Another Stellar Gestation and Birth in the Milky Way


This image is a PACS/SPIRE three colors composite images (blue=70um, green=160um, red=250um) which unveil our own Milky Way Galaxy as one giant nursery where generations of new baby stars are continuously born.

This image is taken in constellation of Vulpecula and shows the entire assembly line of newborn stars. The diffuse glow reveals the widespread cold reservoir of raw material which our Galaxy has in stock for the production of new stars. Large-scale turbulence possibly due to giant colliding
Galactic flows causes this material to condense into the web of filaments that we see throughout the image, and that will act as "incubators" where the material becomes colder and denser.

Eventually gravitational forces will take over and fragment these filaments into chains of stellar embryos that can finally collapse to form infant stars.
