  • Women Who Changed the Universe

    • 25 Aug 2026
    • 03 Nov 2026
    • 3 sessions
    • on Zoom

    A Women in STEM Book Club

    Three extraordinary women. Three remarkable lives. Three conversations about curiosity, discovery and changing what's possible.

    Join Battle Point Observatory for a three-part fall book club exploring Marie Curie, Vera Rubin and Mae Jemison through books about their lives, discoveries and journeys in science.

    The series is facilitated by Erin Howard, a research scientist whose own work connects directly to astronomy and the Vera C. Rubin Observatory.

    Meet with us on Zoom for one session or all three:

    August 25 | Marie Curie
    Madame Curie by Eve Curie

    September 22 | Vera Rubin
    Vera Rubin: A Life by Jacqueline and Simon Mitton
    Foreword by Jocelyn Bell Burnell

    NEW DATE: November 3 | Mae Jemison
    Find Where the Wind Goes: Moments From My Life by Mae Jemison

    6:00–7:00 PM | Zoom

    Register once and join any or all three conversations.

    Reading with a young scientist?

    Each month's selection also has an optional Kiddo Companion Book so families can share these extraordinary women's stories with the next generation:

    The Story of Marie Curie — Susan B. Katz
    The Stuff Between the Stars: How Vera Rubin Discovered Most of the Universe — Sandra Nickel
    Mae Jemison: A Kid's Book About Reaching Your Dreams — Mary Nhin

    Curious minds welcome. Come discover the women who changed how we see our world—and our universe.

    Join us at Battle Point Observatory Saturday, December 12th at 6:00 pm for Second Saturday Science Talk! 

    "Seasons on Earth and Other Planets"

    Presenter: Erin Leigh Howard, BPAA Education Director

    Winter is coming! December 21st, the winter solstice 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.


    Tickets $5 (free for BPAA Members), please reserve your spot as space is limited.

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