Guest speaker Dr. Pogge from Ohio State Astronomy Dept will be speaking about “Chasing Oxygen”!

The Big Bang made only hydrogen and helium plus tiny traces of lithium and deuterium. This is why hydrogen and helium are the primary chemical elements that make up the universe today.  However, here on Earth Oxygen is far and away the most abundant chemical element.  Oxygen makes up about 46% of Earth’s crust, 22% of the air we breathe, and 65% of mass of the human body. Where was all of the Oxygen made? How is it distributed throughout the Galaxy and eventually find its way into planets and people? This talk will explore the origin of the elements heavier than helium in the universe, and describe how astronomers measure and map the distribution of Oxygen in interstellar space.

Richard Pogge is a Professor of Astronomy and Vice Chair for Instrumentation at The Ohio State University. Prof. Pogge received a BS in physics from Caltech and a PhD in Astronomy & Astrophysics from UC Santa Cruz.  After being the W.J. McDonald Postdoctoral Fellow at the University of Texas, he came to Ohio State in 1989 as a postdoctoral researcher. He then joined the faculty in 1992.

General Information on our Meetings and Public Talks:

Our meetings include time for show-and-tell, telescope setup questions, special introductory content for newcomers, socializing time, and in-depth astronomy content for our more experienced members… in short, something for everyone!

Visitors are welcome and encouraged to attend. You do not need to be a CCAS member to attend meetings. Folks are welcome to bring astronomy equipment, books and photos to share with the group. We like to assist in answering questions or help with equipment operation techniques when needed, BUT FIRST, please contact the CCAS to discuss this, as meetings are sometimes already booked solid with topics, or, there may not be anyone at the meeting who is knowledgeable of the item you need help with.

If you have questions about bringing something to a meeting, or wish to ask specific technical questions, or about meetings in general, just let us know.
