Welcome to the HOBYS/Herschel key programme Web page

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 HOBYS guaranteed time key programme for the study of star formation with the PACS and SPIRE instruments focuses on imaging star-forming regions in giant molecular clouds across the Milky Way. Regions such Orion, Vela and Cygnus X will be studied. 120 hours are devoted to these programmes.

Hunting high-mass stars with Herschel

In this new view of a vast star-forming cloud called W3, ESA’s Herschel space observatory tells the story of how massive stars are born.

W3 is a giant molecular cloud containing an enormous stellar nursery, some 6200 light-years away in the Perseus Arm, one of our Milky Way Galaxy’s main spiral arms.

Spanning almost 200 light-years, W3 is one of the largest star-formation complexes in the outer Milky ...
