Silicon Valley Astronomy Lectures
Listen to exciting, non-technical talks on some of the most interesting developments in astronomy and space science. Founded in 1999, the Silicon Valley Astronomy Lectures are presented on six Wednesday evenings during each school year at Foothill College, in the heart of California's Silicon Valley. Speakers include a wide range of noted scientists, explaining astronomical developments in everyday language. The series is organized and moderated by Foothill's astronomy instructor emeritus Andrew Fraknoi and jointly sponsored by the Foothill College Physical Science, Math, and Engineering Division, the SETI Institute, the Astronomical Society of the Pacific, and the University of California Observatories (including the Lick Observatory.)

Dr. Brown (whose discovery of dwarf planet Eris led to the reclassification of Pluto) discusses the history of planetary discovery (and demotion), why we think a new, larger Planet 9 is on the verge of being found, and the techniques that we are using to try to find this very faint body lurking in the far reaches of our planetary system.
