New data Astronomical Satellite NASA "Kepler" evidence of the billions of Earth-like planets that are much closer than they could imagine scientists.
"The information we publish today, will delight the general public, as we have found that the nearest Earth-like world is within 13 light-years from the Sun" - said the astronomer Courtney Dressing.
"In astronomical terms, 13 light-years - is very close."
Mathematical calculations have shown that the number of twins land in our galaxy is astronomically high.
Scientists estimate that 6 percent of the $ 75 billion of red dwarf stars have planets the size of our Earth, which revolve around them, perhaps at an acceptable distance for life. Thus, we arrive at the number at 4.5 billion Earth-like planets.
But even if planets like Earth are relatively close to us, at a distance of 13 light years, if we can see them with the help of modern technology?
"Future missions such as the James Webb Space Telescope (Hubble’s heir) and the proposed projects are extremely large ground-based telescopes such as the Giant Magellan Telescope, will allow us to know the composition of the atmosphere closest habitable planets," - said the Dressing.
"These missions will be able to find biosignatures, such as oxygen, which may lead to the announcement of the presence of life on another planet."
The results of this study will be published in The Astrophysical Journal.
