For those interested in the stars and space exploration, there are three key institutions all geographically close by in the Pasadena area: Jet Propulsion Laboratory (JPL), Caltech, and Mount Wilson Observatory. All three offer opportunities open to the public to experience talks with luminaries in the related fields and demonstrations. These include some very popular events in robotics.
Caltech will have a lecture on the legacy of the soon to be retired Spitzer Space Telescope on Jan 29, 8pm-9:30 pm
