So here are the two images again. See how many of the same structures you can spot, dark in the visible-light image and bright (thermal glow) in the far-infrared image! 4/

Two images of the Andromeda galaxy one above the other. The top image is in visible light; it's the one I created from images taken with my Seestar S50. The bottom image is in far-infrared light, by ESA's Herschel Space Observatory.

It's easier to see the similarities if you take a smaller region from each image and put the two next to each other. Here is one from the right-hand part of the two images. 5/

Zoomed-in regions from either image. The darker structures in the visible-light image (top) have the same shape as the brighter structures in the far-infrared image (bottom).
