We have been scouting out new planets for a few years now. First we started measuring a sun's 'wobble' to infer the mass and distance of it's planet(s). Before now we've never actually gotten a clear, direct image of an extra-solar planet.
I imagine that we'll (the we that is the Earthly Scientific Community) make more complex and exciting discoveries more frequently.
The BBC has a nice cache of these discoveries.
