Broadband images of the Condor galaxy used here. The U 4.5 μm bands highlight progressively cooler stars in the arms, nucleus, and central bar of the galaxy. Increasing dust (PAH) emission at 5.8 and 8 μm highlights warm ISM in the arms and a ring that encloses the stellar bar. GALEX UV images are dominated by star forming regions in the arms, and reveal hot stars in the TDG candidate at the tip of the NE arm.
