2016 Mount Wilson Observatory Public Ticket Nights - We have concluded all Public Ticket Night sessions for 2016, and wish to thank all the attendees. This has been a very beneficial program for individuals, as well as generation of funds to keep Mount Wilson Observatory relevant. Please note that private viewing by groups at both the 60 inch and 100 inch telescopes continues until the end of the year. See the links in the left column for information on booking either of these amazing telescopes.

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.
