Galaxy NGC 7538

March 31, 2003
Atlas Image Mosaic, covering 11.0´ × 11.0´ on the sky, of the HII region NGC 7538, also known as Sharpless 158. The large emission region to the northwest corresponds to what is seen optically; this region is ionized by the bright, hot stars toward the center of the nebula. The region can be seen in the 2MASS image to be quite dusty; much of the starlight is being reflected by dust, giving the filamentary main nebula a purplish-pink hue. 2000 Nov 15-21
