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.
