September’s Science Topic – Celestial Navigation Through the Ages
13 Sep 2025 19:00 – 21:00
Speaker: Frank Petrie, BPAA President
Did you like last month’s talk on Measuring the Night Sky and want to know more about the ancient navigators that crossed oceans using mental maps of the stars? Or, perhaps you missed last month and also want to see a free showing of a young girl’s journey through history in The Navigators (which we purchased thanks to our donors last year)? Well, either way, we have a treat for you! Our very own Frank Petrie, BPAA President, will be telling us all about celestial navigation, from ancient seafaring peoples to modern day applications.
After the talk, stick around for a planetarium show and, if the weather holds, a Star Party.
(PSST…we are still looking for members to join our Speakers Bureau! Whether you want to give a scheduled talk, or offer to be a stand-in when our scheduled speaker needs to cancel, we need you!)
