3 Views of W49
Description
These images show the W49A star forming region in context. The top image (Haslam, C. G. T., Salter, C. J., Stoffel, H., & Wilson, W. E. 1982, Astron. Astrophys. Suppl. Ser., 47, 1) shows the location of W49A in the galactic plane. The middle image shows the 3.6 cm emission from W49A. The image indicates the presence of a large number of HII regions in a small region of the sky. W49A is perhaps the best galactic example of starburst phenomena. The bottom image shows a detail 7 mm image of the most highly obscured region in W49A. None of the regions visible at 7 mm are detected at infrared or optical wavelengths, being deeply embedded in a molecular cloud.
