| Description | Recent Herschel observations have detected up to 0.7 Msun of cold dust surrounding SN 1987A . This discovery implies that supernovae could be responsible for the large dust masses detected in high red-shift galaxies and opens opportunities in the Herschel era for detecting and measuring accurate cold dust masses in extra-galactic supernovae. One data point from SN1987A is insufficient to resolve the fundamental question of the origin of dust in early Universe, therefore we propose Herschel PACS and SPIRE imaging observations of the two nearby supernovae SN 2004et and SN 2004dj. After SN 1987A, they are the closest well-known supernovae with evidence of dust formation from Spitzer and other ground-based observations. Our scientific goals are i) to detect far-infrared and submm emission from supernovae, ii) to understand the spectral energy distribution of the SNe for temperatures and dust composition, and iii) to estimate freshly formed dust mass. These added observations are essential to help determine if supernove are significant dust makers in the early Universe. |

| 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. |
