Unfortunately there is a red flag warning for North Bay (including Mt Tamalpais State Park) starting 8:00pm on Sat Oct 5. Our program scheduled for that evening has been cancelled.  Thank you for your support and participation during 2019 and look forward to bringing astronomy to the Mountain again in 2020.

Illuminating Dark Matter

Dark matter is the cosmic parent of all vast structures in the night sky, including our own Milky Way galaxy. Yet, we know so little about this mysterious stuff that constitutes over 80% of the material universe. This talk will illuminate our universe’s elusive dark matter, highlighting the ingenious methods that scientists use to search for it.
