Slightly off topic, but ties into this conversation. My Aunt was a radiologist in Salt Lake in 1950’s and 1960’s. She knew every time there was a secret underground nuclear test because they would get weird spots and hazing on the X-ray negatives. They would send the film back to Kodak for reimbursement, and I learned not to long ago that Kodak was reimbursed by the Federal Government. When my Aunt was telling this, my Grandmother ( who was a cook at the Mt Hale observatory), said that she remembered mentioning how the researchers said that the nuke guys screwed up their photographic plates. One of those small world things!

As I understand that there were no Atomic explosions the year of the plate was exposed. And Kodak started shipping the plates protected with lead after Kodak found out about the radiation. This still would not precluded contamination, just makes it harder to explain.

​@@oldmech619there were no REPORTED atomic tests.

[@janschrder]

Many angles have been mentioned above. One thing, that springs to mind, is that the left plate is marked "Red" (upper right corner) and the other "Blue". If this somehow refers to different spectral ranges, then an explanation could be that the "triple Star" rather were some other objects much closer to us. Objects, that were much more visible in the red spectrum than in the blue. Another thing that is worth observing, is if other objects are now visibel in the area,where the triblet is now missing - indicating that the triblet is really gone. This could indicate if radioactive particles were the culprits. Then again, comparing to earlier recordings, this should be simple to rule out. Now, I've got no education in this field, så this is just what springs to mind.

Maybe the objects were very red shifted. The images that show the object were taken through a red filter (as seen in the image notation). The ones without were exposures taken through a blue filter (also seen in the image notation). Its possible they were very visible in IR light and without the specifications of the filters the image train we do not know if the would show up in the other image. For example if a narrow band filter was used to take one set of exposures and other images were taken to be added for an color image composite it is possible to see where an object that was high in IR content maybe captured and not show up in the blue set of images used to create that composite.

[@gecho8848]

The idea of stars vanishing in distant space and us not noticing for a long time reminds me of playing the game outer wilds. And the terror of realizing after many hours playing that the stars in the background were dying constantly with increasing frequency. Then looking at the local star.

Kodak really did have a problem securing photographic material that wasn't affected by radioactive testing. Fact they were able to discover some radioactive testing that wasn't divulged by the US government because they found some trees produced poor plates because they were too close to radioactive tests

[@ScottHardy-mv4fr]

Maybe I missed something. Have any of these stars been observed by two different telescopes or at two different times? That would eliminate contamination. What about rogue planets or dark stars passing in front of them? And do stars appear as well as disappear?

[@pete_lind]

it's taking photos night after night from same point , it's used to determine if there are moving objects . Easy these days with tracking telescope. Depending of the distances of those stars , you can have interstellar clouds that blocks our view If those stars are 10 000 light years away, it happened long time ago, astronomical time scales are too long for one generation to observe. We need to build giant telescopes on dark side of the moon, that wont totally hinder light pollution from earth, but would be a good start. Canary island has biggest one piece mirror telescope, 10, 5 m/34ft main mirror , we need bigger on moon build from segments like JWST , thats only 6, 5m/21ft

[@oldmech619]

@@pete_lind. You may have been thinking of the telescope we need on the far side of the moon is Lunar Crater Radio Telescope (LCRT). The LCRT would use a 1-kilometer diameter wire mesh to form a parabolic reflector inside a lunar crater. The mesh would be deployed by robots and anchored to the crater wall. The LCRT would be able to observe radio waves at wavelengths from 10 meters to 50 meters. This wavelength range is particularly interesting to astronomers because it contains signals from the early universe, before the first stars and galaxies formed. These frequencies can not be studied from the earth or near earth due to interference. There is a lot to learn.

My thought exactly. The difference between seen exactly once and more than once would make a *huge* difference. I kinda wonder if these types of events are also showing up in data from All Sky Survey projects? A little math says that, assuming these events are not local but "out there" (and by implication, random) there should be on the order of 1 disappearance a month.

[@terryhunt2659]

This may already have been commented on, but I notice that for the 'triple transient' the earlier (by 56 minutes) of the two plates is in the red band, and the other is in the blue (a common technique that allows an approximate colour/temperature measurement). _If_ the triple object were extremely red, the difference between these two specific plates might be explained (though the nature of the object would not). If later, and modern, images of the same location reveal no object, we are left with a very red phenomenon that had vanished entirely by the time of the next oldest image. I wonder if there are useful images of the location from _before_ 1952?

That's pretty normal in astroimmaging, the smaller specks etc are sometimes noise induced (hence shifting paces) or they are actual objects but just disappear because the next image had shorter exposure, etc. But its the main 3 bright stars that matter, that kind of formation of bright stuff is too unlikely to vanish.

