Every weekend, the observatories and science museums in the San Francisco Bay Area open up for public viewing, such as the Chabot Space and Science Center and Foothill College Observatory.
Lecture: In the San Francisco area, I always encourage people to visit the monthly meetings of my astronomy club, the San Francisco Amateur Astronomers (SFAA). Every month we have some of the best astronomy speakers present their latest ideas, and this month is no exception, with a science history talk presented by John Dillon entitle "Galileo Reconsidered" on Wednesday July 18th. Click here for more details.
Lecture & Star Party: Once a month at the top of Mt. Tamalpais in Marin County, high above the thick fog of a San Francisco summer's night, you can find a wonderful Saturday night event featuring a lecture in the Mountain Theater, and stargazing with the SFAA afterwards. This Saturday, July 21st, features Dr. David J. Des Marais from the NASA-Ames Research Center. The tile of his talk is “Astrobiology Investigates Life in the Context of Space.” Click here for more details.
I hope you can join us for an upcoming event.
