Stellar Winds

In this image, a young star cluster called DR22 emits winds and harsh ultraviolet light that sculpt the remnant cloud into fantastic shapes. Astronomers are not sure when that activity suppresses and when it fuels future star formation. The cluster is in the constellation Cygnus the Swan. This image was taken during Spitzer's warm mission.
