Subject: Could someone use the electromagnetic fields of the planets and sun?

I know that someone will probably be too famous for actually figuring this out 
but here we go... If we can use an antenna here on earth to to 'repeat' a 
signal to another place on earth, could the same thing be done using the 
earths, or sun's electro magnetic fields? Basically what I'm getting at here 
is, would it be possible to use these enormous fields to peer further into 
space? Or just maybe get a better view of the asteroids and comets in the solar 
system? I'm not doing a science project or anything just a fellow thinker 
that's not afraid to give out really good ideas (if they work). I would like to 
hear some kind of criticism on this, good or bad. And if possible what kind of 
benefits this would bring to science if more study were put into this.

Thank You All. Keep Thinking,
Chris
