Left panel: three-color image of molecular filament L1482; here, shown in red the 250 μm, green the 160 μm, and blue the 70 μm band (Harvey et al. 2013). The shorter wavelengths reveal hot dusts, such as the H ii regions (Sharpless-222; see Sharpless 1959) around the NGC 1579 stellar cluster, which are clearly shown in blue. The longer wavelengths show the cold, dense objects, such as the cold dense filaments plotted in red. Right panel: dust temperature map (36′′ corresponding to 0.08 pc) of filament L1482, with the column density N_H2 of molecular hydrogen contours overlaid. Contours are plotted from 6.3 × 10²¹ to 5.7 × 10²² cm^-2 with a spacing of 6.3 × 10²¹ cm^-2 (10% to 90% of the maximum spaced with 10% contour interval).
