The tool of spectropolarimetry applied to supernovae has shown that core collapse supernovae are strongly asymmetric and that Type Ia supernovae are less so, but still systematically asymmetric. These studies will lead to new insight into the explosion mechanisms of both core collapse and thermonuclear supernovae. The latter may give long sought clues to the binary nature of Type Ia and new insight into the origin of the observed scatter in the properties of Type Ia that may help to make them even more precise tools of cosmology. We will show in this poster observations of the Type Ia supernova SN 2001el and SN 2004dt, and several core-collapse supernovae observed by the VLT and the Subaru Telescope.
