Casting a $20 Million Mirror for the World’s Largest Telescope
ฝัง

- Building a mirror for any giant telescope is no simple feat. The sheer size of the glass, the nanometer precision of its curves, its carefully calculated optics, and the adaptive software required to run it make this a task of herculean proportions. But the recent castings of the 15-metric ton, off-axis mirrors for the Giant Magellan Telescope forced engineers to push the design and manufacturing process beyond all previous limits.

Imagine on completion someone accidentally drops a wrench on it.
Thay reminded me of a masterpiece called angel wings that was made out of glass. I think it took the artist like 2 years to finish it, then a bunch of kids came and touched the wings even though they were not supposed to and their parents were just standing there taking their photos. The angel winga got broken and the final moments are shown in the museum and it is in a glass cage now
Or being told by a native population you can't use "their" moutain to place it on. Rip all that work

This is the first time I can see something cool on youtube and excitedly yell "I'VE BEEN THERE!". The Richard Carris Mirrorlab is absolutely amazing and worth seeing if anyone is going anywhere near Tucson. When I was there in 2018 they had 3 of the mirrors in various stages. 8.5m is stupidly massive.
I used to live in Tucson and did not know that this existed 😮😮😮
@Rodman Schlemiel I had to look it up to see if the name had been changed. The Richard F Caris mirror lab is under the football stadium but is part of the Steward observatory. Looking at the UA link I checked it might also be called the Stweard Observatory mirror lab because the end of the link is soml (www.as.arizona.edu/soml).
It is an amazing tour. My wife works there and we are so grateful that she was hired to work at the Steward Observatory. #GoWildcats
Excuse me? Did he say "cool it for a _few months_ " ?
Well you wouldn't want it to crack would you...
Yup. The problem with glass (and the reason we have it as well) is that when it cools down, this happens so fast it freezes in a chaotic state ("fast" meaning in the normal course of exposing it to ambient temperature). This will freeze the glass but also freezes all the stresses. Annealing it very very slowly will ensure a release of the stresses while it cools as it remains liquid for far longer and it can settle much better.
It makes total sense. I have experien ed glass shattering from rapid temp change and even metal becomes brittle enough to crack and break when cooled rapidly. It was just a bit of a shock, at the time, when I heard it.
Yep
if not cooled slowly enough, the outside will harden while the inside continues to contract as it cools, and the stress has nowhere to go.....
at first i was damn 20 million for a big miror, those guys getting ripped off, 2 mins later im like, damn, the miror manufacturer should have charge more

Your talkin about 20 million dollars for ONE mirror theres going to be 7 put into the telescope, thats 140 million dollars over the next 4 years, not to mention all the tech that goes into it. The rotating axis for a building standing 22 storys high, in the middle of the desert, and all the computers needed to operate that beast. Your talking about a almost half a billion dollar project.

a mirror of that size... precise to the nanometer level? truly, fcking amazing.
@Al Bundy as smooth a wrinkled paperbags
Truly amazing stuff. As a child, I listened to stories about my grandfather grinding lenses on a cut off section of a telephone pole in his back yard. He ended up constructing a telescope that used a 16-inch diameter paraboloid mirror as its primary optic. At the time (1949), it was one of the largest amateur built telescopes in the state of Ohio. To my knowledge, it still resides in Newton Falls Ohio at the Mahoning Valley Cortese Observatory.
That final animated view of the telescope at 2:14 is just breathtakingly beautiful
Incomprehensible. He said nanometer precision, that to my mind is stunning.
Yep, quite remarkable, they use not only a very accurately ground glass but also an active system that moves and bends the mirror once installed in the telescope, that's the reason for the laser beams shooting out.
Yep, a billionth of a metre variation across 7 metres of parabolic curvature.. impressive..
The head flying over a hard disk is in the same realm of precision, but on a smaller scale.
And to think its still not enough to remove all the distortion from really really far away
for comparison, the wirings of CPUs could go at least 7nm wide. this shows that its precision was on a higher level
Wow. The dedication and precision engineering required to produce this instrument is a credit to mankind.

