Step Inside a Supernova

In this Smithsonian collection, students explore the life cycle of stars and learn about the connection between elements and space. They'll explore real data that provides evidence for the dispersal of several elements produced by the explosion of massive stars, specifically through the Cassiopeia A supernova. Then they’ll put their knowledge into practice by navigating the remains of the supernova in the online interactive “Journey through an Exploded Star.”
