Abstract
Type Ia Supernova already represent a valuable tool for astronomical exploration by providing a bright standardizable candle, however, they also represent an opportunity to observe the matter in the universe along the line of sight. A study of the spectra of Type Ia supernovae reveals a variety of contamination of these spectra at a variety of locations, including the Milky Way galaxy, a source likely local to the original supernova and an as yet unidentified source of contamination. Further, Type Ia Supernova appear to change with the redshift of the supernova.