imagine you sneeze all over it and they have to spend another 2 years polishing and cleaning it haha..
Every time I see this, I am blown away by how long it takes to polish... and then I think about the people responsible for transporting the telescope from U of A to Chile. Too much pressure. I would have a constant and prolonged panic attack over that trip.
Every bump
I would say its already broken, considering the bad luck we have had this year
no it reflected everything off of it
no shit

I would not be surprised if the news came that this was broken. With everything happening this year, I actually expect it.

The earliest telescopes were crude, yes. However, our method of advancement didnt change too much.
Want a better telescope? Make a bigger lense.
Not necessarily, size isn't the only factor that determine how good a telescope is, there's also the design of the telescope, the shape of a telescope's mirror, the type of materials used in the making of a telescope, the polishing of the mirror, ect.
Not entirely true. A 200m mirror wouldn't be any better than a 5m one without adaptive optics. The technology for that is fascinating.
That's not true at all. It's just one of many factors, but it's still relevant as the laws of physics have yet to drastically change
Or. You know. Put it in fucking space.

I.must.steal.that.telescope.
Imagine if this telescope was outside of Earth's athmosphere.
It has the same quality as a telescope out of Earth's atmosphere, BECAUSE it has build in 'adaptive optics'... adaptive optics can compensate the atmospheric disturbations...and this needs a lot of computation-power (which we now have). Back in the 80s/90's the Hubble-Space-Telescope really had an advantage against earth-bounded telescopes, because back then, it wasnt possible, to make adaptive optics. Nowadays its possible, and its not to necessary to build space-telescopes... Space-telescopes nowadays have other advantages... for example pictures at different wavelengths (infrared), to see through dust-clouds and for faintest galaxies which arent to bright at visible wavelenghts, but at infrareds.
arr see ship: In fact, cgi is also possible in astrophotography, but that is called by a different name (= image stakking, or lucky imaging (i can explain you later)).
With adaptive optics (thats the more expensive way) they try to compensate the szintillation of the atmosphere. The atmosphere has partly different refraction then other parts of the atmosphere (you know it because of: flickering of the road on hot summer days (thats also kind of szintillation of atmosphere (in this case near-floor-level)). There are also this kind of flickerings and wobbelings in the upper atmosphere (just like a kind of ocean... thats why the stars with telescopes also flickering and wobbeling.. even the moon surface through telescope... because in every case the telescope must look through the thick turbulent atmosphere).
Adaptive optics try to trick the atmosphere: they send a beam of (usually sodium-laser as far i know) through the atmospere - this laser scatters in the same way in the atmosphere, like the light from the stars... so they analyse this scattering in a fraction of a second, and distort the telescope optics (thousand times a second) TO those scatterings (so there is a full compensation, of the atmospheric turbulences). Result is: a clear image as shot 'without atmosphere' ...even if the image was taken on earth.
THATS adaptive optics mean (you can imagine how expensive this technology is... its not an old technology).
An other way to solve the turbulences of the atmosphere is really kind of cgi (now i come to the explaination of image-stacking). Its the cheap way, and many hobby-astronomers make it that way :
Mathematically speaking: a lot of turbulences smooth eachother out with time... for example: if on a spot of the image through atmosphere the atmosphere distortet : +0,02 % ... but one second later, it distortet -0,02 % ... Then +0,02 % distortion, and -0,02% results in 0% distortion, if a computer calculate the picture with two different atmospheric distortions on that spot (thats the easiest possible way, to explain image stakking (in truth its a little bit more complicated ) ).
Such image is truly "remastered" by a computer ...because the original image would be to hazey, blurry, etc... A lot of hobby-astronomer-sides in the internet show their result with image stakking (or also called: lucky imaging). You can look it up in google.
Its a cheaper way, to eliminate atmospheric turbulences from a astronomy-image... but it has his downsides... thats why the big companies behind big telescopes usually favors the adaptive optics. In comparison with image-stakking its much less 'computer-generated' or better say: computer-remastered.
Hope this helped.. If you have a little bit of money, you also can buy a telescope, and enhance the image quality (also on landscape/nature views) with software-side : image stacking. And if you like the results you also can try the same methode for astronomic pictures taken by your telescope .. you will see, you get much better image-results from the moon , star-clusters , space-nebulas, etc.
Many images compiled together using a computer, deletes the distortion.

