In the image, a face-on spiral galaxy is split diagonally: James Webb Space Telescope observations appear at top left, and Hubble Space Telescope observations appear at bottom right.

The differences in the observations are shown as a striking contrast, the opposite of dark and light. NASA James Webb shows dust glowing in infrared light, while NASA Hubble's visible light view tells us where starlight is absorbed by dust.

Image description:

A panning view of two diagonally split images of the spiral galaxy NGC 628, Webb's at top left and Hubble's at bottom right. The nucleus of the galaxy is roughly centred and the arms appear to rotate counterclockwise. The structure looks like a cross-section of a nautilus shell. In Webb's image, the arms are composed of dark grey or black "bubbles" and orange-red filaments, with a blue haze near the core. In Hubble's image, the arms are a mixture of bright blue star clusters, pink star formation areas and dark brown dust lanes, and the core is pale yellow.
