Telescope “Kepler” found a dozen potential twins of the Earth


The American space Agency NASA issued a press release in which it is reported that recently the space telescope Kepler (Kepler) found 219 new candidates for exoplanets, including ten possible planets located in the so-called habitable zone of its star, and therefore potentially suitable for the emergence and development of life.

Exoplanets are planets located outside the Solar system. To detect them successfully because of that, passing over the disk of their stars, they “block” it, slightly changing its brightness. However, each such opening requires additional checks to be deemed confirmed.

Of particular interest to specialists are exoplanets located in the habitable zone, i.e. at this distance from the star where water could remain in liquid form, not freezing from too low temperature and not evaporating too high. Among the objects that have been discovered by “Kepler” for the last time, ten can not only be located in the habitable zone, but also to resemble the Earth in size. On such planets, according to existing concepts, the chances of finding life is highest.

Telescope “Kepler” is the first astronomical satellite, specifically designed to search for exoplanets. With this purpose, the spacecraft is equipped with a sensitive photometer, designed specifically for this purpose. The probe, launched in March 2009, named after the German mathematician and astronomer Johannes Kepler, is recognized as the discoverer of laws of planetary motion in the Solar system. They were only discovered about four thousand objects, most of which confirmed the status of the planets. 30 of these exoplanets resemble the size of Earth and located in the habitable zone. Also among the discoveries made with a telescope, you can call the youngest planet known to science today — its age is 5-10 million years. About the opening of this space of the body became known a year ago, it belongs to the class of “hot Jupiters” and is situated at a distance of about 500 light-years from Earth.
