Watching Stars Die: The Hunt for Supernova Progenitors

Roughly once per second in the observable Universe a star ends its life in a catastrophic explosion called a supernova. Astronomers have long believed that only Nature's most massive stars -- roughly 1 out of every 400 that is born -- will end in this dramatic manner. This theory is finally being directly tested through the careful examination of images of the stars taken before the explosion occurred with the Hubble Space Telescope. Professor Leonard will share the results of these studies with us -- shocking surprises and all!
