When you look up at the sky on a dark night, you’ll notice that the stars appear to twinkle.

At 200 times more powerful than today’s best telescopes...

In this episode of The Atlas Obscura Podcast, we visit a spinning furnace tucked under the football stadium at the University of Arizona, designed to help build giant telescope mirrors.

A behind-the-scenes tour of the University of Arizona’s Richard F. Caris Mirror Laboratory which leads the world in making giant, lightweight mirrors of unprecedented power for a new generation of optical telescopes.

Hubert Martin, Project Scientist at the Mirror Polishing Program, talks with SciFri’s Charles Bergquist about the mirror production process, and the challenges of working with glass on massive scales.
