What whispering distant stars Bashny.Net

For a long time the existence of planetary systems like solar remained open. But in the 90s the first exoplanet was discovered, and since then the number of such discoveries has been steadily increasing.

In space, it turned out a lot of gas giants, but the most interesting question - find potentially habitable planets in the habitable zone of planetary systems.

With this purpose in 2009, NASA launched the telescope "Kepler".



Transit method (ie, tracking those moments when exoplanet in rotation closes part of "their" stars) "Kepler" can detect exoplanets, comparable in size to Earth. For example, Kepler-186f was opened in April this year.
Approximately so are its artists themselves:



The size of this exoplanet was able to calculate, but its mass and composition are not yet known.
With the elucidation of such data generally associated with a number of difficulties: it requires huge telescopes power and a lot of money, and a perfect result you can not get. However, the scientist came up with Keyvan Stassun pretty nifty technique that can help solve some of these problems. Just need not analyze the light and sound.
