US scientists from NASA and other research centers reported the discovery of eight exoplanets, one of which claims to be the “second Earth”, the “BBC Russian Service”.
New exoplanets, the physical conditions on the surface which may be close to the earth.
The planet in question, designated Kepler 438b. It is 12 percent larger than Earth and, according to astronomers, probably more like Earth than the previous candidate for the title of “twin” – the planet Kepler 186f.
In this Goldilocks planet orbiting a red dwarf star that is at a temperature significantly lower than the temperature of the sun. In this case, the planet should get about 40 percent more heat than the Earth, because of the nature of its orbit.
As said Dr. Doug Caldwell of the Search for Extraterrestrial Intelligence Institute in California, this planet is at a distance of 475 light years from the earth and the physical conditions on its surface can only guess. Scientists do not yet know of any species is composed of the planet – more or less accurately established only its approximate diameter and orbital parameters.
search for extrasolar planets outside our solar system has been a European telescope “Kepler”. Currently, he has found more than a thousand of these celestial bodies. True, only three of them are in the so-called “Goldilocks zone”, that is the right distance from its star, which provides roughly the same range of temperatures on the surface of the planet, as on Earth.
The current astronomical technology has can not get the real picture even those closest to us exoplanets, which are fixed orbital and ground-based telescopes. The creation of such a telescope will be a revolution in astronomy.
