A mere four light years, our nearest neighbour. So at least messages will only take 8 years round trip. There was some recent speculation about a type of probe potentially capable of velocities up to 1/4c as I recall but I can't recall the details.

Dude I had no idea that radio waves etc would travel at the speed of light in a vacuum. Very cool.

Radio waves and light are both the same electromagnetic radiation, just different energy levels.
