That's scientists' latest estimate for our galaxy alone, based on Kepler data
Roughly one out of every 37 to one out of every 70 sunlike stars in the sky might harbor an alien Earth, a new study reveals.
These findings hint that billions of Earthlike planets might exist in our galaxy, researchers added.
These new calculations are based on data from the Kepler space telescope, which in February wowed the globe by revealing more than 1,200 possible alien worlds, including 68 potentially Earth-size planets. The spacecraft does so by looking for the dimming that occurs when a world transits or moves in front of a star.

Numbers are off. Drake Equation did not include enough factors. The authors of the article need to read Ward & Brownlee’s “Rare Earth: Why Complex Life Is Uncommon in the Universe.”
Prove it: show me one.
So is there a planet with just women out there?
NOW, if only we could find ourselves James T. Kirk and the warp drive on Enterprise, perhaps we could find them, that would just be dandy, wouldn’t it?
You got that right. More scientific guessing with nothing concrete to go on.
Eventually, we will get this one little radio message from beyond our world...and then...our entire vision of the universe will change overnight, and likely scare us to death.
Can’t show you an Alien Earth, but proof of Alien Life Forms exist on MSNBC.
Only 2-billion? I say there’s at least a Trillion. Prove me wrong!
>Prove it: show me one.
Head down here to L.A. Their language ain’t English, that’s for sure.
This could be interesting.
I take it neither of you actually read the article?
Astronomers have discovered rocky planets orbiting stars, and they're orbiting stars in the "right" zone - the zone that would allow for liquid water to exist.
There have been four such discoveries, and the scientists are predicting that if their equations are accurate, eight more should be discovered in the next several years, bring it to a total of eight. After that, it just becomes a process of statistical probability to predict how many exist in the galaxy in total.
You're just begging for a Helen Thomas pic aren't you?
I wonder if they have the internet, ipod’s, video games, mini malls, mcdonalds, etc.. /sarc
Until they land on one, or see it looking Strangely Earthlike - with life and stuff - through a telescope, it’s just a rocky planet orbiting its sun, not an “Alien Earth.”
We are not alone. We wish we were, but we are not.
Actually, most civilizations that are just a bit more advanced than ours have probably gone dark from our perspective, because radio waves are a fairly primitive technology to makre use of.
Infinite for sure, besides higher spritual realms, I don’t want anymore physical worlds I die on, Come Lord..
Perhaps God has a separate covenant with another species on a separate planet.
It has been said that our planet is perfectly situated in the galaxy (which itself if perfectly situated in the universe) to best observe the cosmos.