Hi, I would like to share my own similar experience. Last month, I was taking 10 minutes long sub exposures during my astrophotography session, and then after downloading them on my computer, I was going through each sub (fits) to check for light streaks and clouds. Strangely, in one of the subs, there was a bright star present, but in the next one, it wasn't there. Surprisingly, it was truly bright one, and there were no other stars that appeared or disappered from the sub before or after that particular sub. For 2-3 days, I kept searching the web if anyone else has noted something similar, but then considering it just as some wierd isolated event, I forgot about it until I came across this video.

A spec is not how nuclear radiation effects these things. It has to be a certain type of film like for X-rays and such that is sensitive to radiation and it would be a whole lot of these "specs" like a hazing. One I dont think that these plates are sensitive to radiation and likely more akin to standard camera film. Two the evidence doesn't correlate with known effects of nuclear testing on the sensitive exposures made by kodak at the time

[@christopherg2347]

[@StarShine-Ranch]

Somebody else in the comments pointed out the "Red" and "Blue" words in the top right corners of both 1952 photos, suggesting these were different filters being used. Since other stars also seem to change in brightness between the 2 photos 1 hour apart, this seems likely. But why haven't any astronomers noticed this?!? Too obvious?!? C'mon!

[@1ifemare]

"The APM POSS1 Northern Sky catalogue contains measurements from both the blue(O) and red(E) plates. The POSS is based on plates taken in two wavebands during the period 1949 to 1955. The blue plates were taken using Eastman 103a-O emulsion, and the red plate were taken with Eastman 103a-E emulsion and hence are commonly known as O and E plates respectively. The blue(O) band pass is primarily defined on the UV side by the transmission characteristics of the glass corrector and the atmosphere, and on the red side by the emulsion. The red(E) bandpass is primarily defined on the blue side by a coloured filter (red Plexiglas 2400 which is similar to Wratten 29). The red side is determined by the emulsion response."

[@colincampbell767]

Colored filters are used in amateur astrophotography to create color images from faint deep space objects. Three images are created each using one of three colored filters (Yellow, Magenta, and Cyan). Each image is then processed so that the white light on the image is changed to the color of the filter used for that Image and then the images are 'stacked' to produce a full color image. This is typically done when imaging brighter galaxies and nebula. (Astrophotography is a very technical and arcane hobby.) Professional astronomers don't do this because they want to capture the full spectrum of what their target so they can gather scientific data.

[@StarShine-Ranch]

@@colincampbell767 - Bear in mind that what professional astronomers did 70 years ago would seem "amateur" today. From Google: "Color photography was not widely used until the 1960s because it was expensive." My father was a professional photographer and got out of the business in 1965 when his clients wanted to switch to color for their newspaper and magazine ads. He didn't want to replace his *black-and-white* with much more expensive *color* photo processing equipment and chemicals.

[@frauleenijssens9353]

Especially in a one hour time frame...if not a contaminate, maybe the Roswell visitors👽 photo bombed the first pic and they were closer than can be determined, which could explain how they could disappear from that area within an hours time.🤪 If it was radioactive dust contaminate wouldn't it be detectable on photo paper or negative given the long half life of isotopes? Although I'm not sure of how these photos were developed. I'm basing my hypothesis on how photos used to be developed from early cameras.

[@rogeratygc7895]

@@frauleenijssens9353 Intensely radioactive isotopes, which would produce effects from a very small quantity of material, will in the nature of things have a short half-life and thus be long gone. Secondly, the film will be most sensitive before development, less so during it, and insensitive after fixing, and will have been washed thoroughly after each chemical bath, so even checking for radioactivity immediately after development would be unlikely to show anything even given an incredibly sensitive detector (like a photographic emulsion!). Of course, a second exposure taken even minutes later, being on a different plate or film, is not going to show the same spots.

Could it be the flip side of gravitational lensing? We’re all used to seeing images or multiples thereof caused by gravitational effects on light.

Can these vanishing stars also be found when comparing plates from e.g the seventies or eighties to images of nowadays? If not, the problem lies in the fifties or in other words - on earth. If yes, it might be a cosmic problem.

[@TheNoiseySpectator]

I don't think he answered the question of if those three stars are there today. Still, if they were there in the plates during the 1950s until that hour if that day, and then were gone the next hour of that day, and did not reappear on any plates in future decades, that _is exactly how_ it would appear if those three stars really did stop shining on that day, during that hour. There are probably many different reasons for any given star to go out, the universe is a big place, and it is doubtful the same phenomenon would have affected all of them. However, in this case, we can be sure that all three in one trinary system didn't disappear from coincidentally different causes.

Perhaps that's the real Trisolaris system, and we can't see it any more because the invasion fleet is so large it's been blocking the view for the last 70 years.

