The Herschel Gould Belt survey is focused at unraveling the earliest phases of star formation. In addition, one of the main goals is to survey the - surprisingly complex and beautiful - structures of nearby molecular clouds in great detail at various stages of their evolution. In this contribution we present our first results from PACS and SPIRE far-infrared -- 70 to 500 μm -- observations of the Chamaeleon Star Forming region.
We highlight results on several aspects of this survey:
* Far-infrared flux measurements of known protostars and pre-main sequence stars are used to extend their spectral energy distributions, thus providing further constraints on their circumstellar components;
* New far-infrared compact sources (cores) are identified using a multi-wavelength source extraction code (getSources) and a preliminary comparison is made with mm cores to bridge the gap between the mid-infrared and mm wavelength domains;
* A first analysis of the filamentary structure - typical length scales, alignments, - of the cold ISM is presented.
