Perhaps this is a bit of a dumb question; I'm gonna ask it anyway. I like those beautiful photos of stars and such. Also I read some times about false color photos, where there is a blend of different pictures of different spectra of light. And I read something about red-shift and blue-shift where stars coming towards us are more red colored and stars traveling away from us color blue. How does this fit together in pictures of, for instants hubble? the beautiful colors in those pictures, is this real? when we would travel to those star formations, do we see those colors like that or not? And a red giant star, is this truly a red colored sun?