[@Hydde87]

Maybe it's due to some other inconsistency between the way two pictures were taken. If you compare the left picture with the right one, you notice that the left one has a lot more visible stars in general, not just the triplet. The left one also appears to further cropped out and zoomed in which makes me think the pictures were taken with different resolutions or exposures or something. I understand that those 3 stars, being among the more brighter ones in the picture shouldn't disappear like that even if the pictures are different, but the results would for sure be more reliable if both were taken under the same circumstances.

[@sqeeye3102]

Absolutely, that was the first thing that I noticed as well. Every star in the right picture appears less bright than the left picture. I don't know what the difference between POSS1 Red and POSS1 Blue (upper right corner of image) is, but it definitely seems to be the variable causing such a dramatic and obvious difference. There is also another very large and bright star just to the lower left of the triple cluster in the right image that is completely missing as well.

[@jimmaccauley]

The red and blue indicatse what wavelength of light the plates were measuring. The fact that they are differing wavelength plates seems like an obvious problem with the "conclusions".

9:40 this was slightly misinterpreted - in the paper, they test a scenario in which these objects are causally linked (a fair assumption, given that they all went dim within 50 minutes) in order to set a maximum limit on how far these objects are from *one another*. They find that this distance, given (50 minutes * the speed of light), is about 6 astronomical units (6 times the distance from the earth to the sun). Now, given that they are at most 6 au apart, the researchers used their angular separation in the sky to construct a maximum distance to the objects from Earth, which is the ~2 light years that you cited. So in summary, if the objects are causally linked (triggered by something), they can be no more than 6 AU apart from each other and no more than 2 light years away from earth. Of course, they could be much closer.

If anyone knows what that's like, you will know that the view of the stars up there is like nothing you've ever seen. It's magnificent! The stars blanket the sky and you can see it all. Anyway,my girlfriend at the time was with me to observe this also. What looked like the stars in deep space began to move and change positions. We watched dozens of stars doing this. It was breath taking. I am a life long sky watcher and have experienced many amazing sightings in my life. I know what planes,jets,satellites, starlink,spacestion excetra are.

Just a thought, but with the triple stars disappearing, one plate is labelled 'red' and the other 'blue'. If these colours represent filters used with a monochrome camera, then the stars might have been visible in one plate and not the other because of their spectral type. A predominantly blue star could be MUCH brighter when using a blue filter, and very dim, or even invisible when using a red filter ... and vice versa.

Ecept that the area has subsequently been examined and there is nothing there. There was probably noth8ng there to begin with, and the "stars" are just some sort of artefact in the image.

Good idea, but you have it backwards. A blue light would disappear when using a blue filter, but would appear brighter when using a red filter.

[@_cul8r_]

@@Unknown17 There are 5 filter colors that are commonly used in black and white photography - red, orange, yellow, green, and blue. Each lets through its own color of light and blocks other colors to varying degrees. For example, a red filter will let red light through, but block most green and blue. The result is that colors matching the filter color appear brighter in the final image, while other colors appear darker.

[@BGBTech]

A few times I have idly wondered: How can we be sure that things like causality apply the same everywhere? Vs, being a more localized phenomena. Say, for example, if for nearby space pretty much every atom is consistent; but this consistency falls off with distance. Given enough distance, small features could start vary randomly, based mostly on probability. Given enough distance, stars could flicker into and out of existence depending on the probability of a star having existed in that location (from the perspective of the observer), ... Though, I guess, one can always build better telescopes to try to sort this out (say, to verify that the stars always remain the same, or alternately, maybe if far across the universe, possibly even whole galaxies are flickering into and out of existence...).

[@brainretardant]

This is true, the galaxy and universe is not expanding, we are in a gravitational cusp and accelerate towards the cusp. You are standing on one cusp that is collapsing as it is collapsing into another cusp and so on. All of these cusps are shrinking and liberating energy from mass. The outside isn't getting bigger, we are getting smaller.

[@rossholst5315]

Have we attempted to look for some of these missing objects at longer wavelengths? Could the wavelengths have shifted out of the detectable range? Perhaps the wavelengths shifted from visible light to infrared and can no longer be detected in visible spectrum, requiring a different observation platform. Also it seems that high energy particles could also have caused some of these objects. Have we compared the observation dates to that of nuclear test dates?

I once saw a pair of star fading away with my very own eyes. They look like a pair of eyes closing in the distant night starry sky. My hypothesis is that quantum mechanic effects extend all the way to macroscopic objects, astronomical sized objects included. Always would be a small chance that when looking a way from an object, the next time you try to see it, the object would appear somewhere else. Although a simple calculation would lead to an astronomical low probability to such event to occur, here we are seeing an astronomical number of objects and therefore once in a while one of those objects look like has vanished. That also would explain why some people report object switching places in their houses (Well, technically, the explanation in this case would need to be more elaborate, but I hope you got the idea).

