Astronomers studying this infrared image believe that the dark hole -- called NGC 1999 -- seen in the green cloud at the top of this image contains fledgling stars. One of the stars is thought to be heating up the surrounding space dust and creating the bright greenish glow. The red in this image is a cloud of cold, dense gas and dust -- which forms the embryonic raw material that is the stuff of new star formation.
