Wow.
Just a few years ago, this would have been far simpler, and we can only imagine the range of systems which will be known just a few years into the future. You have to think there will be life *somewhere* out there, right?
No word on whether R2D2 has a missing map segment to show more systems :)
[Apropos: an interesting answer to Fermi's paradox*: the aliens are silent because they are extinct. "In research aiming to understand how life might develop, scientists realized new life would commonly die out due to runaway heating or cooling on their fledgling planets." Even life on Earth has only existed for a relatively short period of time, cosmologically speaking...]
