    Cosmic Conversations

    Every Third Tuesday at 7:00 pm


    November Topic: "Hot Stuff - Our Sun"


    Cosmic Conservations at the BPO work much like a book group. Topics are pre-selected by the group and become the basis for the evenings conversation.


    These are non-mathematical discussions designed to “ignite a passion for science through the lens of astronomy."


    We offer a hybrid in person plus Zoom format for this Conversation.  In person is a small group (limited to 15 people) at Battle Point Observatory.  Use the "Register" button on the left to attend in person.  Or, if you prefer to attend virtually, use this Zoom sign-up. 


    Advance registration is required, ages 16+.

    Join us at Battle Point Observatory Saturday, December 13th at 6 pm for another riveting Second Saturday Science Talk! 

    "Seasons on Earth and Other Planets"

    Presenter: Erin Leigh Howard, Rubin scientist & BPAA Education Director

    Winter is coming! December 21st, the winter solstice (and the day after our big fundraiser), marks the start of winter and the shortest day of the year. Once we get past that, our days will be getting brighter…but why? What is the science behind the seasons, and what are seasons like on other planets? Join Erin on a journey through the solar system to discover what causes the seasons on every planet, including our own!

    After the talk, stick around for a planetarium show and, if the weather holds, a Star Party. Whether you're a seasoned stargazer or just beginning to look up, there's something for everyone.  All experience levels welcome.

    Registration required, open to the community and to BPAA Members. 

    Limited to 30 people, sign up now!

    Free Admission, $10 suggested donation but any amount appreciated

    If you can't attend in person, you may register to hear the talk on Zoom: Register here for Zoom
