Studys shows that it is unlikely that we are alone in the Universe

Are we alone in the Universe? Is so rare , would be the existence of potentially habitable planets? Questions like these, doubts the most interested in the topic, especially to astronomers .

Whether there is extraterrestrial beings on other planets , is a question that hangs over us. Especially when we know what is out there, scattered in the Universe, identical to Earth and planets in the same conditions .

But these planets are so rare ? In not true . According to a study recently published in the Proceedings of the National Academy of Sciences, one in five star similar to the Sun have planets in the Habitable Zone. These data were obtained with the help of NASA's Kepler spacecraft.

If so, this could mean that there is at least one area only 12 light years from Earth planet. For us lies too far, why not (yet) we have sufficiently advanced technology to get there. But in galactic terms, is extremely close .

If these planets also support life, is of course another matter. However, in theory there should be conditions.
