Hi-GAL is coming !!!
This fantastic picture is a 70-170-350um composite image of the Galactic Plane at the longitude of 59° in the Vulpecula region. Most remarkable features that can be seen are shock fronts from HII regions, bubbles, Interstellar medium structured at all scales, and remarkable filamentary structures with on-going star formation.
Hi-GAL is the Herschel Open Time Key-Project that will map the entire Galactic Plane of the Milky Way (-1° < b < +1°, following the Galactic warp) in 5 bands between 60 and 600μm at a diffraction-limited 4-40" spatial resolution. Thanks to subsequent allocation of observing time obtained in the three Herschel calls for proposal, Hi-GAL is now the largest Open time Key-Project of the Herschel mission with almost 900 hours observing time for a total mapping area of 720 square degrees.
