| Description | The Helix Nebula is one of the most spectacular Planetary Nebulae in the sky. Due to its size it is particularly well adapted to study the physical conditions of the gas and dust submitted to a very strong UV field. In order to obtain the physical conditions of the dust along the different shells of the nebula a deep photometer map of the whole nebula will be made with SPIRE, revealing the blobby structure and constraining the dust emission. The gas properties will be traced by observing four selected positions along the shells with SPIRE-FTS in order to trace the change of physical conditions (temperature, density, molecular abundances) as a function of the distance to the central star. |

| 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. |
