RGB view of about half of the CMZ (~50′ × 60′) in the GC. Red: SPIRE 350 μm tracing cold dust from the most prominent molecular clouds. Green: PACS 70 μm tracing warm dust, mostly in extended PDR-like environments. Blue: MIPS 24 μm tracing hot dust, mostly from ionized regions. The rhombus marks the ~13′ × 13′ area mapped with SPIRE-FTS around Sgr B2(M,N) massive star-forming cores.
