Looming over San Francisco since 1973, Sutro Tower's antennae transmit and receive radio and television signals to the nine-county SF Bay Area. Perched above Twin Peaks, the tower has become a local icon, now revered as much as it was abhorred when first built. Visit the tower with us to find out what’s on it, what’s underneath it, and its history, including its transformation from eyesore to icon.

Cities are known to produce a lot of light pollution, making it a challenge for astronomy enthusiasts to view the heavens within city limits. For us in the SF Bay Area, these issues apply, however, exciting results can still be attained between sky gazing and learning about how we all fit into this big thing we call "space". Urban Astronomer Paul Salazar, The Exploratorium's very own Adam Esposito and more demonstrate how to deal with the parameters and the unforgettable experiences that await with simple to no equipment, the right conditions, and some decent timing.
