    Please help support the Observatory programs and more:

    • Free field trips for schools, where children visit and experience their first glimpse of the wonders of space and excitement for science
    • Unique experiences that combine the wonders of the night sky with technical and creative exploration. 
    • Star Parties, where someone who has never looked through a telescope before suddenly sees the Universe open up before them.
    • Free science talks, so cost is never a barrier to access education and community experience.

    You strengthen the mission of igniting passion for science and learning through the lens of astronomy! 

    With your support, we create opportunities for lifelong learning.

    Cosmic Conversations

    Third Tuesdays at 7:00 pm

    March Topic: The Life Cycles of Stars


    Join in a friendly small group discussion! Cosmic Conversations work much like a book group. Topics are pre-selected by the group, and are a starting point for the conversation.


    Stars are born in a collapsing nebula of dust and gas. Gravity ignites nuclear fusion, causing the star to shine. Eventually the fuel is exhausted and the star reaches the end of its life. Depending on its mass, its demise takes one of several forms: a red dwarf, a white dwarf, a planetary nebula, a red giant, a supernova explosion, a neutron star, or a black hole. Let’s talk about it! Join the Cosmic Conversation as we sort this all out.


    Topic information updates: Resource Links


    These are non-mathematical discussions designed to “ignite a passion for science through the lens of astronomy."  Free and open to the community, ages 16+. All experience levels welcome.


    Register today! This is a hybrid event. Register for the in-person group at Battle Point Observatory with the "Register" button. Or if you prefer to attend virtually, use this Zoom sign-up instead.
