Study Estimates 100 Billion Planets In the Milky Way Galaxy

The Bad Astronomer writes "A new study finds that there may be 100 billion alien planets in the Milky Way alone, with 17 billion of them the size of Earth. Announcements like this have been made before, but this new research is more robust than previous studies, using data from the Kepler planet-hunting spacecraft over a longer period and analyzing it in a more statistically solid way (PDF). They also found that smaller planets are not as picky about their host stars, with terrestrial planets forming around stars like the Sun or as small as tiny, cool red dwarfs with equal ease."

  1. Alien? by DarthVain · · Score: 5, Funny

    So are they saying there is 100,000,000,001 total planets? Thats some accuracy!

    Are planets in our Solar System "Alien" or are we claiming ownership over them?

    I think they just wanted to use Alien in the summary.

    640k ought to be enough for anybody.

  3. Goldilocks zone by jasonvan · · Score: 5, Insightful

    I wonder if there is any way to statically guess the number of planets in the Goldilocks zone, the approximate distance from a star for liquid water to be possible. That would be a very interesting number but I'll just throw out a guess there will be more than one. It's remarkable to think of all the possible life that could be out there. We are probably destend to never meet, but it's interesting nonetheless. I think one of the greatest things finding life elsewhere would accomplish if it ever were to happen, is to study evolution on a completely different scale. The diversity on Earth alone is remarkable, to think what an entirely different planet might produce makes my imagination go wild.

    Your only hope is to start hanging around in English bars and keeping an eye out for a weird looking dude carrying a towel.
