I'm forever amazed at the engineering know how that goes into first designing and then building these things. Here's a picture that boggles my mind....This was built by ThyssenKrup that just happened to be the parent corporation of a company I used to work for.
That Halderon Collider thing boggles me too........

I wonder if they use Windex to clean the mirrors.......

wow all the money spent on a telescope, Just think of all the poor black children that money could have helped

I highly recommend reading The Perfect Machine by Ronald Florence. It tells the story of how the Mt Palomar telescope was built. Great read!

Saw a bucket wheel excavator when I was in Fort McMurray AB.
An impressive piece of machinery.

What does that machine do?

I met a imaging specialist working on cameras for it. Very interesting. I understood little of what he was saying but enough to be impressed.
I’m really interested in the James Webb. Taking way to long. It should go up this fall.

Will the view be filled with Musk’s (and probably Bezos’) satellites streaking by?

Just breathe on them, a quick wipe with a bandana, and they’re good to go. Windex and paper towels only needed for dried-on stuff.

No way. Any bird near one of the mirrors is to be shot with a BB gun.

In addition to having viewing power 10 times greater than that of Hubble, the GMT will also have four times the power of the highly-anticipated James Webb Space Telescope, scheduled to launch on October 31st, 2021.Big advances in optics technology in the last couple of decades have made giant ground-based telescopes feasible again. The GMT will be built at a fraction of the cost for getting the Webb telescope up and running and have 4 times the resolving power.
Hats off to the folks doing this project (U.S. led consortium). Still an area where there's real science going on.

My understanding is that, because the Webb’s orbit will be extraordinarily far from earth, it cannot be repaired once launched; so they’re prudently taking extra time to get it right initially. I heard Halloween as the launch-date.

How many years of bad luck if you break one of those mirrors?

“Any bird near one of the mirrors is to be shot with a BB gun.”
No worries. Any bird that flies into a huge mirror complex like this on a sunny day will be in flames in about two seconds from the reflection.

I doubt the astronomers will be looking at stars much on a sunny day, but you never know.
