Processing galactic images with both JWST and HST data is just incredible. Normally, every spiral galaxy (and some elliptical ones too) have dark dust lanes obscuring the light from the stars behind. These dark spirals add depth to the image, but unfortunately don’t contain much information. But with the added infrared imagery, the glowing strands and flocks of dust, which would normally be dark in visible light imagery, are instead bright and glowing with infrared light from JWST.
Below is a comparison of the Hubble visible-light image and the JWST infrared image
Data detail:
The Hubble image was created from HST data from proposals: 10402: R. Chandar et al. 9796: J. Miller et al.
The JWST image was created from JWST data from proposals: 2107 J. Lee et al.
