Milky Way's Youngest Supernova Found

Astronomers have identified the yougest known supernova in our galaxy. They estimate the star exploded 140 years ago sending out an enormous amount of energy. That would have caught the eye of some 19th century observer, if the supernova had not been shrouded in so much dust. Before this discovery, the last known supernova took place in 1680. Stephen Reynolds at North Carolina State University was one of the astronomers to identify this most recent dying star. WFAE's Lisa Miller spoke with Reynolds about the significance of finding such a young supernova in our galaxy.
