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

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

@@MrHammerman97 it was more like, you can't use MORE of the mountain, they where already told that the government would remove some of the telescopes to place the new one, it's the natives people land to begin with and even if they didn't anything on the mountain then their shouldn't be....

Wouldn't that be measured in 'light years', or is that how far you'd have to run to avoid the blame.

Imagine the group of foaming at the mouth nerds that turn their attention towards you right after you break said mirror....now imagine those violent bird necks trying to pull you testicles from your body.....now imagine those chicken wire canoes feasting on said testicles.....now imagine those soup-sandwiches vomiting onto your chest the contents of their bellies.....now imagine those violent, autistic, border-line retards forcing you to eat said vomit off of your own chest.....Imagine....

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.....

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.

Gibbet Hoskins and then they'll tell you the earth is flat because the mirrors we use for telescopes are flat.

That's why some people are in charge of 20 million research dollars and those others are living in trailer parks and delusional enough to think they know the truth of the universe. Don't debate flat earthers, they have been irrelevant for over 500 years.

500 years ? Nobody thought the Earth was flat even 1000 years ago.

Nobody though that, every educated person in Europe in last 2300 years know the earth was round.

Cause people are too stupid to understand how smart some people are.

Well, some of them are with the Nobel prize etc. But yeah, not enough are.

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

At least the James Webb telescope will launch a bit sooner... Hopefully

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.

Because someone dropped it and said ooooh shiiiiizzz!! Lol😟😅😂🤣

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.

one finger print on the mirror would be enough to ruin it.

Isn't that what basically happened with Hubble?

hubbles mirror was mis-shapen in the polishing phase due to human error, luckily all it needed was a corrective lens to focus the images, with the james webb telescope slated for launch they better get it right because theres no saving that one, lol

By my calculation it's more like 744738,4 years of bad luck :D Hers my calculation: A normal living room mirror = ~177,8 X ~127 cm this one 25 meter Taking the average of the width and height combined we get ~177,8 + ~127 / 2 = 152,4 cm thats: 2500/152,4 = 16,4 times smaller And would be 7* 16,4 = 114,8 years of bad luck. But well if we also go by the prices Then lets see, her a some prices of random english mirrors: £35.00 + £17.90 + £73.32 + £79.99 + £55.97 + £49.99 + £39.72 + £52.95 + £59.99 + £34.45 + £249.00 = 748,28 Witch gives us and average of 748,28/11 = 68.0254 pound Now translate that to dollar £1 = $1.3807 = $93.948266~$94 And the number or mirrors we can by for the same price as this is: $20.000.000/$94 = 212766 So by that logic its a total of 1489362 years Finaly we could combine the to numbers and get the average: 1489362 + 114,8 / 2 = 744738,4 average years of bad luck. _yeks_ D:

"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.
