They are less expensive that actually sending astronauts.
They can detect elements that light telescopes can't.
Radio waves indicate a lot of tel-tale things that may indicate the possibility of life on those other heavenly bodies.

Disadvantages:

We can't be sure until we get there...or it gets here.
It's a tricky and sometimes high-maintinance thing to keep these telescopes and/or probes up there doing there thing.
