| Description | We propose a pilot program to investigate the nature of the non-standard extinction law of Type Ia supernovae through sub-mm observations near the supernova lightcurve maximum. If scattering and absorption by circumstellar dust contributes to the observed extinction, dust emission at sub-mm wavelengths is expected. Thus, we plan to target nearby reddened Type Ia supernovae around peak luminosity. A detection of sub-mm emission from the supernova location would dramatically improve our understanding of the processes behind the dimming of supernovae, with far reaching implications for their use as distance indicators in cosmology. |

| Mission Description | Herschel was launched on 14 May 2009! It is the fourth 'cornerstone' mission in the ESA science programme. With a 3.5 m Cassegrain telescope it is the largest space telescope ever launched. It is performing photometry and spectroscopy in approximately the 55-671 µm range, bridging the gap between earlier infrared space missions and groundbased facilities. |
