It's unclear what mapping was used in either image, or indeed, which filters. As a rule, color images have little scientific value. They are created for press releases and education, not science. So the choice of colors is often aesthetic, or intended to emphasize particular structure. This is particularly true where some or all of the data is completely outside the human visual spectrum, and where more than three filters are used.I found it here: https://www.nasa.gov/universe/a-cosmic- ... asas-webb/Where did you find the Tarantula image? (And to me, it looks like both the images you provided are using the same palette.)I'm still somewhat puzzled by JWST colour choices. Is there a scientific reason why they chose pink/red for NGC 604 but a kind of rusty brownish not-really-red for the Tarantula Nebula? Is it to reflect different molecular properties or are these different colours for no real reason?
