Just to be clear, this image is heavily processed by a grad student who studies planetary atmospheres....scaled 2x, colours added, etc. This is not an original unprocessed image from JWST.

Are any images from JWST unprocessed? Aren’t they looking at the below visible spectrum? 🤔

Yeah they’re all processed, they are IR so they assign visible colors to different IR wavelengths I assume

Neither was Hubble mostly. You can go to NASA site and see before and after Hubble shots.

There are 3 or more stages at of image processing to create a final scientific image for JWST’s infrared cameras. The “unprocessed” images are literally uncorrected for effects like detector sensitivity/artifacts/cosmic rays/dead pixels/saturated pixels/read noise/etc etc etc etc. And even then they are still just raw arrays of flux per unit area with absolutely no intrinsic instructions on how to scale those values to brightness in an actual visual image. There no such thing as an “unprocessed” image in astronomy or photography digital or analog that somehow shows a more honest or objective depiction of its subject.
