In the Feynman Lectures on Physics, he writes (and I paraphrase from memory) ... "What if the rainbow, instead of being produced at visible wavelengths, was all in the radio band? Then, one day, by chance, some radio astronomer scans that region of sky and finds a circular arc of radio energy being emitted, with various wavelengths separated into bands, shortest wavelengths at the center edge, longest wavelengths at the outer edge. Would a scientist call that data structure 'beautiful,' or simply 'interesting'? Most, I think, would call it beautiful, even before it became an image." Feynman was speaking about beauty in science in a very general sense. Some equations have that symmetry or patternicity or recursiveness that cause them to be described as "beautiful." But the average person just doesn't "get it." Now if we took an image of that "radio rainbow" and assigned false colors to it, but explained in the caption that it was done to make something normally invisible to the eye become visible, most non-scientists would see the beauty. So my wisdom (actually Feynman's wisdom) is that false coloring is OK, as long as you include the disclaimer.

It is an odd sensation to look at these images: The arbitrarily assigned colors relate to actual features across selected areas of the electromagnetic spectrum, but I worry that the public is getting a false idea that the universe is full of incredibly luminous, brightly colored, gaudy objects as shown in these images (and in spite of the clear explanations regarding colors that are usually in the captions). The human experience is totally different, even if you were transported there to see it up close and personal. You can't call it science fiction because the colors represent something real and important that's actually there. But..... conflicted thoughts on all this. What if the public only ever knew the Grand Canyon in selected wavelengths across the electromagnet spectrum and colored up to look psychedelic? > > What's your wisdom? > > I often find myself kinda longing for the old Mt Wilson B&W photos of galaxies--maybe because I found them so inspirational as a kid and because they're close to what I see in my 25".
