Colourful clouds of star-forming gas and dust host stellar nurseries
Herschel reveals filaments in the Serpens Core
This image from ESA’s Herschel space observatory shows the Serpens Core, the heart of a giant molecular cloud. These giant clouds are complex formations, most often made up of filaments mixed with clumpy and irregular folds, sheets and bubble-like structures. A typical spiral galaxy like the Milky Way can contain thousands of them.
