100-inch Telescope Public Ticket Night (September 10, 2021) - Canceled for Forest Closure

Mount Wilson's 100-inch Telescope Public Ticket Nights make the remarkable experience of telescope viewing available to visitors not associated with a large group. Come up and observe through the largest telescope in the world available to the public, the historic telescope that astronomer Edwin Hubble used to prove the existence of other galaxies and that our Universe is expanding.

• This special viewing session is limited to 16 observers, so there will be plenty of time for everyone to look at a significant number of targets.
• This event allows up to 4 tickets to be purchased by one individual.  Tickets may not be sold or otherwise transferred to another person except by gift. 
• This special session runs from 7:00 p.m. to 1:00 a.m.
• For more viewing session details, please visit our website at:  Mount Wilson Public Ticket Nights

Come enjoy an incredible night of astronomy on the telescope that forever changed our understanding of the scale and nature of our Universe and launched a revolution in astronomy that continues through today!
