The Herschel space observatory is a scientific mission of the European Space Agency (ESA). The space telescope is dedicated
to the study of the cold universe by performing astronomical observations in the far infrared and submillimetre parts of the
electromagnetic spectrum. The guaranteed time key programmes for the study of star formation with the PACS and SPIRE instruments
focus on imaging star-forming regions in the Gould Belt and in giant molecular clouds across the Milky Way. The guaranteed
programmes are the Gould Belt survey and the HOBYS survey. Regions such Taurus, rho-Ophiuchi, Orion, Vela and Cygnus X will
be studied. 600 hours are devoted to these programmes.
