Regarding this post …
Any electron microscope image you have ever seen is falsely colored. They are imaged using electrons, not light, so everything you’re looking at was reconstructed by a computer in order to produce the beauty of smallness. It comes out in black and white, and then they are manually colored by artists. Sometimes, those artists get a little silly (and scary).
Same with all those Hubble telescope images, actually (check out this video to see how they make ‘em). Those are imaged in several different wavelengths, with sometimes hundreds of single images individually colored and edited to make all that gorgeous spaceporn.
These kind of things are a trade-off. They let us add a little imagination to that which is beyond our vision, but we have to make sure that the imagination is true to science.
