A multi-wavelength zoom on G18.93/m, the continuum peak connected to the prominent IR extinction feature. The panels are (from left to right in reading order): 3.6 μm, 8.0 μm, 24 μm, 70 μm, 160 μm, 250 μm, from GLIMPSE, MIPSGAL, and HIGAL. The blue circles in the bottom right of each panel indicate the beam sizes, the green contours are from ATLASGAL (at 0.3 Jy, 0.4 Jy, 0.5 Jy, 0.7 Jy, 0.9 Jy, 1.3 Jy, 1.8 Jy, and 2.5 Jy). The colors of the source marked by a red arrow in the first panel are not consistent with typical colors of young stellar objects (class 0/1) (Gutermuth et al. 2008; Robitaille et al. 2008).
