ADDED - Type Ia supernovae have been celebrated for their use as standardizable candles and their central role in the discovery and exploration of dark energy. And yet, we have still not been able to determine exactly what type of star system explodes as a Type Ia supernova, or how the explosion itself occurs. In my talk, I will show how the last visible light from old, nearby Type Ia supernovae, more than 900 days after explosion, can be used as a new diagnostic to constrain progenitor and explosion models.
