Do I understand correctly, that all colours on these pictures always are purely artificial? That is, all visible light we can see through any telescope is always white, and only some minor differences in the spectrum, invisible to us, are used to detect what elements there are, and then semi-artistically colorize the picture based on that data?
- spindle 6y agoMany objects in the sky are brightly coloured. Astrophotograpers often add artificial colours on top of (or instead of) the actual colours. Plus, much of what you see from astronomers (although not from this case) is taken in non-optical parts of the electromagnetic spectrum (e.g. radio waves or x-rays), so those pictures are necessarily artificially coloured.
