The belief that we are not alone in the universe is taking more and more strength. Scientists
WM Keck Observatory in Hawaii have discovered a planetary system like ours where there is high probability that life could arise. In particular this system is in the constellation Libra, your star called Gliese 581 and there are no fewer than 3 planets that could harbor life.
The closest to the star Gliese 581 C is located right on the border within the "habitable zone", which is the area where you have to be a planet so that the distance from its star is the optimal conditions exist favorable to life.
The farther from the star is Gliese 581 D, on the outer edge of the habitable zone is much colder than before and therefore would require a dense atmosphere that would make greenhouse.
These two planets are at the ends of the habitable zone on opposite sides could have the necessary conditions to support life, but right in the perfect spot on the habitable zone of this system is the planet Gliese 581 G which is just the right distance for liquid water may be having a gravity similar to Earth, thus also providing air, like the Earth has a warm and a cold zone, is 3 or 4 times larger than Earth and unlike Earth, it spins on its axis, which means that there are always lit and one side always dark. Is the planet with better conditions after the Earth for life found so far.
The exoplanet so similar to Earth is only 20 light years away in astronomical terms is relatively small.
According to one of the researchers find, the chances that life exists in these newly found planet is ... 100%! OO
hope that their predictions are fulfilled and we hear about it soon.
