From blue to red, the colors represent filters centered at 100, 160 and 250 micron. Extended emission at these wavelengths are due to thermal emission from dust. The bright region in the image is the 30 Doradus star formation region, in which a lot of warm dust is present. The redder emission from the rest of the galaxy reveals the presence of vast amounts of cold dust. Result from the HERITAGE survey (Meixner et al. 2010, A&A 518, L71; Meixner et al. 2012, submitted).
