A lot of people misunderstand the coloring they see in these space photographs. As pretty as they are, much of the time they are taken by telescopes that only detect light outside of the visible spectrum. Many of these photos are then "colorized" through post-processing as a way to distinguish the differing levels of whichever type of light they were originally taken in (radio telescopes, x-ray, gamma ray, etc...)

Still, they did do a nice job filling in the visual gaps our own eyes fail to see. :thumbup:
