Description:

This image shows the head (facing right), shoulder and arm region of IC 1848, The Soul Nebula, a star-forming region lying 7500 light-years from Earth. Dark molecular clouds form the right "eye" of the Soul's "face". The "mouth" is comprised of a separate IC object, IC 1871, which has an intriguing structure that looks like a whirling tornado extending off the tip of its triangular cloud. The majority of the nebula glows red in the hydrogen-alpha wavelength due to ionization of hydrogen gas by the hot blue type O and B stars born of the nebula.
