Three Stars Mysteriously Disappeared // So Much JWST News // Io's Global Magma Ocean 

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. 👍 RU-vidrs 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

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.

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 😮

Thanks as always.

Yeap ,that doesn't happen very often, if ever.

OMG noooo, just finished Pandoras Star and getting into Judas Unchained, PFH is the man with the plan when it comes to ‘alien’ aliens!

Glad you enjoy it! Yeah, it's hard to find good information with all the science spam videos.

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? 😡

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

He is your pastor?

Thanks a lot!

I thought he looked more like the guy that owns that pawnstars show with chumlee. (rick harrison)

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. :-)

Oh yeah, I'm sure it would have a very short lifespan. :-)

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.

Or perhaps, if I understand you correctly, perhaps they moved enough, or the lensing object moved to occlude the stars?

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.

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 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"???

Oh great. West Coast Canadian accent.

That's my job.

when jesus gets home from school and starts up the universe on his computer.

If you saw a supernova you might want to tell the magazine nova

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” 😁

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

I came here to say this and found your comment 10 seconds too late…

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.

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?
