Yep, I spent my day lurking in the cavernous underbelly of a bustling Arizona football stadium, watching scientists spin giant blobs of glass like giant, expensive pizzas. Who knew that while college students were worrying about touchdowns, geniuses down in the basement were busy crafting the world’s largest telescope mirrors? Yet tucked directly under the east wing of Arizona Stadium at the University of Arizona sits one of the most consequential manufacturing facilities on the planet. The Giant Magellan Telescope Mirror ProjectAmong all the mirrors produced at the Richard F. Caris Mirror Lab, the ones destined for the Giant Magellan Telescope represent the most ambitious chapter yet. Planning Your Visit To The Mirror Lab TourGetting a spot on a Mirror Lab tour takes a little planning, but the effort is absolutely worth it.