Well they seem to be a bit behind schedule, he said mirrors would start being installed by 2023, it's now nearly November of 2023 and they still don't have the mount built or the enclosure!!! However Mirror 7 is now in progress!! They're supposed to do 1 more Mirror as a backup!!
and then one bird poops on it and all is lost =(
not really, alot of efford of the maintenance goes into cleaning and renewing the coating. From time to time the mirror-coating gets completly renewed.
Those lasers can probably fry the birds.
I don’t think birds would be an issue at that altitude. :P
Guess you are just kidding.
In case anyone would like to know, big mirrors are much more resilient against contamination than we commonly think. Google "McDonald gun shooting incident".
Parker Shaw I guess you guessed correctly about him kidding. The glass is resilient, the coating I imagine is not. If its anything similar to “regular” hobby telescopes, it will scratch easily and require a very specialized cleaning procedure, not just your regular lens cleaner cloth. But birds are an unlikely problem I agree. One can only hope to ever see such a telescope in person.
Well that ended rather abruptly..
Because someone dropped it and said ooooh shiiiiizzz!! Lol😟😅😂🤣

Damn 20 million dollars, that's a steal
Not so expensive compared to what it'll achieve.
You forget it has 7 of those 20$ million mirrors... that 140$ Million just for the mirrors.
What, what will it achieve?
tubedude54 Though it’s just a movie’s budget these days, one less movie made compared to scientific advancement, pretty decent already.
Not knocking it at all chen... rather see our money going to things like this than bombs and missiles.
911gp It won’t achieve anything.
when he said... "We start to look at the stars for the first time" was EPIC :D
I need this to generate electricity for my time machine project :D
Its amazing how much money is spent to get a better picture of places we will never see or be.
The amount of *time* this thing takes to make, geez.
how much money would it take to have it done by sunday?
very cool idea. i`m courious what the pictures will look like and what it will teach us.
"Whatch now, the Universe in HD."
Bigger aperture size is able to capture more light and focus it. This means very faint light sources would all of the sudden become brighter. Even without magnification it would be able to see objects not visible to naked eye. More to the point, it's big enough that colors start becoming visible again, not just shades of gray.
This mirror exist.

Oof

>Finally operational
>a random bird shits on it
Absolutely amazing. The technology involved is incredible.
2022: hey guys, so we can achieve this with our cell phone cameras now...
here's a redesign, where we can effectively triple it, should be done by 2030!
2029: ooh, bad news guys...
jojolikescocoa hmm ik what you mean. Apoph...
mondayfool you can't let the poor man joke now can you
@mondayfool Yeah next time maybe they should build a temporary mirror factory at the telescope site and essentially make a giant mirror in situ. Probably build the foundation of the telescope, put a temporary roof on that, get all the mirror manufacturing equipment there and design it so they can do the polishing phase underneath without flipping the mirror, then build a physical protection sheath over the mirror so it can't get damaged and then proceed to build the rest of the telescope. Or maybe use the temporary roof as the protection if that's possible. The limiting factor seems to be the mirror size and it's lack of transportability the bigger it is, so building it in it's final resting place sounds like the answer to me.
This mirror really reflects its production cost...
I'm glad I'm not the one who's in charge of the transport of that mirror
