000002734 520__ $$aThe Herschel Guaranteed Time Key Project “MESS” (Mass loss of Evolved StarS) has observed a wide variety of evolved stellar objects in spectroscopic and photometric mode using both the PACS and SPIRE instruments on board the Herschel satellite. The aims of the project are to study the nebular morphology at far infrared wavelengths, the mass loss history of the central star, and the properties of the dust that was formed in the ejecta. In the poster we presented the results of the Herschel PACS and SPIRE imaging of the dust shell of the Helix planetary nebula NGC 7293.
