One hundred years ago, on Nov. 1, 1917, Edwin Hubble used a 100-inch telescope to prove that the universe not only stretched beyond the Milky Way, but that it is expanding. The mighty Hooker telescope was named after the Los Angeles businessman John D. Hooker, who wanted his name attached to the largest telescope ever built. The telescope held this distinction until 1949 and was later instrumental in the discovery of dark matter and the measurement of stars.
On Nov 4, 2017, the Mount Wilson Institute will commemorate this important moment in history with a public celebration from 2-9 p.m. at the Mount Wilson Observatory in La Cañada-Flintridge. Observatory tours will include that famous 100-inch telescope, with viewings through it offered from 6:30-8:30 p.m. There will be opportunities to look up at the skies through smaller telescopes, and guests can visit the 150-foot Solar Tower, which still monitors activities on the sun’s surface. The observatory also invites visitors to bring their own telescopes to this out-of-this-world event. Check out films and gallery exhibits, including the new Gallery of Photon Technology, and hear talks by noted astrophysicist and author Alex Filippenko and Sam Hale, grandson of the observatory’s founder George Ellery Hale.
Parking will be available in the lower parking area, and a $5 U.S. Forest Service Pass is required to park. Day passes can be purchased at the Cosmic Café from 10 a.m.-5 p.m. Learn more at www.mtwilson.edu.
