The ATLASGAL survey covers two-thirds of the surface area of the galaxy within 50,000 light-years of the galactic center. Thus, it includes practically all (97 percent) of the star-formation within the solar circle, i.e. the inner galaxy. The image displays a part of ATLASGAL, a region located between the giant molecular complexes called W33 and M17 in the Sagittarius constellation. Zooms in color scale show the 3-color emission from the mid-infrared GLIMPSE survey, and sub-millimeter dust emission from ATLASGAL is shown in red and traced with contours. One region corresponds to a cold pristine massive clump (upper left inset) and another one to a young massive star (upper right inset). Both objects have sizes of only a few light-years across. In the lower right inset, we present a schematic of the Milky Way and show the position of the solar circle (green) and region of the galaxy covered by ATLASGAL (shaded region).
