Cosmic Cocktail Hour

Presented by: Pasadena Senior Center
85 E. Holly Street
Pasadena, CA 91105


Members $7; Non-members over 50 - $10


When it was founded in 1904, Mount Wilson Observatory was home to the world’s largest telescope. Since then, the observatory’s telescopes have been used by world-famous astronomers, among them the likes of Edwin Hubble and George Ellery Hale, to make countless extraordinary discoveries.

For this month’s Cosmic Cocktail Hour, Tim Thompson, a Mount Wilson Institute trustee, will lead a presentation about Mount Wilson Observatory’s fascinating history Wednesday, April 7, at 4 p.m. via Zoom, sponsored by the Pasadena Senior Center. 

The observatory’s history spans from 1889 when astronomy was first brought to the isolated mountaintop, to 1923 when astronomer Margaret Harwood became the first woman allowed to use the observatory, to 1944 when astronomer Walter Baade took advantage of World War II blackout conditions to observe stars in the center of the Andromeda Galaxy for the first time, to today as Mount Wilson Observatory carries on its storied legacy.

The cost of the Zoom event is only $7 for members of the Pasadena Senior Center and $10 for nonmembers 50 and older. Residency in Pasadena is not required.
