Astrophysics Special Interest Group

OCA Astrophysics Special Interest Group hosts an in-person forum for members and guests interested in cosmology, the science of the search for extraterrestrial life, the science and technology of space exploration and many other relevant topics. 

Our meetings are a lively mix of open discussion, member presentations and media produced by the astronomy/astrophysics community.  We also take advantage of opportunities to tour regional science facilities such as Mt. Wilson Observatories and the NASA Goldstone Deep Space Communications Complex near Barstow, CA.

Our meetings are held at the historic Heritage Museum of Orange County,  usually on the third Friday of each month at 7 PM.  A monthly meeting agenda is emailed to members that contains meeting location and directions for free access to the Museum grounds.

All members are welcome - come join us for a stimulating evening or visit to an amazing science facility!
