The last century has seen a revolution in our understanding of the cosmos, including its age — 13.8 billion years — and content: 95% dark matter & dark energy, with only 5% normal matter! To test cosmology theories and to grasp how stars and galaxies formed, UC Berkeley collaborates world-wide to make huge 3D maps of hydrogen, the most abundant cosmic element.
Our speaker, Dr. Josh Dillon, is a Postdoctoral Fellow in the UC Berkeley Astronomy Department.

Mt. Tamalpais State Park closes at sunset; on May 11th, that's ~ 8:10pm. Only vehicles with an Astronomy Program parking pass will be admitted thereafter:
- Print a FREE Astro Program parking pass at this Eventbrite website.
- After sunset, vehicles lacking a parking pass may be cited.
- Vehicles can exit the Park until 10:30pm; after that, remaining vehicles may be cited.
This event is presented, admission-free, by Wonderfest, the Friends of Mount Tam, the San Francisco Amateur Astronomers, and Mt. Tamalpais State Park. Optional sky tour and telescope viewing will follow the lecture.
Bring a flashlight and — even though mountaintop weather (above the fog) can be warmer than down at sea level — wear warm clothes in layers. If rain or wildfire threatens, call 415-455-5370 after 3:30pm on event day to learn about event status.
