Information    Application

In the first half of the 20th Century, eminent astronomers such as Harlow Shapley and Edwin Hubble used the incomparable facilities of Mount Wilson Observatory to forever alter humankind's view of our place in a vast and expanding Universe.

Today, Mount Wilson's original solar and night-time telescopes, the world's largest for two generations of astronomers, have been joined by new facilities achieving unprecedented high-resolution views of the stars.
