100-inch Telescope Public Ticket Night (July 27)

Mount Wilson's 100-inch Telescope Public Ticket Nights make this remarkable experience accessible 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 and runs from 6:30 p.m. to 1:00 a.m.
