's my job.
great work
There is something big headed our way, it does not take much thought to realize, that something is blocking our site
There's a surprising number of things moving around in those pictures of the disappearing stars.
Hi Fraser, how light would the sky be at night of we lived near the centre of oir galaxy with around 1000 stars per cubic Lightyear? Would it really matter? Or will there be just a lot of bright stars?
I love looking at the stars and in November 2019 I noticed betelgeuse go very dim. Now I know that it's about ready to go supernova and looked forward to it but when people started reporting it the response was odd to say the least.
Well now I search for people who have their heads in the right place and I will subscribe and see how it pans out ❤❤❤
Fraser, as we are sitting in the centre of the gravity well of our star, would that not affect the incoming light particles as we observe them?
The blue shift as the photons accelerate toward us.
Has a comparison been made with the DASCH and APPLAUSE archives? Also, recommend a story on the current status of the completion of the DASCH project. (It seems to be delayed.)
1:00 Mystery solved: The civilization there graduated to a type two civilization and created a perfect Dyson sphere around their stars.
In the center of the milky way, there is a can of Red Bull and Holly cows gravitating around.
What's up frasier, to answer your question at 21 minutes 26 seconds about the crunched up planets with water forming a disc around a white dwarf, I don't think that's necessary good or bad news for us, I do however think it helps to substantiate a theory about the Fermi paradox, being that there is other life in this universe than us that is potentially on level with, or or well beyond our capabilities, but that type of Life likely exists at different times within the universe. Meaning that there's a potential that some of that crushed up wet material around that white dwarf may have been something very similar to Earth, with beings living on it very similar to us, but billions of years ago before earth, or the star that it rotates around formed.
Just some food for thought,
Good vid👍
that stars apper and disapper make perfect sense in the electric universe model. when powerful ion storms comes and goes they would lid up dim stars periodically. everytime the storms relaxe the stars disappear and everytime the storms are active the star appears. its electrciity in space that make stars appear and disapper. its electrcity in space that makes stars pulsate.
very very interesting mate
Thanks for the great vids and all the info on JWST! There are several objects to the right of the 3 stars that fade also...
Regarding the mistery-stars. I'd check the plates themselves on a micro-level.
If it was a spec of "hot" fallout, it could be still there.
But' it's so obvious thatI'm sure they already did it before spending HST time on it.
Titan and Triton, that's not confusing. I'm glad you said, "Neptune's moon Triton...," because I would most certainly have thought of Saturn's largest moon, Titan.
Yeah, totally different moons. Both fascinating.
On the 17th I saw green on the atmosphere of jupiter with Io on the left and Europa to the right
Some disappear too in the upper right corner, smaller ones, and they match the center image disappearing, at the same time so, a simple error, a reflected light from the dome of the observatory?
150,000 potential cases of vanished stars, according to the "Vanishing and Appearing Sources during a Century of Observations" (VASCO) project.
I’ve used hundreds of those plates and it was not unusual to have false negative and positive artifacts as a result of flaws in the emulsion
The first time I became aware of stars disappearing, it was in a novel by Peter Hamilton which occurred because a barrier was placed over a star that existed many light years away.
❤ caught it on Spotify and wow, there is some funky light manipulation with these I think, heavy gravitational threshold bound lensing …. Like lightning
Lightning as a method where Light moves only to the most accommodating region, in proximity and In operability function “harmony”, resonating within the operable region our telescope light interferes with…. The universe accommodating us to see something metaphorically to organize further and distribute gravitational wave potential resonance within our light pressure reciprocation manifold region or whatever arena is set for theoretics or experimentally
As well as accommodating the operable high frequency light pressure reciprocation products of simple light diffusion from bound to operable light reciprocation potentials
Oh that's cool, the video showed up on Spotify, or the audio?
I've read a sci-fi story where the vacuum decay actually spread at c/2 rather than c, so you could see it as an expanding void.
I always want the moon to dress as a jack-o-lantern for 'all hallows day'
I was looking at the sky a few months ago and saw a star go really bright then it disappeared and I have not seen any star in that location. From the Phoenix area it was a little to the left and a little lower than the stars in Orion's belt.
I'm sure someone has suggested this already but could it be from a solitary black hole in the galaxy lensing a background star/galaxy and the black hole moved enough so the magnified object went out of focus? I believe I've heard such transits would be very fleeting but I'm not sure the magnification would be enough so the unmagnified light source would not be seen by Hubble. Black hole transiting a massive flare/nova/supernova, maybe? Also, were there any photos of that area predating the initial sighting of the 3 stars?
Interesting upload thanks......Just a thought if it was nuclear fallout surley with such a long half-life this should still be there or do I have that wrong.....?
That's the plot of Pandora's Star by Peter F Hamilton where not 3 but 2 stars suddenly disappear!
I’ve seen (what seemed to be) a star blink out earlier this year.. it got bright and then it went out all within 3-5 seconds. It was odd. My best guest: a geocentric satellite with rotating mirrors 🤷🏻
Hello Fraser, I have never understood the concept that a star in its red giant phase loses its outer layers before becoming a white dwarf. Surely the mass of the star has the same huge combined gravity that it has always had, so what is the mechanism that allows it to just lose a huge amount of its mass to space, and what proportion is lost?
Same gravity, but two factors play into it, if I was to venture a guess. One, the radiation pressure of the star increases due to the elements being fused gradually changing. Second, the stars are super puffed up. An Earth-mass black hole will have much stronger gravity than an Earth-mass Earth, because the mass is more concentrated. As with all forces, gravity falls off with distance.
Anything orbiting an "Earth-mass Earth" would follow THE SAME ORBITAL PATH as if it were orbiting an "Earth-mass black hole", or an Earth-mass white dwarf (if such a thing were possible), or an Earth-mass *pile of bricks!* (or FEATHERS - - - it doesn't matter.)
The orbit is the same because *THE GRAVITY* IS THE SAME!!!@@Yutani_Crayven
