A weak cosmic infrared radiation field that reaches Earth from all directions contains not yet deciphered messages about the evolution of galaxies.

Using first observations with the PACS Instrument on board ESA’s Herschel Space Telescope, scientists have for the first time resolved more than half of this radiation into its constituting sources.

Observations with Herschel open the road towards understanding the properties of these galaxies, and trace the dusty side of galaxy evolution.
