( -- Cygnus X hosts many young stellar groupings.

The combined outflows and from the region's numerous massive stars have heated and pushed gas away from the clusters, producing cavities of hot, lower-density gas.

In this 8-micron , ridges of denser gas mark the boundaries of the cavities. Bright spots within these ridges show where stars are forming today.
