“Construction of the Palomar Observatory (1948)
In 1948, after decades of planning and wartime delays, workers at Palomar Mountain were finalizing one of the most ambitious scientific tools of the century: the 200-inch Hale Telescope. Located in the remote mountains of San Diego County, the observatory was far from city lights, offering crystal-clear night skies. Scientists and builders worked side-by-side, balancing fragile optics with concrete, steel, and innovation. When completed, it would be the world’s largest telescope, peering into galaxies never before seen. For years, Palomar would lead the field of astronomy, revealing the size and structure of the universe. In many ways, it brought the stars a little closer to Earth.”
I’m thinking this comment might be more correct:
From: Curtis Croulet
“The photo was taken in 1938. The 200-inch telescope would not be completed until 1947. It was dedicated and named the Hale Telescope on Jun 3, 1948. It wasn’t ready for science until Nov 13, 1949.”
Another shared about a wonderful book:

“An amazing story about how it was built.”
