Create a life-long memory by observing astronomical objects with the historic Mount Wilson 100-inch Telescope. After seeing first light in 1917, the telescope would be the world's largest until 1949 when the Palomar 200 inch came on line. The world-heritage class Telescope was famously used by Edwin Hubble during the early 1920s to show that the Universe is vast in size compared with the then prevailing view. Hubble followed up this revolutionary discovery by quantifying the expansion of the Universe, thereby launching modern cosmology. Other than Galileo's first instruments, no other telescope has had a similar impact on human understanding of our place in the Universe.

The event includes a tour of the 100-inch telescope dome interior and unequaled observing through the 100-inch telescope from sunset until 1:00 am with a small group of no more than 16 people.
