Our Origins in Exploding Stars

The elements that make up the earth and ourselves -- the calcium in our bones, the iron in our blood -- were originally fused in the cores of exploding stars. This lecture presents a story of stellar life, death and rebirth -- how an ancient generation of massive stars came to blow themselves apart as supernovae, how we were formed from the clouds of their ashes, and how remnants of the old giants are still around in the form of ultra-dense objects like black holes and neutron stars. Today, high-fidelity supercomputer simulations allow us to understand and visualize what actually goes on deep within the fiery crucible of exploding stars.
