Sci fi channel ident

I found this sci fi ident on dailymotion.com. I wanted to find out how the sci fi logo appeared on the screen at the end of the ident. A couple of things I have noticed are the way the sky has been edited to make the image more sci fi orientated. Finally the way the purple and black fades in before the logo appears. This has been done in after effects although I'm not exactly shore how.
