One thing that is of great interest is the fact that planets are discovered at all and not just hypothesized. The increase in tech level just the past decade or so that makes it possible to in some cases get pictures of exoplanets, is truly remarkable.
As for the Quest for alien life forms, well, got to get out there first. Sitting here won't give us anything to discover. Unfortunately, interstellar travel is slightly more complicated than Star Trek wants us to believe.
