Why the Mt. Wilson Observatory was worth saving

Joshua Bearman of the LA Weekly re-posted a story about his trip to the famous Mt. Wilson Observatory in Los Angles, which came close to being destroyed by the fire. Many thanks to the firefighters who worked so hard and risked their lives to save it!

With the fire threat to Mt. Wilson seemingly abated, I have taken enough of a deep breath to go back and look at one of my favorite early LA Weekly stories, about an awesome trip I took up to the Mt. Wilson observatory and inside the massive, revolving dome of the 100-inch Hooker telescope, the largest in the world for the first half of the twentieth century. (And still a functioning, important facility.) Did you know that the Hooker's 9,000-pound optic was blown at a bottleworks in France, remains the largest such piece of glass, and was carried up the mountain by donkey in 1915? True! And it was there, as you surely know, that Edwin Hubble discovered that the universe is expanding, and by extension, the Big Bang. But did you also know that a few years earlier, it was also Hubble who first discovered that there are galaxies at all? True! Before 1922, it was believed the Milky Way was the whole kit and kaboodle. Hubble sat up there above Altadena night after night and said "Eureka!" Even Einstein had to rethink things and came up for a visit.

Addendum: Here's The LA Times' Tim Rutten on Mt. Wilson Observatory's place in history. (Thanks, Xeni!)
