This image has all the new worlds discovered by Kepler. The total is now 3,538. The big balls are actually stars. The planets are the tiny black dots in front of them, shown to scale. It's ridiculous.
Ridiculous because it's nothing: Scientists now estimate that one in five Sun-like stars have Earth-sized planets in habitable orbits, or about 20 billion. Just in our galaxy. That makes the possibility of alien life almost—if not totally—impossible to deny.
