Two mirrors 8.6 Meters in diameter

Mt Graham International Observatory

I’m kind of a geek, so this was a full-blown nerdgasm when we got the “behind the scenes “ tour.

Although, I understand there’s an even larger one nearing completion in Chile.

These people can tell if there’s water on planet in a star system in another galaxy.

From the outside, there’s a 4 story building on top of a 3 story building. The upper one houses the telescope. And is capable of rotating 460 degrees.

My day job gets me in some weird places.
