Virtually no distant astronomical image is a normal photo that corresponds to what the human eye would see.
They're multi-layer stacks of CCD observations filtered by frequency range, with false colors then assigned, not three RGB layers. IIRC, typically there's 7 - 11 ranges, depending on the instrument.
So one of the layers included in the depiction might be infrared, then false-colored into something the eye can handle.
