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.

New estimate for alien Earths: 2 billion in our galaxy alone

These findings hint that billions of Earthlike planets might exist in our galaxy, researchers added. These new calculations are based in 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. Have We Found The Universe That Existed Before The Big Bang?

Beautiful Planet - Oh I so want to go to the ISS!

Well it certainly looks heavenly from the ISS. Time to order a large drink, you know, one with a lot of fruit and a little umbrella, then stretch out on a hammock and just enjoy life, watching what I can only imagine a marvelous sunset.
