"What's that?" asked Lou.
"The observatory at Kitt Peak. We'll pass the access road when we head west."
"Let's go there!"
So we did. We feel much smarter.
Kitt Peak has the largest collection of astronomical telescopes (optical and radio) in the world
A solar telescope. Half of its length is underground
Depending on where you measure, the summit is 6,800+ feet
A "smaller" 2.1 meter optical telescope. Yeah science, bitch!
Much smaller telescopes through which I saw sun spots and solar flares in real time
