Giant filaments of cold dust stretching through our Galaxy are revealed in a new image from ESA’s Planck satellite. Analysing these structures could help to determine the forces that shape our Galaxy and trigger star formation.
Planck is principally designed to study the biggest mysteries of cosmology. How did the Universe form? How did the galaxies form? This new image extends the range of its investigations into the cold dust structures of our own Galaxy.

Filamentary structures are apparent on large scales (as shown in the Planck
image, right) and small scales (as seen in the Herschel image of a region in the
Aquila constellation, left) in the Milky Way. (ESA/Herschel/SPIRE and PACS
