    False color images taken by satellites
    Nebulae have always fascinated me. Some of them astound me. Are the false color images colored by humans?

    Here's some of my favorites

    Yes - Most cameras that are used only measure intensity - not color. So an artist has to come along later to make it more interesting for publication by adding color.

    Yeah, they really are beautiful!

    Oh, and to answer your question, in short... no! A computer does it all!

    Here's a good page that describes it to a good depth;
    Glossary: LRGB Color Production

    *edit*

    Apparently, some of the colours are added by humans! Ha ha, sorry!
