... Inside the long battle to maintain the spot where we found our place in the universe

Los Angeles was once the best place in the world to see the universe.

The most important things we know about the cosmos were discovered in the early 20th century at Mt. Wilson Observatory. It was here, 100 years ago, that Edwin Hubble noted a light in the distance that would lead to one of science's greatest discoveries.

By night, astronomers kept watch at the best telescopes on Earth. But by day, a city grew between the mountain and the sea. The lights of Los Angeles multiplied with each passing year until their glow obscured that of the stars above.

Astronomers moved on to clearer skies, beneath which larger and more powerful telescopes would be built. And Mt. Wilson Observatory discovered what so many aging luminaries in L.A. have: Once your star light fades, no one is quite sure what to do with you.