[@Nefville]

I kind of like the idea of a singular star that was refracting somehow through a cloud of gas or something we aren't seeing making it look like it was in multiple places; a star which itself was obscured by something. Like an extrasolar sundog that's been blocked by the gas that was originally causing it to refract. Maybe they're the Terminator stars and _they'll be back._ Or its just the most obvious thing and an issue with the equipment or processing.

Wonderful Anton, yes, why do stars disappear from the screen (firmament)? I always try to give symbolic answers when the question seems difficult and there is no such simple solution, so here's an attempt on my part: 1) Stars are like fish and black holes are like fishermen, and sometimes a fish disappears on the fisherman's fishing rod and later in his mouth and stomach. 2) Just like here on our roads, accidents occur in space from time to time; collisions (mergers of stars) and explosions (supernovae) also occur! 3) Stars are living beings, just like us humans. So I think sometimes they get really tired, turn off the lights and go to sleep... 🤣

[@kennoble9581]

I camp on Palomar Mountain (not far from the observatory) and in Anza Borrego State Park which is in the desert just east of Palomar. While camping if looking to the east you will often see planes flying westward. What is important, the planes are not flying across but directly at and descending toward the observatory. Their lights tend to begin faintly and then grow brighter as they approach. They also relatively line up that you will see them stacking up behind each other. Just before they get completely overhead, they either turn north toward LA and Orange county or south toward San Diego. These could be either civilian or military aircraft. I was taken back with this mystery the first time I saw it, but when the planes banked their green and red side lights became visible. If one could obtain the arrival information for planes landing at that time, maybe this could explain the oddity.

[@TheNoiseySpectator]

I don't think so, the section of the sky is much larger than the space between L.A. and San Diego. To move so far that they would be out of view of anywhere covered by that photographic plate, they would have to move Very, VERY *VERY* FAST! Much, MUCH faster than the speed of light! Especially to get away in less than an hour! And, if they were still somewhere in the region covered by the photograph, the Astronomers would still spot them, and realize they were not a "newcomer stars" because they would be the same size and brightness as the missing trio.

[@GenUineUFOs6833]

Max. Your explanation could be closer to the truth than what you think.While taking a video of what I thought was a star on 27.05.19 at 1.20am, I accidentally zoomed into an elongated craft that was pointed at the front and appeared to be artificially illuminated towards the rear built-up area. I enhanced a photo taken from the video that shows what I call a battleship shaped craft. It could also be the reason why stars disappear.They've moved or turned the lights off.

Good catch! The POSS red would be in the infrared range?(invisible to our eyes) but the objects dont show up on POSS blue. So not detected in the optical but identified in the infrared range.. it narrows down what they could be. Need to see same area at a later time to see if they truly "vanished", but perhaps they're still there. That seems like too simple an answer...am I missing something?

[@mitakeet]

@@frauleenijssens9353 I should've looked at the paper before posting. On page 3 they show the same location in red and blue 2 months later and the 'stars' are missing in the red. It still could be something that wasn't visible with the blue filter and could've taken much longer to 'vanish' (as opposed to 50 minutes), but to have three seems to stretch that idea. That said, if you compare the red to blue and look at around the 80,60 pixels for red (bottom first) and 100,140 for the blue, there are clearly objects that 'vanish' between red and blue, so not totally implausible. I noticed that arrangement quickly, might've even subliminally done so watching Anton's video, but a quick scan indicates there may be others.

[@Viaexplore]

At time 8:18 those two pictures are actually showing two different part of the light spectrum. You can see the note on upper right corner saying RED and BLUE. I assume, that it corresponds to a filter used to take the picture. So the 3 stars in the middle and another 3 above are emmiting only red light which of course it is not visible in blue filtered image. That is how it disapears.

As some others have said, an object or dark cloud occluding those specific close-together light sources should have been mentioned as a possibility. It all really depends on what other photographs of that exact area before and after when those two plates were exposed shows. Were the objects there before that? Are they back now? At what wavelengths? The triple 'stars' might be a set of things that are very red-shifted, and so do not appear with a narrow blue filter. Without the critical information as to whether this was wavelength dependent, physical photographic plate dependent, or time dependent, and in what manner, we are all just speculating in the dark.

During the cold war no further nuclear testing was done in New Mexico. The nuclear testing was moved to the Marshall Islands in the South Pacific in 1946. And testing was started in 1951 in Nevada. The Nevada testing site is also much closer to the Mt Palomar observatory. About 400 miles almost due north.
