It looks like obtaining true-colour images can be a tricky process involving multiple exposures using different filters. It would be interesting to know exactly how many steps the space photos we see go through before we reach us. We have to take a lot on trust!

Isn't that a false colour image?

So those colours are merely what some operator with an image processing package chose to make them to make UV and IR visible.

I guess this is true for all the photos if galaxies that we are shown. Horsehead nebula, whatever, I seem to remember all of them in more than one color. Does anyone know where to find un-colored images? I'd guess that they're either white or invisible.
Check out the original images that went into this composite here here
