This image is part of the Herschel infrared Galactic Plane Survey (Hi-GAL).
It covers approximately 2×2 degrees on the sky (as an indication, the full moon is 0.5 degree across) centred at 290 galactic longitude. The Herschel satellite offers the optimum combination of instruments to efficiently map the emission from dust particles spread throughout the Galaxy.
Hi-Gal is an unprecedented survey of our Galaxy at infrared wavelengths.
It will provide astronomers with a publicly available dataset of extraordinary accuracy designed to serve their scientific needs for decades to come.
This survey will help address some fundamental astronomical questions. For example: how much dust is there in the Galaxy, and what fraction of the overall galactic mass does this represent? How do the proportions of dust to gas vary throughout the Galaxy? How efficiently do stars form in different parts of the Galaxy? How similar is our Galaxy to others in terms of star formation?
