Mount Wilson Observatory “Talks & Telescopes” w/ Dr. Rosaly M.C. Lopes

Mount Wilson Observatory (MWO)—Southern California’s esteemed home to several of the most groundbreaking astronomical discoveries in history—welcomes the public to the third “Saturday Evening Talks & Telescopes” of the season on Saturday July 12 2025. 

MWO is honored to present a talk by NASA Jet Propulsion Laboratory’s Dr. Rosaly M.C. Lopes Deputy Director for Planetary Science entitled “Volcanism in the Solar System.” The lecture explores volcanoes across the Solar System from Earth to the moons of Jupiter and Saturn highlighting their diverse forms and their impact on planetary landscapes. Tickets are available here: www.mtwilson.edu/events/talk071225

During the six-month season each “Talks & Telescopes” event runs from 5:30pm to 11:45pm with the “talk” portion of the evening beginning in the Observatory’s Auditorium. The 60+ minute presentation is followed by picnic dining—bring your own or purchase* from a food truck or caterer and then after the sun goes down stargazing through Mount Wilson’s immense telescopes the largest in the world made available to the public. Additional stargazing around the grounds will be available thanks to members of the Los Angeles Astronomical Society.

Both the 60-inch telescope and the 100-inch —the latter famously used by Edwin Hubble to discover the expanding universe— will be available for viewing the night sky. Priced at $50 this event series offers the most economical stargazing event option on the mountain. Tickets and more information are available on Mount Wilson Observatory’s website here: www.mtwilson.edu/lectures. Advance purchases are highly recommended.
