• NASA announced the discovery of seven Earth-like planets
The National Agency for Aeronautics and Space Administration (NASA) announced that it has found 40 light years from the solar system, seven new planets, with characteristics similar to Earth.
Planet found orbiting red dwarf star ultracold TRAPPIST-1. Each of these is comparable in size with the earth, and is also found in the so-called habitable area - i.e. in the region where sufficient light and heat in order to find the water in liquid form.
In addition, according to scientists, four of the seven planets may even be suitable for the existence of extraterrestrial life on them. "The discovery of a second Earth is - not a question of" if ", but a question of" when ", - said the deputy head of the Directorate of Scientific missions of NASA, Thomas Tsurbyuhen.
"The planets are all close to each other and are very close to the star, much like the moon around Jupiter.
However, the star is so small and so cold, that the planets may be liquid water and possibly life, "- said astronomer at the University of Liège Michel Guyon. According to astronomers, open these exoplanets managed by the Space Telescope "Spitzer". Moreover, this discovery they considered the most important of those that managed to do this with the help of a telescope.
The astronomers also observed that seven open their planets are relatively close to the earth, but to fly to them, for example, on a jet plane, it would take about 40 million years.
Until now, scientists have known for a few tens of planets that are considered "twins of the Earth." So called hypothetical Earth-like exoplanets that are located within the habitable zone of a star and may be suitable for life.
At the same time, no evidence of the life of a scientist could not be reached on these planets.
