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 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. Scientists at NASA's Jet Propulsion Laboratory in Pasadena, Calif., focused on roughly Earth-size planets within the habitable zones of their stars — that is, orbits where liquid water can exist on the surfaces of those worlds. [The Strangest Alien Planets] "This means there are a lot of Earth analogs out there — two billion in the Milky Way galaxy," researcher Joseph Catanzarite, an astronomer at NASA's Jet Propulsion Laboratory, told SPACE.com.

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.

The privilege of viewing earth from space is only granted to a very select few. However, thanks to these images, it is almost like we get to go up there ourselves. The real kick is, we’ve seen images like this before, created in special effect studios in Hollywood. . [34 pictures] Hint: Use “J” and “K” keys to navigate from picture to picture.
