If you visit Tucson the lab is under the stadium. Make reservations for a tour.
Very cool!
how many years bad luck would it be if they broke that mirror?
I hope I live long enough to see the images! They should be spectacular!
Lol, I don’t know... It’s gotta be like eight thousand years!
I hear ya. I’ll be pushing 80 in 2025. Odds aren’t good, but my fingers are crossed!
Poor old Galileo. Fighting a lost cause. His dinky little telescope with poor optics didn’t help either.
I’ll be in my mid 70s then so who knows?
We both need to keep ALL of our appendages crossed! LOL
The science was settled.
Man! How the hell do they polish that?
That’s gonna take a lot of windex to keep clean.
If you are visiting Tucson, a tour of the mirror lab is well worth a trip -

Question to anyone...
Is it possible to build a telescope that uses just light sensitive charge coupled devices instead of mirrors?
Re: How many years bad luck would it be if they broke that mirror?
Since its a telescope, bad luck would be measured in light years.
This GMT is pretty amazing. I often listen to the Universe Today podcast, though it can be a little dry and boring with that Dr. Pamella Gay droning on in that horrible deadpan voice, so I don’t listen as regular as I used to.
I found the “low expansion glass from Japan” company :

They have quite a technical website if you want to dig deeper.
