Spitzer's image of NGC 3627 shows a face-on barred spiral galaxy anchored by its central region, which has a bright blue central dot surrounded by a lighter diagonal blue bar structure made of a haze of stars. Two distinct spiny pink spiral arms stat at the end of the bar, rotating clockwise, and forming an S-shape.

Moving to slightly longer wavelengths, this is an infrared image of NGC 3627 from the Spitzer Infrared Nearby Galaxy Survey (SINGS).
We see a stark contrast between the blue core and bar with a concentration of blue older stars, and the pink bar ends and spiral arms that show dust heated by actively forming stars.
