We hope you'll join us for the next CAS 2nd Saturday presentation and star gaze. Be sure to invite friends, family and colleagues! The 12 Greatest Astro Events-Ever! It’s a Top Ten list with a few extras tossed in. And you can’t blame us since we have over 13 Billion years of celestial events to choose from. #1 on the list might be the Big Bang that started it all, or the Chixculib asteroid that wiped out the dinosaurs 65 million years ago, Copernicus moving the sun to the center of our solar system, humans walking on the moon or one of NASA’s most recent discoveries. Bring your own Top Twelve list to compare. For our next installment of “CAS 2nd Saturdays”, CAS member, biologist and science educator Jack Berninger presents his twelve astronomical events that changed the history, geology and life on Planet Earth. Jack will share the dynamics of the events and how they influenced our thinking and understanding of the universe and continue to do so today. Every 2nd Saturday the Cincinnati Astronomical Society features area astronomers who bring you the Universe. We invite families, students, teachers and scouts - anyone with a sense of wonder about our solar system, galaxy or the Universe. After Jack’s talk astronomers will be on hand to answer all your spacey questions, you can tour the CAS observatories and learn how telescopes work, and you’ll view Saturn and other night sky treasures through CAS’s four large telescopes. (Presentation held clear or cloudy.) Have a telescope, big or small? Bring it along for expert help exploring the night sky. Astronomy is an exciting and engaging way to teach the STEM (Science, Technology, Engineering and Mathematics) subjects by introducing all the sub-disciplines in astronomy such as astrobiology along with physics, math, chemistry and geology. We never know which young visitor at one of our CAS 2nd Saturdays is going to have a career in the sciences. Some day she might even be turning over rocks on Mars looking for life. Saturday May 11th Program begins at 8pm. Stargazing follows (weather permitting) Admission: Donation Requested Open to all ages! No reservations required.
