Oxygen: Breathing in Stars
Life as we know it requires oxygen, carbon, and nitrogen. Yet the universe began with none of these elements. The elements responsible for life were produced in the deep recesses of stars over 13 billion years of cosmic time. How these elements assembled to form the dynamic universe that surrounds us and onto the nurturing planet that we live on are some of nature’s greatest mysteries. The world's largest telescopes and the most powerful supercomputer simulations of galaxy formation and evolution show that the elements transform the way new stars are born and evolve, the way planets are formed around young stars, the way stars explode and die, and the way stars assemble into new galaxies. We will take a dramatic journey with oxygen throughout the history of the universe from the Big Bang to the present day. We will follow the birth and death of stars, the formation and evolution of galaxies, and the formation of planets, ending on our own planet earth and the oxygen that we are breathing today.
